Social capital and health : variations, associations and challenges

Although social capital and health have been extensively studied during the last decade, there are still open issues in current empirical research. These concern for instance the measurement of the concept in different contexts, as well as the association between different types of social capital and different dimensions of health. The present thesis addressed these questions. The general aim was to promote the understanding of social capital and health by investigating the oldest old and the two major language groups in Finland, Swedish- and Finnish-speakers. Another aim was to contribute to the discussion on methodological issues in social capital and health research. The present thesis investigated two empirical data sets, Umeå 85+ and Health 2000. The Umeå 85+ study was a cross-sectional study of 163 individuals aged 85, 90, and 95 or older, living in the municipality of Umeå, Sweden, in the year of 2000. The Health 2000 survey was a national study of 8,028 persons aged 30 or above carried out in Finland in 2000-2001. Different indicators of structural (e.g. social contacts) and cognitive (e.g. trust) social capital, as well as health indicators were used as variables in the analyses. The Umeå 85+ data set was analyzed with factor analysis, as well as univariate and multivariate analysis of variance. The Health 2000 data was analyzed with logistic regression techniques. The results showed that the Swedish-speakers in the Finnish data set Health 2000 had consistently higher prevalence of social capital compared to the Finnish-speakers even after controlling for central sociodemographic variables. The results further showed that even if the language group differences in health were small, the Swedishspeakers experienced in general better self-reported health compared with the Finnish-speakers. Common sociodemographic variables could not explain these observed differences in health. The results imply that social capital is often, but not always, associated with health. This was clearly seen in the Umeå 85+ data set where only one health indicator (depressive symptoms) was associated with structural social capital among the oldest old. The results based on the analysis of the Health 2000 survey demonstrated that the cognitive component of social capital was associated with self-rated health and psychological health rather than with participation in social activities and social contacts. In addition, social capital statistically reduced the health advantage especially for Swedish-speaking men, indicating that high prevalence of social capital may promote health. Finally, the present thesis also discussed the issue of methodological challenges faced with when analyzing social capital and health. It was suggested that certain components of social capital such as bonding and bridging social capital may be more relevant than structural and cognitive components when investigating social capital among the two language groups in Finland. The results concerning the oldest old indicated that the structural aspects of social capital probably reflect current living conditions, whereas cognitive social capital reflects attitudes and traits often acquired decades earlier. This is interpreted as an indication of the fact that structural and cognitive social capital are closely related yet empirically two distinctive concepts. Taken together, some components of social capital may be more relevant to study than others depending on which population group and age group is under study. The results also implied that the choice of cut-off point of dichotomization of selfrated health has an impact on the estimated effects of the explanatory variables. When the whole age interval, 35-64 years, was analyzed with logistic regression techniques the choice of cut-off point did not matter for the estimated effects of marital status and educational level. The results changed, however, when the age interval was divided into three shorter intervals. If self-rated health is explored using wide age intervals that do not account for age-dependent covariates there is a risk of drawing misleading conclusions. In conclusion, the results presented in the thesis suggest that the uneven distribution of social capital observed between the two language groups in Finland are of importance when trying to further understand health inequalities that exist between Swedish- and Finnish-speakers in Finland. Although social capital seemed to be relevant to the understanding of health among the oldest old, the meaning of social capital is probably different compared to a less vulnerable age group. This should be noticed in future empirical research. In the present thesis, it was shown that the relationship between social capital and health is complex and multidimensional. Different aspects of social capital seem to be important for different aspects of health. This reduces the possibility to generalize the results and to recommend general policy implementations in this area. An increased methodological awareness regarding social capital as well as health are called for in order to further understand the cfomplex association between them. However, based on the present data and findings social capital is associated with health. To understand individual health one must also consider social aspects of the individuals’ environment such as social capital.

