Psychometric properties of the modified RESIDE physical activity questionnaire among low-income overweight women

Objectives This study explored the criterion-related validity and test-retest reliability of the modified RESIDential Environment physical activity questionnaire and whether the instrument's validity varied by body mass index, education, race/ethnicity, or employment status. Design Validation study using baseline data collected for randomized trial of a weight loss intervention. Methods Participants recruited from health departments wore an ActiGraph accelerometer and self-reported non-occupational walking, moderate and vigorous physical activity on the modified RESIDential Environment questionnaire. We assessed validity (n = 152) using Spearman correlation coefficients, and reliability (n = 57) using intraclass correlation coefficients. Results When compared to steps, moderate physical activity, and bouts of moderate/vigorous physical activity measured by accelerometer, these questionnaire measures showed fair evidence for validity: recreational walking (Spearman correlation coefficients 0.23–0.36), total walking (Spearman correlation coefficients 0.24–0.37), and total moderate physical activity (Spearman correlation coefficients 0.18–0.36). Correlations for self-reported walking and moderate physical activity were higher among unemployed participants and women with lower body mass indices. Generally no other variability in the validity of the instrument was found. Evidence for reliability of RESIDential Environment measures of recreational walking, total walking, and total moderate physical activity was substantial (intraclass correlation coefficients 0.56–0.68). Conclusions Evidence for questionnaire validity and reliability varied by activity domain and was strongest for walking measures. The questionnaire may capture physical activity less accurately among women with higher body mass indices and employed participants. Capturing occupational activity, specifically walking at work, may improve questionnaire validity.

Effectiveness of three different walking prescription durations on total physical activity in normal- and overweight women.

OBJECTIVE: While there is a dose-response relationship between physical activity (PA) and health benefit, little is known about the effectiveness of different PA prescriptions on total daily PA. AIM: To test, under real-life conditions and using an objective, non-invasive measurement technique (accelerometry), the effect of prescribing additional physical activity (walking only) of different durations (30, 60 and 90 min/day) on compliance (to the activity prescribed) and compensation (to total daily PA). Participants in each group were prescribed 5 sessions of walking per week over 4 weeks. METHODS: 55 normal-weight and overweight women (mean BMI 25 ± 5 kg/m(2), height 165 ± 1 cm, weight 68 ± 2 kg and mean age 27 ± 1 years) were randomly assigned to 3 prescription groups: 30, 60 or 90 min/day PA. RESULTS: Walking duration resulted in an almost linear increase in the number of steps per day during the prescription period from an average of about 10,000 steps per day for the 30-min prescription to about 14,000 for the 90-min prescription. Compliance was excellent for the 30-min prescription but decreased significantly with 60-min and 90-min prescriptions. In parallel, degree of compensation subsequent to exercise increased progressively as length of prescription increased. CONCLUSION: A 30-min prescription of extra walking 5 times per week was well tolerated. However, in order to increase total PA further, much more than 60 min of walking may need to be prescribed in the majority of individuals. While total exercise 'volume' increased with prescriptions longer than 30 min, compliance to the prescription decreased and greater compensation was evident. © 2014 S. Karger GmbH, Freiburg.

Weight-related risk perception among healthy and overweight pregnant women: A cross-sectional study

Objective The objective of this study was to evaluate weight-related risk perception in early pregnancy and to compare this perception between women commencing pregnancy healthy weight and overweight. Study design Pregnant women (n=664) aged 29±5 (mean±s.d.) years were recruited from a metropolitan teaching hospital in Australia. A self-administered questionnaire was completed at around 16 weeks of gestation. Height measured at baseline and self-reported pre-pregnancy weight were used to calculate body mass index. Cross-sectional analysis was conducted. Differences between groups were assessed using chi-squared tests for categorical variables and t-tests or Mann–Whitney U tests for continuous variables depending on distribution. Result Excess gestational weight gain (GWG) during pregnancy was more important in leading to health problems for women or their child compared with pre-pregnancy weight. Personal risk perception for complications was low for all women, although overweight women had slightly higher scores than healthy-weight women (2.4±1.0 vs 2.9±1.0; P<0.001). All women perceived their risk for complications to be below that of an average pregnant woman. Conclusion Women should be informed of the risk associated with their pre-pregnancy weight (in the case of maternal overweight) and excess GWG. If efforts to raise risk awareness are to result in preventative action, this information needs to be accompanied by advice and appropriate support on how to reduce risk.

