Objective: To assess the effectiveness of nutritional intervention in overweight women undergoing Primary Health Care. Methods: An intervention study was conducted with overweight adult and elderly women aged 20 years or older (body mass index ≥25.0 kg/m² and ≥27.0 kg/m², respectively) who were subjected to 12 months of individual nutritional monitoring. The effectiveness of the intervention was assessed by dietary, health, and anthropometric indicators. Results: Most of the 71 individuals were adults with a low income and poor level of education. After the intervention, there was an increase in number of meals and in the frequency of breakfasting. Moreover, there were more fruits and vegetables consumed, in addition to a decrease in household availability of salt, sugar, oil, and fried foods consumption. An improvement in health and weight self-perception was observed, as well as a decrease in body mass and abdominal adiposity, in particular among those participating in several consultations (n >9). Conclusion: The proposed nutritional intervention was effective and viable for improving the care of overweight individuals and those suffering from destabilized comorbidities...

The aim of this study was to investigate the prevalence of body image perception and its association with anthropometric indicators (body mass index, waist circumference, waist-height ratio, and conicity index) in women undergoing cervical cancer screening at an institution in Florianópolis, Santa Catarina. The study included 736 women (≥ 18 years). Anthropometric variables (weight, height, waist circumference) were collected for the determination of body mass index, waist-height ratio, and conicity index. Body image perception was evaluated using a nine-body silhouette scale. The prevalence of body image dissatisfaction was 73% (dissatisfaction due to excess weight = 67.4%; dissatisfaction due to thinness = 5.6%). Overweight women (PR=1.34; 95%CI=1.23-2.49, p<0.001) and women with an inadequate conicity index (PR=1.12; 95%CI =1.02-1.24, p=0.016) presented a higher prevalence of body image dissatisfaction. The prevalence of body image dissatisfaction is high and the proportion of inadequate anthropometric indicators requires attention. Moreover, body dissatisfaction was more prevalent among overweight women and women with an inadequate conicity index. These results indicate the need for interventions and for the implementation of programs designed to control body weight and to reduce cardiovascular risk factors and body image dissatisfaction in women attending primary health care centers...

Studies, in countries with high seafood consumption, suggested its benefit on fetal growth and child development. The objective of our study was to determine the association between seafood consumption in French pregnant women and fetal growth. Pregnant women included in the EDEN mother-child cohort study completed two food frequency questionnaires on their usual diet in the year before and during the last three months of pregnancy (n=1805). Fetal circumferences were measured by ultrasound, and anthropometry at birth. Variables were compared across tertiles of the mother’s seafood consumption by multiple linear regressions adjusted for confounding variables. Analyses were stratified according to maternal overweight because of interaction (p<0.01). As results, there was no association between seafood intake and fetal growth in the whole sample of women. For overweight women (n=464), a higher consumption before pregnancy was associated with higher fetal biparietal and abdominal circumferences and anthropometric measures. From the lowest to the highest tertiles, mean birthweight was 167g higher (p=0.002). No significant association was found with consumption at the end of pregnancy. In conclusion, high seafood consumption before pregnancy is positively associated with fetal growth in overweight women. Follow-up of the infants may help determine potential beneficial consequences for the child’s health and development.

Numerous studies have reported that Black women are more satisfied with their bodies than White women. The buffering hypothesis suggests that aspects of Black culture protect Black women against media ideals that promote a slender female body type; therefore, Black women are expected to exhibit higher body esteem than White women. To test this hypothesis, the current study aimed to assess the influence of race on weight perception, perceived attractiveness, and the interrelations between body mass index (BMI) and perceived attractiveness among overweight and obese women. Participants were 1,694 respondents of Wave IV of the National Longitudinal Study on Adolescent Health (M = 28.89 years). Black (n = 531) or White (n = 1163) obese or overweight women were included in the current study. As expected, Black women reported lower perceived weight and higher attractiveness than White women, despite higher body mass for Black women. Furthermore, race moderated the relationship between BMI and perceived attractiveness; for White women, a negative relationship existed between BMI and attractiveness, whereas for Black women, BMI and attractiveness were not related. The study findings provide further support for the buffering hypothesis, indicating that despite higher body mass...

