Background This study sought to assess the diet quality of individuals living with HIV/AIDS who were receiving antiretroviral therapy in Sao Paulo Brazil,. Methods This cross-sectional study involved 56 HIV-infected adults. Demographic and anthropometric data were collected, and diet quality was measured using the Healthy Eating Index (HEI), modified for Brazilians, which included ten components: adequacy of intake of six different food groups, total fat, cholesterol, dietary fibre and dietary variety. Results Among the individuals assessed, 64.3% of the participants had a diet needing improvement, while 8.7% had a poor diet. The overall HEI score was 68.3 points (SD = 14.9). Mean scores were low for fruits, vegetables, dairy products and dietary fibre; and high for meats and eggs, total fat and cholesterol. The overall HEI score was higher among individuals who were not overweight (P = 0.003), who were also more likely to achieve dietary goals for dairy products (P = 0.039) and grains (P = 0.005). Conclusion Most of these adults living with HIV/AIDS had diets that required improvement, and being overweight was associated with poorer diet quality. Nutritional interventions aimed at maintaining healthy body weight and diet should be taken into account in caring for HIV-infected people.

Background Dietary calcium intake has been described as being a negative contributor to adiposity. In adolescents, this relationship is not well established. The objectives of the present study were to compare the calcium intake of normal-weight and obese adolescents and to evaluate its relationship with adiposity and insulin resistance. Methods A cross-sectional analysis of 96 post-pubertal adolescents; 47 normal weight and 49 obese, mean age 16.6 (SD +/- 1.3) years. Body composition was assessed by dual-energy X-ray absorptiometry. Dietary intake was evaluated using a 3-day dietary record. The biochemical evaluation comprised the measurements of serum lipids, lipoproteins, glucose and insulin. Insulin resistance was calculated using the Homeostasis Model Assessment of Insulin resistance (HOMA-IR). Results The mean calcium intake, adjusted for energy, was lower in obese adolescents, 585.2 (+/- 249.9) mg, than in normal weight adolescents, 692.1 (+/- 199.5) mg. Only 4% of adolescents had an adequate intake of calcium. Calcium intake was inversely associated with body trunk fat, insulin and HOMA-IR in the obese group. The quartile analysis of calcium intake provided evidence that girls in the highest quartile had decreased adiposity and insulin resistance. Conclusions This study showed a negative relationship between calcium intake and body fat and insulin resistance, mainly in obese girls, and demonstrates the importance of an increased dietary calcium intake.

We aimed to evaluate the classification of arm circumference (AC) in pre-school children by using National Center for Health Statistics (NCHS/CDC-2000) and World Health Organization (WHO-2006) references. We evaluated 205 children: weight, height and AC were assessed and the body mass index (BMI) was calculated. The BMI values were classified into Z-scores by the WHO referential. The AC was classified into Z-cores by two references, comparing the whole-sample value and among groups (tercis) of BMI Z-score. The correlation was also evaluated between differences of AC with BMI Z-score. The WHO referential classified the AC in Z-scores greater than the NCHS/CDC, which is more specific and less sensitive than the NCHS/CDC for lean children and at the same time more sensitive and less specific for children with overweight. In conclusion, a significant difference in the AC classification occurs according to the referential used.

The objective of the present study was to validate a recently reported synergistic effect between variants located in the leptin receptor (LEPR) gene and in the beta-2 adrenergic receptor (ADRB2) gene on the risk of overweight/obesity. We studied a middle-aged/ elderly sample of 4,193 nondiabetic Japanese subjects stratified according gender (1,911 women and 2,282 men). The LEPR Gln223Arg (rs1137101) variant as well as both ADRB2 Arg16Gly (rs1042713) and Gln27Glu (rs1042714) polymorphisms were analyzed. The primary outcome was the risk of overweight/obesity defined as BMI >= 25 kg/m(2), whereas secondary outcomes included the risk of a BMI >= 27 kg/m(2) and BMI as a continuous variable. None of the studied polymorphisms showed statistically significant individual effects, regardless of the group or phenotype studied. Haplotype analysis also did not disclose any associations of ADRB2 polymorphisms with BMI. However, dimensionality reduction-based models confirmed significant interactions among the investigated variants for BMI as a continuous variable as well as for the risk of obesity defined as BMI >= 27 kg/m(2). All disclosed interactions were found in men only. Our results provide external validation for a male specific ADRB2-LEPR interaction effect on the risk of overweight/obesity, but indicate that effect sizes associated with these interactions may be smaller in the population studied.