Orange juice improved lipid profile and blood lactate of overweight middle-aged women subjected to aerobic training

Objective This study investigated how consumption of orange juice associated with aerobic training affected serum lipids and physical characteristics of overweight middle-aged womenMethods The experimental group consisted of 13 women who consumed 500 mL/d of orange juice and did 1 h aerobic training 3 times a week for 3 months The control group consisted of another 13 women who did the same aerobic training program but did not consume orange juiceResults At the end of the experiment the control group lost an average of 15% of fat mass (P < 0 05) and 25% of weight (P < 0 05) whereas the experimental group lost 11% of fat mass and 1 2% of weight (P < 0 05) Consumption of orange juice by the experimental group was associated with Increased dietary intake of vitamin C and folate by 126% and 61% respectively Serum LDL-C decreased 15% (P < 0 05) and HDL-C increased 18% (P < 0 05) in the experimental group but no significant change was observed in the control group Both groups improved the anaerobic threshold by 20% (P < 0 05) but blood lactate concentration decreased 27% in the experimental group compared to the 17% control group suggesting that experimental group has less muscle fatigue and better response to trainingConclusions The consumption of 500 mL/d of orange juice associated with aerobic training in overweight women decreased cardiovascular disease risk by reducing LDL-C levels and increasing HDL-C levels This association also decreased blood lactate concentration and increased anaerobic threshold showing some improvement in the physical performance (C) 2010 Elsevier B.V.

A prospective study of pregnancy weight gain in Australian women

Background: While weight gain during pregnancy is regarded as important, there has not been a prospective study of measured weight gain in pregnancy in Australia. This study aimed to prospectively evaluate pregnancy-related weight gain against the Institute of Medicine (IOM) recommendations in women receiving antenatal care in a setting where ongoing weight monitoring is not part of routine clinical practice, to describe women's knowledge of weight gain recommendations and to describe the health professional advice received relating to gestational weight gain (GWG). Methods: Pregnant women were recruited ≤20 weeks of gestation (n = 664) from a tertiary obstetric hospital between August 2010 to July 2011 for this prospective observational study. Outcome measures were weight gain from pre-pregnancy to 36 weeks of gestation, weight gain knowledge and health professional advice received. Results: Thirty-six percent of women gained weight according to guidelines. Twenty-six percent gained inadequate weight, and 38% gained excess weight. Fifty-six percent of overweight women gained weight in excess of the IOM guidelines compared with 30% of those who started with a healthy weight (P < 0.001). At 16 weeks, 47% of participants were unsure of the weight gain recommendations for them. Sixty-two percent of women reported that the health professionals caring for them during this pregnancy ‘never’ or ‘rarely’ offered advice about how much weight to gain. Conclusions: The prevalence of inappropriate gestational weight gain in this study was high. The majority of women do not know their recommended weight gain. The advice women received from health professionals relating to healthy weight gain in pregnancy could be improved.