Despite extensive research, the effects of α-tocopherol supplementation remain controversial. Few studies have been focused on obese and overweight people. We examined the effects of α-tocopherol (AT) on the oxidative status and metabolic profile in overweight women. Sixteen overweight women between the ages of 40–60 years old, received AT, 800 IU/day during 12 weeks, followed by a 6-week washout period. Blood samples were taken at the beginning and then every 6 weeks until the end of the study. AT, retinol, malondialdehyde (MDA), total antioxidant status (TAS), selenium-dependent glutathione peroxidase (GPx) and CuZn-superoxide dismutase (SOD) were quantified to evaluate the oxidative stress. The metabolic profile was estimated by measuring glycated hemoglobin (HbA1c) in erythrocytes and glucose, phosphate, magnesium, lipid and lipoprotein concentrations in serum. Under AT administration HbA1c, serum-MDA levels and erythrocyte GPx activity were markedly reduced. TAS, AT and Mg2+ concentrations in serum and SOD activity in erythrocytes were higher after AT treatment. Body weight; glucose, lipid and retinol concentrations, or blood cells count were unchanged. Lipid peroxidation was considerably reduced in AT treated women and also improved serum antioxidant status was observed...

Obesity and gestational diabetes mellitus (GDM) are increasing worldwide and may compromise female sexual function. We hypothesize that among GDM patients in the third trimester of pregnancy, those with excess body fat would have worse female sexual function scores than normal weight women. Our aim was to assess the sexual function of overweight compared to normal weight women with GDM. This was a cross-sectional survey involving 143 Brazilian women with GDM in the third trimester of pregnancy: 76 were overweight (pre-pregnancy body mass index-BMI≥25.0 Kg/m2) and 67 were normal weight (BMI 18.5–24.9 Kg/m2). Participants were recruited from March 2010 to April 2013 at the antenatal clinic of a single public tertiary teaching institution. The Female Sexual Function Index (FSFI) questionnaire was used to assess sexual function. Overall, 51.7% of the 143 participants were at risk for sexual dysfunction symptoms (FSFI scores ≤26); this rate was significantly higher among overweight compared to normal weight women (60.5% versus 41.8%, p = 0.038). Mean total FSFI scores were significantly lower in overweight compared to normal weight women (21.7±9.2 versus 24.9±8.0, p = 0.029). Compared to normal weight women, overweight participants had lower mean scores in desire (3.4±1.2 versus 4.0±1.4...

BACKGROUND: Polycystic ovary syndrome (PCOS) is a common condition associated with obesity and with reproductive and metabolic dysfunction. Abnormalities in appetite regulation in PCOS patients may contribute to difficulties in weight management. OBJECTIVE: We aimed to examine appetite, appetite hormones, and ad libitum food consumption before and after weight loss in overweight women with and without PCOS. DESIGN: Overweight age- and weight-matched women with (n = 14) and without (n = 14) PCOS undertook an 8-wk energy-restricted diet (5185.3 +/- 141.6 kJ/d). At baseline and study end, subjects consumed a test meal (936 kJ; 25% of energy from protein, 9% from fat, and 67% from carbohydrate). Subjective appetite and circulating glucose, insulin, ghrelin, cholecystokinin, and peptide YY were assessed at 0, 15, 30, 45, 60, 90, 120, and 180 min. A mixed buffet lunch was then offered to assess ad libitum food intake. RESULTS: Weight loss (4.2 +/- 3.9 kg) did not differ significantly between the 2 groups. Women with PCOS had significantly (P = 0.023) lower ghrelin concentrations before and after weight loss than did women without PCOS. The degree of postprandial ghrelin suppression was lower at weeks 0 (P = 0.048) and 8 (P = 0.069) in women with PCOS than in women without PCOS. There were no significant differences between the 2 groups in appetite responses...