We investigated whether variants in major candidate genes for food intake and body weight regulation contribute to obesity-related traits under a multilocus perspective. We studied 375 Brazilian subjects from partially isolated African-derived populations (quilombos). Seven variants displaying conflicting results in previous reports and supposedly implicated in the susceptibility of obesity-related phenotypes were investigated: beta(2)-adrenergic receptor (ADRB2) (Arg16Gly), insulin induced gene 2 (INSIG2) (rs7566605), leptin (LEP) (A19G), LEP receptor (LEPR) (Gln223Arg), perilipin (PLIN) (6209T > C), peroxisome proliferator-activated receptor-gamma (PPARG) (Pro12Ala), and resistin (RETN) (-420C > G). Regression models as well as generalized multifactor dimensionality reduction (GMDR) were employed to test the contribution of individual effects and higher-order interactions to BMI and waist-hip ratio (WHR) variation and risk of overweight/obesity. The best multilocus association signal identified in the quilombos was further examined in an independent sample of 334 Brazilian subjects of European ancestry. In quilombos, only the PPARG polymorphism displayed significant individual effects (WHR variation, P = 0.028). No association was observed either with the risk of overweight/obesity (BMI >= 25 kg/m(2)), risk of obesity alone (BMI >= 30 kg/m(2)) or BMI variation. However, GMDR analyses revealed an interaction between the LEPR and ADRB2 polymorphisms (P = 0.009) as well as a third-order effect involving the latter two variants plus INSIG2 (P = 0.034) with overweight/obesity. Assessment of the LEPR-ADRB2 interaction in the second sample indicated a marginally significant association (P = 0.0724), which was further verified to be limited to men (P = 0.0118). Together, our findings suggest evidence for a two-locus interaction between the LEPR Gln223Arg and ADRB2 Arg16Gly variants in the risk of overweight/obesity, and highlight further the importance of multilocus effects in the genetic component of obesity.

Syfte: Att ta reda på vilka uppfattningar föräldrar har kring deras barns övervikt och hur vårdpersonal ser på omvårdnaden av barn med övervikt. Samt att belysa vilket samband som finns mellan en osund livsstil och barn med övervikt. Design: En systematisk litteraturstudie med deskriptiv ansats. Inkluderade artiklarna i studien var både kvantitativa och kvalitativa och kommer från databaserna Pubmed och Cinahl. Resultat: Stillasittande aktiviteter ökar risken för övervikt medan deltagande i någon fysisk aktivitet dagligen minskar risken för övervikt. Det finns en signifikant betydelse mellan övervikt och barn som idrottar mindre än tre timmar per vecka. Barn som inte äter frukost löper 50 % större risk att bli överviktig än de barn som äter frukost. Att hoppa över skollunchen är direkt relaterat till övervikt. När föräldrar söker hjälp av sjukvården för sitt överviktiga barn, har de redan prövat att ändra kosten och uppmuntra till fysisk aktivitet hemma. När föräldrarna söker hjälp är några av deras uppfattningar att sjukvården inte vet vad de ska göra för att hjälpa barnen med övervikt eller att sjukvården är hjälpsamma. Sjuksköterskorna kände sig inte tillräckligt kompetenta till att rekommendera viktminskningsprogram och att det var svårt att ge sådana råd till föräldrarna Vårdpersonalen kände att det var viktigt att prata om kost, men att vissa mammor tyckte att ämnet var känsligt att prata om. Det som hjälpte i förebyggande arbete eller i behandling var att jobba i små steg med kortsiktiga mål.