Are we missing opportunities? Understanding health behaviours associated with overweight in pregnancy

While maternal obesity, excess pregnancy weight gain and lifestyle behaviours are associated with future overweight for both mothers and babies, there is limited research on how best to intervene. An evidence base that identifies behavioural influences is crucial to the development of effective interventions. This thesis aims to gain an understanding of maternal behavioural outcomes of healthy eating, physical activity and gestational weight gain (GWG), the psychosocial influences on these and to examine differences according to pre-pregnancy weight status. The New Beginnings Healthy Mothers and Babies Study was a prospective observational study using the PRECEDE-PROCEED model of health promotion planning as a framework. A consecutive sample of 715 women was recruited. Height and weight were measured and women completed questionnaires at approximately 16 and 36 weeks gestation. This thesis presents three chapters of original research across four study domains. While healthy eating was widely regarded as important during pregnancy and had become more so, there was more variability in attitudes towards physical activity. Ninety-two percent of participants achieved the maximum knowledge score relating to the influence of nutrition on pregnancy. However, 8% and 36% respectively knew how many serves of fruit and vegetables should be consumed daily. Six percent of participants met the recommendations for fruit consumption, 4% achieved the recommended vegetable intake and 44% achieved sufficient physical activity. There were few differences between healthy and overweight women for measures of physical activity and healthy eating. Many predisposing, reinforcing and enabling factors with a positive influence on health behaviours were lower in women commencing pregnancy overweight and those factors with a negative influence on health behaviours were higher when compared to healthy weight women. Some of these antecedents to health behaviours that were different according to prepregnancy weight status were associated with diet quality and physical activity. While self efficacy was consistently associated with diet quality and physical activity for both weight groups, other associations between specific predisposing, reinforcing and enabling factors differed with behaviour and weight status group. These results highlight the complexity of supporting behaviour change in a one-size-fits-all approach. Sixty-four percent of participants gained weight outside of recommendations. Compared to healthy weight women, those women who were already overweight at the beginning of pregnancy were more likely to gain too much weight (30% vs 56%, p<0.001). Only 35% of participants reported their correct recommended weight gain. Excess GWG was associated with few predisposing factors, however, these were not consistent between prepregnancy weight status groups. Less than 50% of women reported sometimes/usually/always receiving advice from health professionals relating to healthy eating, physical activity or GWG. These results indicate that there are opportunities to improve the advice and support provided by health care professionals in the antenatal period. Evidence from this PhD research suggests that there is a need for effective prevention and management of excess weight in pregnancy. Effective management of this problem is likely to require a multidisciplinary approach with multi-level strategies. Importantly, the strategies may need to be tailored according to pre-pregnancy weight status. Collectively, the evidence derived from this thesis suggests that opportunities to support healthy lifestyles and prevent future overweight are being missed during pregnancy.

Health correlates of overweight and obesity in adults aged 50 years and over: results from the Survey of Health, Ageing and Retirement in Europe (SHARE)

QUESTIONS UNDER STUDY: To examine the association between overweight/obesity and several self-reported chronic diseases, symptoms and disability measures. METHODS: Data from eleven European countries participating in the Survey of Health, Ageing and Retirement in Europe were used. 18,584 non-institutionalised individuals aged 50 years and over with BMI > or = 18.5 (kg/m2) were included. BMI was categorized into normal weight (BMI 18.5-24.9), overweight (BMI 25.0-29.9) and obesity (BMI > or = 30). Dependent variables were 13 diagnosed chronic conditions, 11 health complaints, subjective health and physical disability measures. For both genders, multiple logistic regressions were performed adjusting for age, socioeconomic status and behaviour risks. RESULTS: The odds ratios for high blood pressure, high cholesterol, diabetes, arthritis, joint pain and swollen legs were significantly increased for overweight and obese adults. Compared to normal-weight individuals, the odds ratio (OR) for reporting > or = 2 chronic diseases was 2.4 (95% CI 1.9-2.9) for obese men and 2.7 (95% CI 2.2-3.1) for obese women. Overweight and obese women were more likely to report health symptoms. Obesity in men (OR 0.5, 95% CI 0.4-0.6), and overweight (OR 0.5, 95% CI 0.4-0.6) and obesity (OR 0.4, 95% CI 0.3-0.5) in women, were associated with poorer subjective health (i.e. a decreased risk of reporting excellent, very good or good subjective health). Disability outcomes were those showing the greatest differences in strength of association across BMI categories, and between genders. For example, the OR for any difficulty in walking 100 metres was non-significant at 0.8 for overweight men, at 1.9 (95% CI 1.3-2.7) for obese men, at 1.4 (95% CI 1.1-1.8) for overweight women, and at 3.5 (95% CI 2.6-4.7) for obese women. CONCLUSIONS: These results highlight the impact of increased BMI on morbidity and disability. Healthcare stakeholders of the participating countries should be aware of the substantial burden that obesity places on the general health and autonomy of adults aged over 50.