BACKGROUND: Polycystic ovary syndrome (PCOS) is associated with reproductive and metabolic abnormalities. It is unknown whether overweight women with and without PCOS achieve similar benefits from weight loss for cardiovascular risk factors. METHOD: Overweight body mass index-matched women with (n = 15) and without (n = 17) PCOS (weight, 95.3 +/- 17.6 kg; body mass index, 35.6 +/- 5.3 kg/m(2), mean +/- sd) followed an 8-wk weight loss regime. RESULTS: All subjects had similar reductions in weight (3.9 +/- 3.6 kg, 3.8%, vs. 4.5 +/- 4.1 kg, 4.7%, respectively, for PCOS and non-PCOS), waist circumference, fat mass, triglycerides, free testosterone, and fasting and postprandial insulin. At baseline, C-reactive protein (CRP) between groups was not significantly different (5.5 +/- 3.1 mg/liter for PCOS vs. 4.9 +/- 3.0 mg/liter for non-PCOS). There was a significant interaction between PCOS status and CRP (P = 0.016) such that CRP decreased with weight loss for non-PCOS women (-1.2 +/- 1.8 mg/liter; P = 0.025) but not for PCOS women. For all women, the change in CRP correlated with the change in weight (r = 0.560; P = 0.003), fat mass (r = 0.477; P = 0.016), and postprandial insulin (r = 0.402; P = 0.046). Adiponectin, IL-6, and TNF-alpha were not significantly different between groups before or after weight loss. Only subjects with baseline CRP levels below the median (4.52 mg/liter) showed increases in adiponectin (0.98 +/- 1.3 microg/liter) (P = 0.015) and greater reductions in triglycerides (P = 0.001) with weight loss. CONCLUSION: A 4-5% weight loss improved lipid...

BACKGROUND: Polycystic ovary syndrome (PCOS) is associated with reproductive and metabolic abnormalities, specifically menstrual dysfunction and anovulation in conjunction with elevated pre-antral follicle number and arrested follicular maturation. Although anti-müllerian hormone (AMH), an inhibitor of follicle recruitment and maturation, is increased in women with PCOS, the usefulness of circulating AMH levels as a clinical predictor of menstrual response to weight loss in PCOS is not known. METHODS: Overweight women with PCOS (n = 26, age 32.9 +/- 5.8 yr, weight 98.9 +/- 20.8 kg, body mass index 36.1 +/- 7.0 kg/m(2), mean +/- sd) followed an 8-wk weight loss and 6-month weight maintenance program. RESULTS: Net reductions in weight (4.6 +/- 4.8 kg), waist circumference (6.0 +/- 5.3 cm), testosterone (0.3 +/- 0.6 nmol/liter), fasting insulin (3.7 +/- 7.6 mU/liter), and the homeostasis model assessment of insulin sensitivity (0.7 +/- 1.3) occurred for all subjects over the entire study duration. Of 26 subjects, 15 (57.7%) responded to the intervention with improvements in menstrual cyclicity (responders). Compared to nonresponders, responders had lower AMH levels at baseline (23.6 +/- 12.0 vs. 37.9 +/- 17.8 pmol/liter; P = 0.021). Only responders had reductions in fasting insulin (6.1 +/- 5.9 mU/liter; P = 0.001) and homeostasis model assessment (1.3 +/- 5.9; P = 0.002) with acute weight loss (wk 0-8). Baseline AMH was most strongly predicted by baseline ghrelin...

In the general population, one in five couples experiences difficulty in conceiving a child. The role of obesity on women’s fecundity has become a focus of attention in recent years. Successful treatment of infertility through Assisted Reproductive Technology (ART) is also compromised by the presence of obesity, which occurs in 30 % of women seeking treatment. A negative correlation exists between increased body mass index (BMI) and the number of collected oocytes and a lower birth rate after ART. Furthermore, a number of studies have established that weight loss improves natural conception rates in overweight women. Whether weight management can improve success rates in overweight / obese women undergoing in vitro fertilisation (IVF) has not been studied. The purpose of this project was to explore the role of short–term weight loss on potential pregnancy outcomes in overweight / obese women undergoing IVF programme. However, to establish this relationship, we proposed to carry out two studies to assess the following: (I) The feasibility of very low calorie diet (VLCD) during IVF treatment with respect to duration, level of restriction and tolerability of the diet during hormonal down regulation in women (Chapter 2). (II) How energy restriction may affect the quality of an early embryo in diet - induced obese mice with respect to various body weight and caloric intake (Chapter 3). In study (I)...