Associations between alexithymia and mental well-being in adolescents

Nuorten tunneilmaisun yhteys psyykkiseen oireiluun Aleksitymialla tarkoitetaan persoonallisuuden piirteistöä, jolle on tyypillistä heikko kyky tunnistaa ja ilmaista tunteita sekä vähäinen mielikuvitus ja konkreettinen, ulkokohtainen ajattelutapa. Tämän tutkimuksen tarkoituksena on tarkastella aleksitymian yhteyttä psyykkiseen oireiluun nuorilla sekä tutkia aleksitymian kehittymiselle altistavia yksilöllisiä lapsuudenaikaisia tekijöitä. Tutkimusaineisto koostui aiempaan nuorten syömishäiriöoireilua tarkastelevaan tutkimukseen osallistuneista nuorista (n = 320) ja heille satunnaisotannalla poimituista verrokeista (n = 640). Seurantakyselyssä käytettiin vastaajan itsensä täytettäviä mittareita ja aineisto kerättiin postikyselynä. Yhteensä 729 henkilöä (78 %) palautti lomakkeen täytettynä, muodostaen näin lopullisen tutkimusaineiston. Tyttöjä vastanneista oli 74 % ja poikia 26 %. Aineiston keski-ikä oli 19 vuotta tämän tutkimuksen aikaan. Aineistosta oli käytettävissä neuvolatiedot syntymästä lähtien. Tutkimusaineistossa todettiin aleksitymian yleisyydeksi tytöillä 8,2 % ja pojilla 8,5 %. Sukupuolten välillä ei todettu eroa 20-osioisella Toronto Alexithymia Scale-kyselyllä (TAS-20) pistemäärissä (tytöillä 44.7 ja pojilla 46.0). Syömishäiriöoireiden todettiin olevan yleisempiä aleksityymisillä nuorilla verrattuna ei-aleksityymisiin. Syömishäiriöoireita mitattiin SCOFF-mittarilla (“Sick”, “Control”, “One”, “Fat”, “Food”). Aleksityymisten nuorten keskimääräinen SCOFF-pistemäärä oli merkitsevästi korkeampi kuin ei-aleksityymisten ja SCOFF-positiivisten (pistemäärä vähintään 2) osuus oli aleksityymisten ryhmässä kolminkertainen ei-aleksityymisten ryhmään verrattuna. Myös ahdistuneisuuden todettiin olevan yhteydessä aleksitymiaan nuorilla. Ahdistuneisuutta mitattiin State-Trait Anxiety Inventory-mittarilla (STAI) ja lisäksi mitattiin masennusoireita ja alkoholinkäyttöä. Aleksityymisten nuorten STAI-pisteet olivat merkitsevästi korkeammat kuin eialeksityymisten. Ahdistuneet aleksityymiset nuoret olivat myös yleisemmin masentuneita ja käyttivät runsaammin alkoholia kuin yhtä ahdistuneet ei-aleksityymiset nuoret. Tutkimuksessa selvitettiin aleksitymian yhteyttä sosiaaliseen tukeen sekä koettuun vanhempien hoivaan ja ylisuojelevaisuuteen. Käytetyt mittarit olivat Multidimensional Scale of Perceived Social Support ja Parental Bonding Instrument. Aleksitymia oli merkitsevästi yhteydessä sekä heikompaan koettuun sosiaaliseen tukeen – erityisesti ystäviltä saatavaan − että korkeampaan vanhempien ylisuojelevaisuuteen. Tutkimuksessa käytettiin 5-vuotisneuvolatarkastuksen tietoja sen arviointiin, mitkä kehitykselliset tekijät saattavat olla yhteydessä aleksitymian ilmenemiseen. Puheenkehityksen ongelmien todettiin olevan miehillä selvästi yhteydessä aleksitymiaan. Tutkimuksen perusteella aleksityymisillä nuorilla esiintyy ei-aleksityymisiin ikätovereihin verrattuna selvästi yleisemmin psyykkisiä oireita. Koska aleksitymia heikentää hoitovastetta todennäköisesti myös nuorilla, tulisi aleksitymian mahdollisuus selvittää tehokkaasti psyykkisesti oireilevilla nuorilla. Lisääntyvä tutkimustieto aleksitymian kehittymisestä mahdollistaa riskitapausten varhaisemman tunnistamisen ja tilanteeseen puuttumisen.