Influence of body composition on bone mass in postmenopausal osteoporotic women

We aimed at evaluating the relationship of lean and fat mass to bone mass in osteoporotic postmenopausal women. We invited 65 women who were being treated at the Sao Paulo Hospital osteoporosis outpatients` clinic to participate. Body composition and bone mineral density (BMD) measurements were performed using Dual-energy X-ray absorptiometry methodology (DXA). The mean age and weight were 69.7 +/- 6.4 years and 56.3 +/- 7.6 kg, respectively. Accordingly to the body mass index (BMI), 52.8% were of normal weight and 47.1% of the patients were overweight. Overweight women had significantly higher bone mass. Similarly, skeletal muscle index (SMI) showed a positive effect on BMD measurements and women with sarcopenia had significantly lower BMD measurements in total femur and femoral neck. In multiple regression analysis only lean mass and age, after adjustments to fat mass and BMI, were able to predict total body bone mineral content (BMC) (R(2) = 28%). Also lean mass adjusted to age and BMI were able to predict femoral neck BMD (R(2) = 14%). On the other hand, none of the components of the body composition (lean mass or fat mass) contributed significantly to explaining total femur BMD and neither body composition measurements were associated with spine BMD. These findings suggest that lean mass has a relevant role in BMC and BMD measurements. In addition, lower BMI and lean mass loss (sarcopenia) is associated to lower BMC and BMD of femoral neck and total femur and possible higher risk of osteoporotic fracture.

Metformin versus lifestyle changes in treating women with polycystic ovary syndrome

Objective: To compare the efficacy of metformin with that of lifestyle changes in patients with polycystic ovary syndrome (PCOS). Design: Prospective, randomized clinical trial of 40 women with PCOS to analyze the effects of metformin and lifestyle intervention treatments on menstrual pattern and hormone and metabolic profile. The duration of treatment was 6 months. Statistical analysis was done using Student's t-test. Results: Fifteen women in the metformin group and 12 in the lifestyle changes group completed the study. The menstrual pattern improved by similar to 67% in both groups. There was a significant decrease in waist circumference in the lifestyle changes group (101.8 +/- 3.9 and 95.1 +/- 3.6, at baseline and at 6 months of treatment, respectively; p<0.001) and in body mass index (BMI) in both groups. The predictor of menstrual pattern improvement was BMI. Conclusions: Both metformin and lifestyle changes may increase the number of menstrual cycles in PCOS. This effect was related to a decrease in BMI.