I ett internationellt perspektiv har Sverige hög amningsfrekvens, men under 2000-talet har amningsfrekvensen sjunkit och stora regionala skillnader ses. Kvinnorna rekommenderas att helamma sex månader. Mödravårdcentralen (MVC) informerar om bröstmjölkens hälsoeffekter som till exempel att bröstmjölken skyddar barn mot allergier. Forskning visar att överviktiga och feta kvinnor har kortare amningsduration, men få studier behandlar svenska förhållanden. Syfte: Syfte med fördjupningsarbetet är att studera samband mellan mammans BMI relaterat till amningsduration och mammans skattning av barnets hälsa de tre första levnadsåren. Metod: Studien är en kvantitativ retrospektiv tvärsnittstudie. Data insamlades via enkäter, 418 deltagare inkluderades. Data har analyserats med Statistical Package for the Social Sciences (SPSS). För deskriptiv och jämförande analys har parametriska och icke-parametriska analyser genomförts. Resultat: De kvinnor som inte ammade skattade sitt barns hälsa sämre vid tre års ålder i jämförelse med kvinnor som ammat någon period. Vid tre års ålder skattade kvinnor med övervikt och fetma sitt barns hälsa sämre. Slutsats: Det är viktigt att kunna identifiera kvinnor som är behov av stöd för att initiera amning och kunna bidra till anpassat stöd till dem. AbstractSweden reports high duration of breastfeeding compared to international findings. During the last century, the frequency of breastfeeding duration has decreased in Sweden, with large regional differences. Recommendation for exclusive breastfeeding is six months. Midwives provide information about healthy benefits of breast milk, such as breast milk protecting baby´s against allergies. Research has presented associations between obesity and short duration of breastfeeding. However, there is a lack of knowledge regarding women in a Swedish context. Aim: To investigate the relation between mothers BMI, duration of breastfeeding and maternal valuation of the baby´s health during the first three year of life. Method: The study is a quantitative retrospective cross-sectional study. Data was collected through questionnaires, 418 participants were included. Data was analyzed using the SPSS. For descriptive and comparative analysis parametric and nonparamateric statistics have been used.Results: Women who did not breastfed perceived their baby´s health worse at three years compared with women who did breastfeed. Women with overweight and obesity also perceived the health of their three year old worse than the other maternal group. Conclusions: It´s important to identify women who need support to initiate breastfeeding and give them customized support.

The weight order – an analytical perspective This article is an outline of a critically oriented and empirically grounded theory of the weight order, as a complement to theories of more widely recognized and studied ordering systems. We 1) expose the weight orders “absent presence” in humanistic and social science-oriented research treating overweight and fatness as a personal or social problem, 2) outline the contours and characteristics of this specific ordering system, and 3) suggest a set of sensitizing concepts for analysis of this ordering system. Two primary forms of activity, maintaining order and putting in order, are analysed. The first is making thin people into order and overweight people into disorder, and thus maintains order in the weight order. The other, putting in order, covers different activities supposed to make sure that people keep their bodies thin or try to become thin. These ordering activities meet resistance when overweight people stop dieting and/or define overweight as a personal choice and themselves as good enough, or even healthy and beautiful. We call these forms of resistance alternative weight-doings.

Background: Despite the recommendations to continue the regime of healthy food and physical activity (PA) postpartum for women with previous gestational diabetes mellitus (GDM), the scientific evidence reveals that these recommendations may not be complied to. This study compared lifestyle and health status in women whose pregnancy was complicated by GDM with women who had a normal pregnancy and delivery. Methods: The inclusion criteria were women with GDM (ICD-10: O24.4 A and O24.4B) and women with uncomplicated pregnancy and delivery in 2005 (ICD-10: O80.0). A random sample of women fulfilling the criteria (n = 882) were identified from the Swedish Medical Birth Register. A questionnaire was sent by mail to eligible women approximately four years after the pregnancy. A total of 444 women (50.8%) agreed to participate, 111 diagnosed with GDM in their pregnancy and 333 with normal pregnancy/ delivery. Results: Women with previous GDM were significantly older, reported higher body weight and less PA before the index pregnancy. No major differences between the groups were noticed regarding lifestyle at the follow-up. Overall, few participants fulfilled the national recommendations of PA and diet. At the follow-up, 19 participants had developed diabetes, all with previous GDM. Women with previous GDM reported significantly poorer self-rated health (SRH), higher level of sick-leave and more often using medication on regular basis. However, a history of GDM or having overt diabetes mellitus showed no association with poorer SRH in the multivariate analysis. Irregular eating habits, no regular PA, overweight/obesity, and regular use of medication were associated with poorer SRH in all participants. Conclusions: Suboptimal levels of PA, and fruit and vegetable consumption were found in a sample of women with a history of GDM as well as for women with normal pregnancy approximately four years after index pregnancy. Women with previous GDM seem to increase their PA after childbirth, but still they perform their PA at lower intensity than women with a history of normal pregnancy. Having GDM at index pregnancy or being diagnosed with overt diabetes mellitus at follow-up did not demonstrate associations with poorer SRH four years after delivery.