Prevalence of Anxiety and Depression among Medical Students

ABSTRACT Background Medical students are a vulnerable population to develop depression and anxiety disorders. Objective To estimate the prevalence and associated factors of anxiety and depression among medical students. Methods A cross-sectional study with a random sample (n = 346) of medical students at a Brazilian university was performed. The Beck Depression Anxiety Inventory was used to measure anxiety and depression levels. Crude and adjusted analyses were performed using Poisson regression. Results The prevalence of anxiety was 35.5% and depression was 32.8%. The prevalence of anxiety and depression was 14% higher and 16% higher among women (p = 0.025 and p = 0.006, respectively). Students whose parents were not physicians reported 23% higher prevalence of anxiety (p = 0.006), and those who had physician parents reported 29% higher prevalence of depression (p = 0.034). Those who always or often felt pushed by their parents showed 22% higher prevalence of anxiety (p =.006) and 19% higher depression (p = 0.016). Students who had concerns over the future had 15% higher prevalence of depression (p = 0.017). Conclusion The prevalence of anxiety and depressive symptoms was higher than the average found in the general population.

Personality and Depression

The aim of this study was to illustrate the associations of personality variables and depression. The first study population consisted of 50 patients with DSM-IV defined major depressive disorder. Subjects were randomized to receive either fluoxetine medication or short-term psychodynamic psychotherapy. The Hamilton Depression Rating Scale was completed at the baseline and in the follow-up at four months. Baseline mature defense style measured with the Defense Style Questionnaire predicted favourable outcome in the fluoxetine treatment group, whereas no associations were found in psychotherapy group. The Psychological Mindedness Scale scores were not predictive for recovery in patients receiving psychotherapy or medication. The Psychological Mindedness Scale seems not to be useful in selecting optimal treatment in major depressive disorder. Harm Avoidance measured with the Temperament and Character Inventory associated with the baseline severity of the depressive state. In the fluoxetine treatment group high Reward Dependence, high Self-Directedness and high Cooperativeness were predictive for more severe depression in the four months follow-up, whereas no associations were found in the psychotherapy treatment group. It is possible that the result reflects the differences in the placebo response. The second data were derived from the Finnish Public Sector Study. These prospective studies with four years follow-up focused on the predictive value of optimism and pessimism, first, to work disability with a diagnosis of depression lasting at least 90 days and returning to work (N= 38214) , and second, to the likelihood of initiating antidepressant medication treatment lasting at least 100 days and ending the treatment (N= 29930). Results show that low optimism associates with the elevated risk of work disability and higher likelihood of antidepressant use. High pessimism associated with higher likelihood starting at least 100 days antidepressant medication and not stopping medication during the follow up. High pessimism did not seem to predict the entering to depression related work disability, but in the case of disability period it associated with the lower likelihood of returning to work. The thesis shows that personality features play a role as a vulnerability factor, and influence the onset and course of depression. Taking these factors into account more than is currently done may increase the possibilities to enhance the treatment results in depression.

Fractures in older people - incidence, predictors and consequences

In older populations, fractures are common and the consequences of fractures may be serious both for an individual and for society. However, information is scarce about the incidence, predictors and consequences of fractures in population-based unselected cohorts including both men and women and a long follow-up. The objective of this study was to analyse the incidence and predictors of fractures as well as functional decline and excess mortality due to fractures, among 482 men and 695 women aged 65 or older in the municipality of Lieto, Finland from 1991 until 2002. In analyses, Poisson’s, Cox proportional Hazards and Cumulative Logistic regression models were used for the control of several confounding variables. During the 12-year follow-up with a total of 10 040 person-years (PY), 307 (26%) persons sustained altogether 425 fractures of which 77% were sustained by women. The total incidence of fractures was 53.4 per 1000 PY (95% confidence intervals [95% CI]: 47.9 - 59.5) in women and 24.9 per 1000 PY (95% CI: 20.4 - 30.4) in men. The incidence rates of fractures at any sites and hip fractures were associated with increasing age. No significant changes in the ageadjusted incidence rates of fractures were found in either gender during the 12-year follow-up. The predictors of fractures varied by gender. In multivariate analyses, reduced handgrip strength and body mass index (BMI) lower than 30 in women and a large number of depressive symptoms in men were independent predictors of fractures. A compression fracture in one or more thoracic or upper lumbar vertebras on chest radiography at baseline was associated with subsequent fractures in both genders. Lower body fractures independently predicted both short- (0-2 years) and long-term (up to 8 years) functional decline in mobility and activities of daily living (ADL) performance during the 8-year follow-up. Upper body fractures predicted decline in ADL performance during longterm follow-up. In the 12-year follow-up, hip fractures in men (Hazard Ratio [HR] 8.1, 95% CI: 4.4-14.9) and in women (HR 3.0, 95% CI: 1.9-4.9), and fractures at the proximal humerus in men (HR 5.4, 95% CI: 1.6-17.7) were independently associated with excess mortality. In addition, leisure time inactivity in physical exercise predicted independently both functional decline and excess mortality. Fractures are common among older people posing serious individual consequences. Further studies about the effectiveness of preventing falls and fractures as well as improving care and rehabilitation after fractures are needed.