Contraceptive use in women by body mass index categories

The prevalence of obesity has increased sharply in the United States since the mid 1970's. Obese women who become pregnant are at increased risk of pregnancy complications for both mother and fetus. This study assessed whether women in higher body mass index (BMI) categories engage in the preventive behaviors of contraception more frequently than normal weight women. It also evaluated the type of contraception used by both obese and normal weight women. The study used cross-sectional data from 7 states participating in the Family Planning Module of the 2006 Behavioral Risk Factor Surveillance System (BRFSS). The Behavioral Risk Factor Surveillance System survey is an annual random digit dialed telephone survey of the non-institutionalized civilian population aged 18 years and older. The Family Planning Module was administered by Arizona, Kentucky, Minnesota, Missouri, Montana, Oregon, and Wisconsin. Of the 4,757 women who participated in the Family Planning Module, 2,244 (53.2%) were normal weight, 1,202 (25.6%) were overweight, and 1,072 (21.2%) were obese. The majority of these women 4,115 (86.2%) reported using some type of contraception to prevent pregnancy. Six hundred forty two women (13.8%) stated they did not use any type of contraception to prevent pregnancy. Within body mass index categories, 14% of normal weight women, 13% of overweight women, and 13.4% of obese women did not use any type of contraception. Neither the bivariate analysis nor the logistic regressions found body mass index categories to be statistically associated with contraceptive use. The relationship between body mass index categories and contraceptive method was found to be statistically significant. The predictive probability graph found that women at all levels of BMI have a lower probability of using barrier contraception methods as compared to procedural and hormonal methods. Hormonal contraception methods have the highest probability of use for women with a BMI of 15 to 25. In contrast, the probability of using procedural contraception methods is relatively flat and less than hormonal methods for BMI between 15 and 25. However, the probability of using procedural contraception increases dramatically with a BMI greater than 25. At a BMI greater than 42, women have a greater than 50% probability of using procedural contraception. Although a relationship between body mass index and contraception use was not found, contraception method was found to be associated with body mass index. The reasons why normal weight women prefer hormonal contraception while overweight/obese women are more likely to use procedural methods needs to be explored. By understanding the relationship between obesity and contraception, we can hopefully decrease unintended pregnancies and overall improve pregnancy related health outcomes. To determine if relationships between contraception use/type and body mass index exist, further research needs to be conducted on a national level. ^

An observational study of nutrition and physical activity behaviours, knowledge, and advice in pregnancy

Maternal obesity, excess weight gain and lifestyle behaviours during pregnancy have been associated with future overweight and other adverse health outcomes for mothers and babies. This study compared the nutrition and physical activity behaviours of Australian healthy (BMI ≤ 25 k/m2) and overweight (BMI ≥ 25 kg/m2) pregnant women and described their knowledge and receipt of health professional advice early in pregnancy. Methods Pregnant women (n=58) aged 29±5 (mean±s.d.) years were recruited at 16±2 weeks gestation from an Australian metropolitan hospital. Height and weight were measured using standard procedures and women completed a self administered semi-quantitative survey. Results Healthy and overweight women had very similar levels of knowledge, behaviour and levels of advice provided except where specifically mentioned. Only 8% and 36% of participants knew the correct recommended daily number of fruit and vegetable serves respectively. Four percent of participants ate the recommended 5 serves/day of vegetables. Overweight women were less likely than healthy weight women to achieve the recommended fruit intake (4% vs. 8%, p=0.05), and more likely to consume soft drinks or cordial (55% vs 43%, p=0.005) and take away foods (37% vs. 25%, p=0.002) once a week or more. Less than half of all women achieved sufficient physical activity. Despite 80% of women saying they would have liked education about nutrition, physical activity and weight gain, particularly at the beginning of pregnancy, less than 50% were given appropriate advice regarding healthy eating and physical activity. Conclusion Healthy pregnancy behaviour recommendations were not being met, with overweight women less likely to meet some of the recommendations. Knowledge of dietary recommendations was poor and health care professional advice was limited. There are opportunities to improve the health care practices and education pregnant women received to improve knowledge and behaviours. Pregnant women appear to want this.

Efeitos do estradiol sobre a função endotelial, sensibilidade insulínica e viscosidade sanguínea em mulheres na pós-menopausa com excesso de peso