The practice of bodily differentiation: Overweight and internet dating on the market of intimacy With the emergence of Internet dating, the procedure for choosing a partner has been radically changed. Given the initial invisibility of the body when Internet dating, one might presume that looks become less important when searching for partners online. Unfortunately, this is far from the truth. Based on twelve interviews with Internet daters of which six define themselves as overweight, the reproduction of bodily distinction in both mediated and direct communication is here being studied. A recurrent theme among the interviewees is the disappointment of the first date face to face. Ironically the importance of looks (or bodily capital) appears to be even more vital when dating on Internet than when building relationships “in real life”. Besides the disappointment of the first date in real life, the obese women in this study could also gather information of their value on the market of intimacy through being met by serious harassments and in exclusively being treated as sexual objects. Despite its strong association with the physical body, bodily capital can sometimes be difficult to distinguish from other forms of capital. From this point of view, the possibility of less repressive forms of intimacy is discussed.

Cathepsin S is a protease important in major histocompatibility complex (MHC) class II antigen presentation and also in degrading the extracellular matrix. Studies, most of them experimental, have shown that cathepsin S is involved in different pathological conditions such as obesity, inflammation, atherosclerosis, diabetes, and cancer. The overall hypothesis of this report is that high levels of circulating cathepsin S, is a biomarker that reflects pathology induced by inflammation and obesity. The overall aim of this report was to investigate possible associations between circulating cathepsin S, inflammation, glucometabolic disturbance, and its associated diseases in the community. As cathepsin S appears to be a novel risk marker for several pathological conditions, we also wanted to examine the effect of dietary intervention on circulating cathepsin S concentrations. This thesis is based on data from three community-based cohorts, the Uppsala longitudinal study of adult men (ULSAM), the prospective investigation of the vasculature in Uppsala seniors (PIVUS), and a post-hoc study from the randomized controlled NORDIET trial. In the first study, we identified a cross-sectional positive association between serum cathepsin S and two markers of cytokine-mediated inflammation, CRP and IL-6. These associations were similar in non-obese individuals. In longitudinal analyses, higher cathepsin S at baseline was associated with higher CRP and IL-6 levels after six years of follow-up. In the second study, we identified a cross-sectional association between increased serum levels of cathepsin S and reduced insulin sensitivity. These associations were similar in non-obese individuals. No significant association was observed between cathepsin S and insulin secretion. In longitudinal analysis, higher cathepsin S levels were associated with an increased risk of developing diabetes during the six-year follow-up. In the third study, we found that higher serum levels of cathepsin S were associated with increased mortality risk. Moreover, in the ULSAM cohort, serum cathepsin S was independently associated with cause-specific mortality from cardiovascular disease and cancer. In the fourth study, we identified that adherence to an ad libitum healthy Nordic diet for 6 weeks slightly decreased the levels of plasma cathepsin S in normal or marginally overweight individuals, relative to the control group. Changes in circulating cathepsin S concentrations were correlated with changes in body weight, LDL-C, and total cholesterol. Conclusion: This thesis shows that circulating cathepsin S is a biomarker that independently reflects inflammation, insulin resistance, the risk of developing diabetes, and mortality risk. Furthermore, a Nordic diet moderately reduced cathepsin S levels in normal-weight and overweight men and women. This effect may be partially mediated by diet-induced weight loss and possibly by reduced LDL-C concentrations.

Meanings of overweight In societal discourses overweight is defined as a growing individual and a social problem leading to sickness and disability, mental distress, increased use of health care and reduced economic productivity. A strong normative pressure is directed at the overweight but relatively few succeed in reducing their weight. Therefore, the overweight need to manage a double stigma; the overweight body per se and their inability to conform to norms about bodyweight. This article investigates how individuals present their overweight to their social environment. Empirical data was collected as part of an evaluation study of a keep-fit project directed at home-care staff. Qualitative interviews were conducted with 49 participants and 30 of them had either tried or were trying to reduce their weight. The analysis shows that the informants presented a divided self consisting of a biological body, with its own drives, and a mind that is aware of the body and its social meanings. They portrayed their lives as a battle between these two sides. Their presentations of the divided self can be analysed as a defence of their social selves. The overweight can account for the kilos by blaming the biological drives, which leaves the core of themselves – their minds – unblemished. They can express an intention to loose weight and thereby conform to norms about bodyweight. When they fail to loose weight, the responsibility can be attributed to the unruly body.