Cognitive Functions After Traumatic Brain Injury. A 30-year Follow-up Study

Many cognitive deficits after TBI (traumatic brain injury) are well known, such as memory and concentration problems, as well as reduced information-processing speed. What happens to patients and cognitive functioning after immediate recovery is poorly known. Cognitive functioning is flexible and may be influenced by genetic, psychological and environmental factors decades after TBI. The general aim of this thesis was to describe the long-term cognitive course after TBI, to find variables that may contribute to it, and how the cognitive functions after TBI are associated with specific medical factors and reduced survival. The original study group consisted of 192 patients with TBI who were originally assessed with the Mild Deterioration Battery (MDB) on average two years after the injury, during the years 1966 – 1972. During a 30-year follow-up, we studied the risks for reduced survival, and the mortality of the patients was compared with the general population using the Standardized Mortality Ratio (SMR). Sixty-one patients were re-assessed during 1998-2000. These patients were evaluated with the MDB, computerized testing, and with various other neuropsychological methods for attention and executive functions. Apolipoprotein-E (ApoE) genotyping and magnetic resonance imaging (MRI) based on volumetric analysis of the hippocampus and lateral ventricles were performed. Depressive symptoms were evaluated with the short form of the Beck depression inventory. The cognitive performance at follow-up was compared with a control group that was similar to the study group in regard to age and education. The cognitive outcome of the patients with TBI varied after three decades. The majority of the patients showed a decline in their cognitive level, the rest either improved or stayed at the same level. Male gender and higher age at injury were significant risk factors for the decline. Whereas most cognitive domains declined during the follow-up, semantic memory behaved in the opposite way, showing recovery after TBI. In the follow-up assessment, the memory decline and impairments in the set-shifting domain of executive functions were associated with MRI-volumetric measures, whereas reduction in information-processing speed was not associated with the MRI measures. The presence of local contusions was only weakly associated with cognitive functions. Only few cognitive methods for attention were capable of discriminating TBI patients with and without depressive symptoms. On the other hand, most complex attentional tests were sensitive enough to discriminate TBI patients (non-depressive) from controls. This means that complex attention functions, mediated by the frontal lobes, are relatively independent of depressive symptoms post-TBI. The presence of ApoE4 was associated with different kinds of memory processes including verbal and visual episodic memory, semantic memory and verbal working memory, depending on the length of time since TBI. Many other cognitive processes were not affected by the presence of ApoE4. Age at injury and poor vocational outcome were independent risk factors for reduced survival in the multivariate analysis. Late mortality was higher among younger subjects (age < 40 years at death) compared with the general population which should be borne in mind when assessing the need for rehabilitation services and long-term follow-up after TBI.