A ação que o estrogênio desempenha sobre o endotélio depende da integridade deste e consequentemente das características clínicas de cada indivíduo. O uso da terapia hormonal da menopausa (THM) em mulheres com baixo risco cardiovascular geralmente resulta em efeitos benéficos, desde que iniciado em um período próximo da menopausa. Em contrapartida, o seu uso em mulheres com alto risco cardiovascular, como diabéticas ou portadoras de lesões ateroscleróticas já estabelecidas, e ainda naquelas com início da THM em um período superior a dez anos da menopausa geralmente resulta em efeitos maléficos. Nosso objetivo é avaliar os efeitos do estrogênio sobre a função endotelial em mulheres com sobrepeso ou obesidade, ou seja, indivíduos com risco cardiovascular intermediário. Para isso, 44 mulheres na pós-menopausa com idade entre 47 a 55 anos e índice de massa corporal (IMC) de 27,5 a 34,9kg/m, foram randomizadas nos grupos placebo (P) e estrogênio transdérmico (ET). A intervenção consistiu no uso transdérmico de estradiol, 1mg por dia, por um período de três meses. As participantes realizaram avaliação da reatividade endotelial em repouso e após isquemia [pletismografia por oclusão venosa (POV), com medidas do fluxo sanguíneo do antebraço (FSA) e videocapilaroscopia dinâmica do leito periungueal (VCLP), com medidas da velocidade de deslocamento das hemácias (VDH)], dosagens de moléculas de adesão [E-selectina, molécula de adesão intercelular (ICAM-1) e molécula de adesão vascular (VCAM-1)], aferição da sensibilidade insulínica [através do homeostatic model assessment of insulin resistance (HOMA-IR) e área sob a curva (AUC) da insulina durante o teste oral de tolerância à glicose (TOTG)] e mensurações das viscosidades sanguínea e plasmática. As participantes apresentaram idade de 51,77 2,3 anos, IMC de 31,52 2,54 kg/m e tempo de menopausa de 3 [2-5] anos. O grupo P não apresentou nenhuma mudança significativa em qualquer variável. Após a intervenção, o grupo ET comparado ao basal apresentou menor tempo para atingir a VDH máxima durante a hiperemia reativa pós-oclusiva (HRPO) após 1 min de isquemia (4,0 [3,25-5,0] vs. 5,0 [4,0-6,0] s, P<0.05) e maior VDH tanto em repouso (0,316 [0,309-0,326] vs. 0,303 [0,285-0,310] mm/s; P<0,001) quanto na HRPO (0,374 [0,353-0,376] vs. 0,341 [0,334-0,373] mm/s; P<0,001), assim como observamos maior FSA em repouso (2,46 [1,81-3,28] vs. 1,89 [1,46-2,44] ml/min.100ml tecido-1; P<0,01) e durante a HRPO após 3 min de isquemia (6,39 [5,37-9,39] vs. 5,23 [4,62-7,47] ml/min.100ml tecido-1; P<0,001). O grupo ET também apresentou diminuição nos níveis solúveis de E-Selectina (68,95 [50,18-102,8] vs. 58,4 [44,53-94,03] ng/ml; P<0,05), de ICAM-1 (188 [145-212] vs. 175 [130-200] ng/ml; P<0,01), do HOMAIR (3,35 1,67 vs. 2,85 1,60; P<0,05) e da AUC da insulina durante o TOTG (152 [117-186] vs. 115 [85-178]; P<0,01), além de diminuição das viscosidades sanguínea com hematócrito nativo (3,72 0,21 vs. 3,57 0,12 mPa.s; P<0,01) e plasmática (1,49 0,10 vs. 1,45 0,08 mPa.s; P<0,05), comparado ao seu basal. Em conclusão o uso de estradiol transdérmico em mulheres com excesso de peso e menopausa recente, promove melhora da função endotelial, além de oferecer proteção a outros fatores de risco cardiovascular.

Étude-pilote portant sur une intervention de groupe auprès de femmes souffrant d’hyperphagie boulimique et l’évaluation de ses effets potentiels