Context: In overweight women with polycystic ovary syndrome (PCOS), the benefits of the addition of exercise to an energy-restricted diet in further improving cardiometabolic risk factors and reproductive function has not been extensively studied. Objective: The objective was to evaluate the effects of aerobic and aerobic-resistance exercise when combined with an energy-restricted high protein diet (5000–6000 kJ/d) on metabolic risk factors and reproductive function in women with PCOS. Design and Setting: A 20-wk outpatient, randomized, parallel study was conducted in a metropolitan research clinic. Patients and Intervention: Ninety-four overweight and obese women with PCOS (age 29.3 ± 0.7 yr; body mass index 36.1 ± 0.5 kg/m2) were randomized to diet only (DO; n = 30), diet and aerobic exercise (DA; n = 31), or diet and combined aerobic-resistance exercise (DC; n = 33). Main Outcome Measures: Weight, body composition, cardiometabolic risk factors, hormonal status, menstrual cyclicity, and ovulatory function were assessed. Results: All interventions reduced weight (DO 8.9 ± 1.6%, DA 10.6 ± 1.7%, and DC 8.7 ± 1.7%; P < 0.001) with no difference between treatments (P = 0.7, time x treatment). Fat mass decreased more (3 kg) and fat-free mass decreased less (2 kg) in DA and DC compared with DO (P ≤ 0.03). Reductions in blood pressure (5.6/2.7 mm Hg)...

Background: The prevalence of obesity amongst women bearing children in Australia is rising and has important implications for obstetric care. The aim of this study was to assess the prevalence and impact of mothers being overweight and obese in early to mid-pregnancy on maternal, peripartum and neonatal outcomes. Methods: A secondary analysis was performed on data collected from nulliparous women with a singleton pregnancy enrolled in the Australian Collaborative Trial of Supplements with antioxidants Vitamin C and Vitamin E to pregnant women for the prevention of pre-eclampsia (ACTS). Women were categorized into three groups according to their body mass index (BMI): normal (BMI 18.5-24.9 kg/m2); overweight (BMI 25-29.9 kg/m2) and; obese (BMI 30-34.9 kg/m2). Obstetric and perinatal outcomes were compared by univariate and multivariate analyses. Results: Of the 1661 women included, 43% were overweight or obese. Obese women were at increased risk of pre-eclampsia (relative risk (RR) 2.99 [95% confidence intervals (CI) 1.88, 4.73], p < 0.0001) and gestational diabetes (RR 2.10 [95%CI 1.17, 3.79], p = 0.01) compared with women with a normal BMI. Obese and overweight women were more likely to be induced and require a caesarean section compared with women of normal BMI (induction - RR 1.33 [95%CI 1.13...

PCOS (polycystic ovary syndrome) is associated with reproductive abnormalities, IR (insulin resistance) and elevated risk factors for CVD (cardiovascular disease) and Type 2 diabetes, including endothelial dysfunction. The present study aimed to assess a range of circulating markers of endothelial function in overweight women with and without PCOS. Overweight and obese age- and BMI (body mass index)-matched women with (n=80) and without (n=27) PCOS were assessed in a cross-sectional study. End-point measures were HOMA (homoeostasis model assessment)-IR, androgens, lipids, inflammatory markers [hsCRP (high-sensitivity C-reactive protein)] and endothelial function [FMD (flow-mediated dilation), ADMA (asymmetric dimethylarginine), PAI-1 (plasminogen activator inhibitor-1) and vWF (von Willebrand factor)]. Women with PCOS had elevated HOMA-IR (4.1±3.4 compared with 1.9±1.4), free androgen index (9.3±5.6 compared with 4.6±3.8), total cholesterol (5.2±1.0 compared with 4.7±0.9 mmol/l) and triacylglycerols (triglycerides; 1.4±0.7 compared with 0.9±0.3 mmol/l) (P<0.05 for all), but similar hsCRP compared with women without PCOS. With regard to endothelial function, women with PCOS had elevated ADMA (1.0±0.4 compared 0.3±0.1 μmol/l...

BACKGROUND: Polycystic ovary syndrome (PCOS) is associated with hyperandrogenism and an increased risk of Type 2 diabetes and cardiovascular disease. Decreased SHBG and elevated testosterone are associated with metabolic syndrome and glucose intolerance in women. AIM: The aim of this study was to assess the relationship between SHBG and testosterone and metabolic syndrome and glucose intolerance in PCOS. MATERIAL/SUBJECTS AND METHODS: Cross-sectional study in overweight and obese premenopausal non-diabetic women with PCOS (no.=178: no.=55 metabolic syndrome, no.=16 glucose intolerance). Data were analyzed by multiple regression with metabolic syndrome, oral glucose tolerance test (OGTT) glucose or SHBG as dependent variables and reproductive hormones, insulin resistance, glucose tolerance, lipids or C-reactive protein as independent variables. RESULTS: Metabolic syndrome was independently associated with body mass index [odds ratio (OR) 1.084 95% confidence interval (CI) 1.034-1.170, p=0.015] and SHBG (OR 0.961 95% CI 0.932-0.995, p=0.018). Glucose tolerance was independently associated with OGTT insulin (β=0.418, p<0.001), age (β=0.154, p=0.033) and PRL (β=-0.210, p=0.002). SHBG was independently associated with OGTT insulin (β=-0.216...