Uusintamurtumien ehkäisy kaatumisen aiheuttaman yläraajamurtuman kokeneilla yli 50-vuotiailla henkilöillä

Tarkoitus: Tarkoituksena oli selvittää murtumien tehostetun ehkäisyohjelman vaikutuksia yläraajamurtuman saaneiden yli 50-vuotiaiden henkilöiden elämäntapoihin, murtumien riskitekijöihin, kaatumisiin, kaatumisvammoihin ja elämänlaatuun. Aineisto: 219 yli 50-vuotiasta kotona asuvaa, kaatumisen seurauksena yläraajamurtuman saanutta henkilöä satunnaistettiin koe- (n = 105) ja kontrolliryhmiin (n = 114). Menetelmä: Koeohjelma sisälsi yksilöllisen, yhdessä lääkärin, terveydenhoitajan ja tutkittavan kanssa laaditun hoito- ja kuntoutussuunnitelman sekä kutsun murtumien ehkäisyn koulutusohjelmaan. Kontrolliryhmän tutkittavat saivat kehotuksen hakeutua murtumahoitajan ohjaukseen. Seuranta-aika oli 14 kuukautta. Tulokset analysoitiin ryhmissä tapahtuneina muutoksina alkuja loppumittausten välillä sekä ryhmien välisenä erona muutoksissa. Tulokset: Keskimääräinen luun tiheys lannerangassa lisääntyi koeryhmässä (p<0,001) ja kontrolliryhmässä (p = 0,038), ryhmien välinen ero ei ollut tilastollisesti merkitsevä (p = 0,134). Reisiluun kaulassa luun tiheys ei muuttunut kummassakaan ryhmässä. Päivittäinen kalsiumin saanti lisääntyi koeryhmässä keskimäärin 167 mg (p<0,001) ja kontrolliryhmässä 30 mg (p = 0,475), ryhmien välinen ero oli tilastollisesti merkitsevä (p = 0,031). Kala-ateriat ja päivittäinen D-vitamiinilisä sekä kenkien liukuesteiden säännöllinen käyttö liukkaalla lisääntyivät molemmissa ryhmissä, mutta ryhmien välillä ei ollut eroa. Viiteen tuolilta nousukertaan käytetty aika vähentyi koeryhmässä keskimäärin 0,49 sekuntia (p = 0,185) ja lisääntyi kontrolliryhmässä 0,39 (p = 0,475), ero ryhmien välillä oli tilastollisesti merkitsevä (p = 0,02). Kymmenen metrin kävelyssä ei tapahtunut tulosten keskiarvossa muutoksia kummassakaan ryhmässä. Ortostatismi vähentyi kontrolliryhmässä (p = 0,049), ja masentuneisuus vähentyi koeryhmässä (p = 0,041), mutta ryhmien välillä ei näissä ollut merkitsevää eroa. Osteoporoosilääkkeiden käyttö lisääntyi molemmissa ryhmissä, ryhmien välillä ei ollut eroa. Alkoholin käytössä oli vähäisiä mutta ei merkittäviä muutoksia. Muissa testatuissa muuttujissa, kuten liikunnan viikoittainen määrä, tupakointi, näkökyky, tasapaino ja elämänlaatu, ei ollut merkitseviä muutoksia ryhmissä tai ryhmien välillä. Kaatumisten (koeryhmä 33, kontrolliryhmä 35) ja murtumien (koeryhmä 5 ja kontrolliryhmä 3) määrissä ei myöskään ollut merkitseviä eroja ryhmien välillä. Johtopäätökset: Noin neljällä viidestä kaatumisen seurauksena yläraajamurtuman saaneista, yli 50 vuotta täyttäneistä henkilöistä oli alentunut luun tiheys, ja noin joka toisella oli lisääntynyt kaatumisriski. Kaatumisen riskitekijöiden kliiniset mittaukset olivat nopeita toteuttaa ja auttoivat ehkäisytoimenpiteiden suunnittelussa. Murtuman saaneet olivat motivoituneita murtumien riskitekijöiden selvittämiseen ja myös toteuttamaan annettua lääkehoitoa. Elämäntavoissa helpoimmin toteutuivat muutokset ruokailutottumuksissa. Liikuntatottumuksien muuttaminen sen sijaan onnistui melko huonosti. Ryhmien välillä oli merkitsevä ero ainoastaan kalsiumin päivittäisessä käytössä ja tuolilta nousutestissä. Murtumariskien tunnistaminen, niiden syiden selvittäminen ja toimenpiteiden käynnistäminen riskien vähentämiseksi tulisi kuulua jokaisen pienienergisen murtuman saaneen potilaan kokonaisvaltaiseen hyvään hoitoon.