Cette étude porte sur une intervention de groupe basée sur la thérapie cognitivo-comportementale pour l’hyperphagie boulimique (HB), dont les effets potentiels sur la qualité de vie reliée au poids, la fréquence et la sévérité des crises de boulimie, les symptômes dépressifs, l’image corporelle et le poids corporel ont été mesurés, et le degré d’acceptation par les participantes a été documenté. Ainsi, 11 femmes avec un surplus de poids et répondant aux critères diagnostiques de l’HB ont été recrutées du printemps 2012 à l’hiver 2013, dans la région de Montréal. Le programme comportant huit séances hebdomadaires était dispensé par une nutritionniste et une psychothérapeute. La qualité de vie reliée au poids (Impact of Weight on Quality of Life), la fréquence des crises de boulimie (rappel des sept derniers jours), la sévérité des crises de boulimie (Binge Eating Scale), les symptômes dépressifs (Inventaire de Beck pour la dépression), l’insatisfaction corporelle (Body Shape Questionnaire) et le poids corporel ont été mesurés avant et à la fin de l’intervention. Puis, un questionnaire pour mesurer l’acceptation par les participantes était soumis au terme du programme. Le taux de participation aux séances était aussi colligé. Les résultats montrent que notre programme a permis une amélioration significative du score global de la qualité de vie reliée au poids de 8,4 ± 13,3, ainsi qu’en termes d’estime de soi et de travail. Aussi, une diminution significative de la fréquence des crises de boulimie de 2,1 ± 2,1 jours, de la sévérité des crises de boulimie dont le score a diminué de 10,9 ± 7,7, des symptômes dépressifs dont le score a diminué de 8,3 ± 5,7 et de l’insatisfaction corporelle dont le score a diminué de 32,8 ± 17,1, ont été observées. Toutefois, il n’y a pas eu de perte de poids au terme de l’intervention. Puis, le programme a été bien accepté par les participantes tel que démontré par le taux de participation aux séances de 93,8 % et la satisfaction mesurée par l’appréciation des divers éléments du programme de 4,6 sur 5 et la pertinence de ceux-ci de 4,8 sur 5. Ces données suggèrent que l’intervention de groupe semble être prometteuse pour améliorer les symptômes et conséquences de l’HB, à l’exception du poids.

Prevalencia de obesidad y factores de riesgo cardiovascular en estudiantes de ciencias de la salud - universidad del Quindío - 2013

ANTECEDENTES: En Colombia, reportes del año 2010 de la Encuesta Nacional de la Situación en Nutrición ENSIN 2010(2), muestran uno de cada dos colombianos, presentan un índice de masa corporal mayor al esperado (3) METODO: El presente estudio de corte transversal, determino la prevalencia de obesidad y otros factores de riesgo cardiovascular en una población de estudiantes de Ciencias de la Salud de una Universidad regional en el primer periodo académico del año 2013. El tamaño de muestra fue n=113 sujetos que corresponden 60,5% a la carrera de medicina y 39,95% a enfermería. Con el fin de conocer su comportamiento con respecto a hábitos y estilos de vida específicos como el consumo de alcohol, el consumo de tabaco y el sedentarismo, así como su asociación a eventos inflamatorios relacionados con la fisiopatología de los procesos de salud asociados al peso, por medio de instrumentos de medición clínica, antropométrica y sérica, determino un modelo estadístico propicio para entender el comportamiento de la obesidad y la enfermedad Cardiovascular RESULTADOS: La prevalencia estimada de sobrepeso y obesidad por Índice de Masa Corporal (IMC), fue del 27,7% (IC 95%: 19.9%,37.2%); por el perímetro abdominal (OBPABD) se encontró una prevalencia estimada del 27,4% (IC 95%: 19,9% – 36,4%), y la prevalencia con el Índice Cintura Cadera (OBICC) fue de 3,5% (IC 95%:1,3% – 9,3%). CONCLUSIONES: La presencia de hábitos no saludables y la presencia de sobrepeso y obesidad se considera que es necesario en primera instancia una valoración general de estado nutricional de los universitarios de las diferentes facultados y plantear estrategias preventivas ya que la literatura documenta los efectos de los hábitos no saludables sino además documenta los efectos de la prevención de la misma ya que en si se ha encontrado asociación para enfermedades cardiovasculares. Se propone que para obtener mayor información del comportamiento de los factores de riesgo cardiovasculares se deberían realizar estudios retrospectivos en el que intervengan las demás carreras de la universidad y poder evaluar la totalidad de población universitaria