Bakgrund: Övervikt och fetma orsakar idag fler dödsfall än undervikt. Det är ett folkhälsoproblem som ökar över hela världen. Övervikt och fetma leder till såväl fysiska som psykiska problem och besvär för den drabbade. Forskning har visat att patienter med övervikt eller fetma upplever mest stigmatisering i vuxen ålder. Syfte: Syftet med denna litteraturöversikt är att belysa bemötandet av patienter med övervikts- och fetmaproblematik ur patientens och vårdpersonalens perspektiv. Metoder: En litteraturöversikt. Resultat: Det framkom att patienter med högre BMI upplevde negativt bemötande från vårdpersonal, att de inte blev hörda. Patienterna sökte inte gärna vård. Det framkommer att vårdpersonalen hade en negativ attityd till patienter med övervikt eller fetma och ville helst inte vårda dessa. Slutsats: Patienter med övervikt eller fetma är en utsatt patientgrupp i såväl samhälle som inom vården. Patienterna upplever att de inte blir hörda och inte blir tagna på allvar. Vårdpersonal är enig om att vården måste hjälpa dessa patienter, trots det uppger en stor del av vårdpersonal att de inte vill vårda patienter med övervikt eller fetma relaterat till tidsbrist.

Syfte: Syftet med studien är att beskriva distriktssköterskans erfarenhet av hälsosamtal avseende levnadsvanor med patienter som lever med övervikt eller fetma. Metod: En empirisk studie med kvalitativ ansats utfördes via enkätfrågor som var beskrivande med öppna svarsalternativ. I studien deltog fem distriktssköterskor som arbetade på vårdcentral i Dalarna eller på Gotland. Genom fenomenografisk design analyserades data. Resultat: Resultatet läggs fram genom två beskrivningskategorier; Evidensbaserade metoder som innehöll uppfattningsgrupperna; Utredning och behandling samt Bejaka patientens resurser. Beskrivningskategorin Omgivnings faktorer, hade uppfattningsgrupperna; Frekvensen av hälsosamtal samt Pedagogiskt förhållningssätt. Användning av evidensbaserade verktyg såsom midjemått och midja/höftkvot var låg bland distriktssköterskorna, men body mass index (BMI) samt motiverande samtal (MI) användes flitigt. Patienter söker ofta för andra besvär (högt blodtryck, ledbesvär) som kan återkopplas till kroppsvikten. Distriktssköterskorna erfarenhet var att det är svårt att komma tillrätta med viktproblem där motivation till viktnedgång var stark i början hos patienten men att den avtar. Dessa svårigheter kan bero på depression, skuld och skam hos patienterna. Slutsats: För att patienter med övervikt och fetma ska få den ultimata behandlingen krävs mer tid och resurser från hälso- och sjukvården då det kan vara en lång process att gå ner i vikt. Motivationen har en avgörande roll samt användning av evidensbaserade verktyg.

BACKGROUND: Increased circulating cathepsin S levels have been linked to increased risk of cardiometabolic diseases and cancer. However, whether cathepsin S is a modifiable risk factor is unclear. We aimed to investigate the effects of a prudent diet on plasma cathepsin S levels in healthy individuals. FINDINGS: Explorative analyses of a randomized study were performed in 88 normal to slightly overweight and hyperlipidemic men and women (aged 25 to 65) that were randomly assigned to ad libitum prudent diet, i.e. healthy Nordic diet (ND) or a control group (habitual Western diet) for 6 weeks. Whereas all foods in the ND were provided, the control group was advised to consume their habitual diet throughout the study. The ND was in line with dietary recommendations, e.g. low in saturated fats, sugars and salt, but high in plant-based foods rich in fibre and unsaturated fats.The ND significantly decreased cathepsin S levels (from 20.1 (+/-4.0 SD) to 19.7 μg/L (+/-4.3 SD)) compared with control group (from 18.2 (+/-2.9 SD) to 19.1 μg/L (+/-3.8 SD)). This difference remained after adjusting for sex and change in insulin sensitivity (P = 0.03), and near significant after adjusting for baseline cathepsin S levels (P = 0.06), but not for change in weight or LDL-C. Changes in cathepsin S levels were directly correlated with change in LDL-C. CONCLUSIONS: Compared with a habitual control diet, a provided ad libitum healthy Nordic diet decreased cathepsin S levels in healthy individuals, possibly mediated by weight loss or lowered LDL-C. These differences between groups in cathepsin S were however not robust and therefore need further investigation.