Kaatumisvaaraa lisäävät lääkkeet; Porissa toteutettu iäkkäiden monitekijäinen kaatumisten ehkäisy

Kaatumiset ovat ikääntyvien yleisimpiä tapaturmia. Niiden seuraukset voivat olla vakavia. Yksilöllisesti toteutetut ehkäisyohjelmat ovat vähentäneet kaatumisvaarassa olevien iäkkäiden kaatumisia. Psyykenlääkkeiden on osoitettu lisäävän kaatumisia ja murtumia. Niiden lopettaminen on vähentänyt kaatumisvaaraa. Monitekijäiset ehkäisyohjelmat kuvaavat harvoin psyykenlääkkeiden vähentämisen menetelmiä ja tuloksia. Satunnaistettuun, kontrolloituun kaatumisten moneen vaaratekijään kohdistettuun ehkäisytutkimukseen osallistui 591 porilaista. Tässä tutkimuksessa selvitettiin kotona asuvien 65 vuotta täyttäneiden, tutkimusta edeltäneiden 12 kuukauden aikana ainakin kerran kaatuneiden henkilöiden psyykenlääkkeiden käyttö, niiden vähentämisen onnistuminen ja vaikutus sekä ehkäisyohjelman merkitys kaatumisten ilmaantumiseen. Lisäksi tutkittiin kaatumisvamman takia hoitoon hakeutuneiden kaatumisvaaratekijöiden tunnistamista ja uusien kaatumisten ja murtumien ehkäisemiseksi suunniteltuja toimenpiteitä perusterveydenhuollossa ja erikoissairaanhoidossa. Joka neljäs osallistuja käytti säännöllisesti psyykenlääkkeitä. Kertaneuvonta niiden vähentämisestä, johon sisältyi kirjalliset ohjeet lääkemuutoksista ja luento lääkkeiden vaikutuksista kaatumisvaaraan, vähensi säännöllisten psyykenlääkkeiden käyttäjien lukumäärää 22 % ja bentsodiatsepiineja tai niiden kaltaisia lääkkeitä käyttävien lukumäärää 35%. Kaatumisen vuoksi terveyskeskukseen ja keskussairaalaan hakeutuneiden iäkkäiden kaatumisvaaratekijöiden selvittelyyn ja uusien kaatumisten tai murtumien ehkäisyyn kiinnitettiin erittäin vähän huomiota. Toimenpiteet keskittyivät syntyneiden vammojen tutkimiseen ja hoitoon. Monitekijäinen ehkäisyinterventio vähensi masentuneiden ja monikaatuilijoiden kaatumisia, mutta ei kaikkien osallistujien kaatumisten määrää 12 kuukauden ehkäisyohjelman aikana. Erityisesti bentsodiatsepiiniryhmän lääkkeitä käyttävät verrokkiryhmän jäsenet joutuivat herkemmin kaatumisen vuoksi lääkärinhoitoon ehkäisyohjelman jälkeisen vuoden aikana kuin nämä lääkkeet lopettaneet koeryhmän jäsenet. Johtopäätöksenä voidaan todeta, että psyykenlääkkeiden tunnistaminen kaatumisten vaaratekijäksi oli puutteellista. Niiden käyttöön tulisi kiinnittää enemmän huomiota, ja niiden käyttö tulisi purkaa aina, kun se on lääketieteellisesti mahdollista. Kaatumisten ehkäisy pitäisi kuulua terveydenhoitoon. Kohdennettuja ehkäisyohjelmia erilaisille kaatumisvaarassa oleville iäkkäille tulee kehittää edelleen.

Eating disorders, weight perception, and dieting in adolescence

Background: Eating disorders are serious psychiatric disorders, which usually have their onset in adolescence. Body dissatisfaction and dieting, both common among adolescents, are recognised risk factors for eating disorders. The aim of the present study was to assess the prevalence of eating disorders in the general adolescent population, assess the risk of developing eating disorders in subgroups of dieters, and analyse longitudinal concomitants of incorrect weight perception. Method: A prospective follow-up study on 595 adolescents, aged 15 at baseline, was conducted in western Finland. The study comprised questionnaires directed at the whole study population and subsequent personal interviews with adolescents found to be screen-positive for eating disorders, at both baseline and three-year follow-up. Results: The lifetime prevalence rates for 18 year old females were 2.6 % for anorexia nervosa, 0.4 for bulimia nervosa, and 9.0 % for eating disorder not otherwise specified (EDNOS). No prevalent case of DSM-IV eating disorders was found among the male participants. Eating disorders, as well as depressive symptoms, social anxiety, and low self-esteem, was more prevalent among females who perceived themselves as being overweight, despite being normal or underweight, when compared to females with a correct weight perception. An incorrect weight perception was associated in males with social anxiety. Female adolescents dieting due to psychological distress, rather than vanity or overweight, had a fifteen-fold risk of developing an eating disorder. Conclusions: Eating disorders are common among female adolescents, and adolescents choosing to diet due to psychological distress show a markedly increased risk of developing an eating disorder. Promotion of general well-being as well as the prevention of body dissatisfaction and misdirected dieting, accompanied by early detection and proper treatment of eating disorders, is needed to reduce the incidence of and facilitate recovery in adolescents suffering from eating disorders.

Corpo estranho no ceco retirado por colonoscopia

The foreign body ingestion ocurrs often with children, olds, psychiatrics patients, prisoners or after excessive alcoholic ingestion. Most of foreign bodies (80-90%) passes spontaneously, 10 a 20% have to be removed by endoscopy and only one per cent (1%) needs to be removed by surgery. The authors report a case of a 49-year-old woman who swallowed a needle which impacted in cecum. The patient had psychosis maniac-depressive and swallowed the foreign body aiming self-damage. The presence of foreign body in cecum is rare because of physiologic straitments in the gastrointestinal tract. The ingestion of needle corresponds six percent (6%) of swallowed objects aiming self-damage. Colonoscopy served for localization the foreign body and its withdrawal with success. Colonoscopy for removing foreign bodies is a safe and cheap procedure.

Impact of bariatric surgery on depression and anxiety symptons, bulimic behaviors and quality of life

OBJECTIVE: To assess psychiatric symptoms, substance use, quality of life and eating behavior of patients undergoing bariatric surgery before and after the procedure.METHODS: We conducted a prospective longitudinal study of 32 women undergoing bariatric surgery. To obtain data, the patients answered specific, self-administered questionnaires.RESULTS: We observed a reduction in depressive and anxious symptoms and also in bulimic behavior, as well as an improved quality of life in the physical, psychological and environmental domains. There was also a decrease in use of antidepressants and appetite suppressants, but the surgery was not a cessation factor in smoking and / or alcoholism.CONCLUSION: a decrease in psychiatric symptoms was observed after bariatric surgery, as well as the reduction in the use of psychoactive substances. In addition, there was an improvement in quality of life after surgical treatment of obesity.

Depression with postpartum onset: a prospective cohort study in women undergoing elective cesarean section in Brasilia, Brazil

PURPOSE: It was to determine the prevalence of depressive symptoms in a sample of puerperal women from Brasília, Brazil, distinguishing cases with onset after delivery from those already present during pregnancy. METHODS: A prospective cohort study with convenience sampling of patients submitted to elective cesarean section at two private hospitals. As an instrument for assessing depressive symptoms, the Edinburgh Postnatal Depression Scale with cutoff >13 was applied shortly before delivery and four to eight weeks after childbirth. RESULTS: Among the 107 women who completed the study, 11 (10.3%) had significant depressive symptoms during pregnancy and 12 (11.2%) during the postpartum period. Among the 12 patients with postpartum symptoms, 6 had symptoms during pregnancy, so that 5.6% of the sample had postpartum onset of depression. The higher overall frequency of depression was significantly among single women than among married women (p=0.04), a fact mainly due to a higher frequency of single women experiencing persistent depressive symptoms both before and after delivery (p=0.002). The risk of depression was not influenced by age, parity or educational level. CONCLUSION: Women with depression identified during the postpartum period comprise a heterogeneous group, in which symptoms may have started before pregnancy, during pregnancy or after childbirth. In this sample, half of the postpartum depression cases already presented symptoms during late pregnancy. Since depression can arise before and after childbirth, it may have different etiologies and, therefore, a different response to treatment, a possibility that should be considered by clinicians and researchers.

Ethological activities, ruminal parameters and weight gain of calves supplemented with different amounts of sodium chloride

The daily weight gain, behavioral activities (grazing, ruminating and water consumption) and the number of rumen protozoa, pH, NH3, and the osmolarity of rumen fluid was evaluated for four groups of six calves HPB/Zebu submitted to daily intake of 15, 30, 60 and 90g of NaCl during 135 days (9th Jan. to 24th May 2008).Throughout the experimental period the calves were in perfect health condition and did not show any signs suggestive of chronic sodium poisoning. There was no significant difference in average daily gain of the calves as the intake of NaCl increased. No significant behavioral changes were observed in the activities of grazing and rumination. However, there was a noticeable change in the frequency of water consumption in the calves that ingested 90g/d of NaCl; they went more often to the trough and drank more water than the group that ingested only 15g sodium chloride/d. The osmolarity of ruminal liquid was higher in the group of calves fed 90g of NaCl/d. The pH, NH3 concentration and number of rumen protozoa was within the normal range.

Smoking and psychiatric disorders: a comorbidity survey

Epidemiological and clinical studies have shown a positive correlation between smoking and psychiatric disorders. To investigate the prevalence of cigarette smoking, 277 psychiatric outpatients with anxiety or depressive disorders (DSM-IV) answered a self-evaluation questionnaire about smoking behavior and were compared with a group of 68 control subjects. The diagnoses (N = 262) were: 30.2% (N = 79) major depressive disorder, 23.3% (N = 61) panic disorder, 15.6% (N = 41) social anxiety disorder, 7.3% (N = 19) other anxiety disorders, and 23.7% (N = 62) comorbidity disorders. Among them, 26.3% (N = 69) were smokers, 23.7% (N = 62) were former smokers and 50.0% (N = 131) were nonsmokers. The prevalence of nicotine dependence among the smokers was 59.0% (DSM-IV). The frequency of cigarette smoking did not show any significant difference among the five classes of diagnosis. The social anxiety disorder patients were the heaviest smokers (75.0%), with more unsuccessful attempts to stop smoking (89.0%). The frequency of former smokers was significantly higher among older subjects and nonsmokers were significantly younger (c² = 9.13, d.f. = 2, P = 0.01). Our data present some clinical implications suggesting that in our psychiatric outpatient sample with anxiety disorder, major depression and comorbidity (anxiety disorder and major depression), the frequency of cigarette smoking did not differ from the frequency found in the control group or in general population studies. Some specific features of our population (outpatients, anxiety and depressive disorders) might be responsible for these results.

Headache complaints associated with psychiatric comorbidity in a population-based sample

The objective of the present study was to determine the frequency at which people complain of any type of headache, and its relationship with sociodemographic characteristics and psychiatric comorbidity in São Paulo, Brazil. A three-step cluster sampling method was used to select 1,464 subjects aged 18 years or older. They were mainly from families of middle and upper socioeconomic levels living in the catchment area of Instituto de Psiquiatria. However, this area also contains some slums and shantytowns. The subjects were interviewed using the Brazilian version of the Composite International Diagnostic Interview version 1.1. (CIDI 1.1) by a lay trained interviewer. Answers to CIDI 1.1 questions allowed us to classify people according to their psychiatric condition and their headaches based on their own ideas about the nature of their illness. The lifetime prevalence of "a lot of problems with" headache was 37.4% (76.2% of which were attributed to use of medicines, drugs/alcohol, physical illness or trauma, and 23.8% attributed to nervousness, tension or mental illness). The odds ratio (OR) for headache among participants with "nervousness, tension or mental illness" was elevated for depressive episodes (OR, 2.1; 95%CI, 1.4-3.4), dysthymia (OR, 3.4; 95%CI, 1.6-7.4) and generalized anxiety disorder (OR, 4.3; 95%CI, 2.1-8.6), when compared with patients without headache. For "a lot of problems with" headaches attributed to medicines, drugs/alcohol, physical illness or trauma, the risk was also increased for dysthymia but not for generalized anxiety disorder. These data show a high association between headache and chronic psychiatric disorders in this Brazilian population sample.