There are several barriers related to the non-accomplishment of the dietary treatment of overweight. Social desirability (SD), defined as the tendency to transmit a culturally accepted image, may bias parameters evaluated in scientific studies.(1) To evaluate SD in overweight women; (2) To evaluate the association between SD and other characteristics; (3) To compare the level of SD between patients evaluated in their first appointment or in subsequent appointments; (4) To evaluate the differences in the level of SD between patients who mention or not each barrier to the accomplishment of the dietary treatment; (5) To evaluate the effect of SD in the frequency of each statement pointed out as a barrier to the accomplishment of the dietary treatment.Sixty-seven women with BMI over 25,0 kg/m2 (mean BMI = 40,0 kg/m2; sd= 5,7) and mean age of 40 years (sd = 11) were evaluated on age, education, height, present and desired weights, perception of heath condition, weight and body image (Likert scale from 1 feels very well to 5 very bad). BMI, weight they desired to loose and corresponding BMI were calculated. The number of previous appointments and the date of the first appointment were registered and the time since the first appointment was calculated. Psychopathologic characteristics were studied with the Psychological General Well-Being Index. Barriers to the accomplishment of the dietary treatment were evaluated by pointing...

This study presents the nutrient data collected from women who were being screened for premenstrual syndrome (PMS) for entry into an intervention study. Screening was by the Steiner self-rated questionnaire. One hundred and forty-four overweight women completed the screening process and eighty-eight met the criteria for PMS. All women kept 4 d diet diaries pre- and postmenstrually over two menstrual cycles. The mean energy and macronutrient intakes were compared between the pre- and postmenstrual phases. Energy and macronutrient intake was also calculated according to food categories. Goldberg's cut-off limit for the ratio of energy intake to estimated basal metabolic rate was used to exclude data that was incompatible with predicted energy requirements. The diet diaries were also used to determine the mean number of meals or snacks eaten pre- and postmenstrually. Nutrient analysis of the diet diaries of the women with PMS showed a significant increase (P<0.001) in total energy and all macronutrients premenstrually when compared to nutrient intake postmenstrually. Women who did not meet the criteria for PMS showed a significant increase in energy and fat intake (P<0.05) but not in the other macronutrients. When adjusted for energy...

The reasons for exercising that are featured in health communications brand exercise and socialize individuals about why they should be physically active. Discovering which reasons for exercising are associated with high-quality motivation and behavioral regulation is essential to promoting physical activity and weight control that can be sustained over time. This study investigates whether framing physical activity in advertisements featuring distinct types of goals differentially influences body image and behavioral regulations based on self-determination theory among overweight and obese individuals. Using a three-arm randomized trial, overweight and obese women and men (aged 40–60 yr, n = 1690) read one of three ads framing physical activity as a way to achieve (1) better health, (2) weight loss, or (3) daily well-being. Framing effects were estimated in an ANOVA model with pairwise comparisons using the Bonferroni correction. This study showed that there are immediate framing effects on physical activity behavioral regulations and body image from reading a one-page advertisement about physical activity and that gender and BMI moderate these effects. Framing physical activity as a way to enhance daily well-being positively influenced participants' perceptions about the experience of being physically active and enhanced body image among overweight women...

DOI: http://dx.doi.org/10.5007/1980-0037.2014v16n1p58 The aim of this study was to investigate the prevalence of body image perception and its association with anthropometric indicators (body mass index, waist circumference, waist-height ratio, and conicity index) in women undergoing cervical cancer screening at an institution in Florianópolis, Santa Catarina. The study included 736 women (≥ 18 years). Anthropometric variables (weight, height, waist circumference) were collected for the determination of body mass index, waist-height ratio, and conicity index. Body image perception was evaluated using a nine-body silhouette scale. The prevalence of body image dissatisfaction was 73% (dissatisfaction due to excess weight = 67.4%; dissatisfaction due to thinness = 5.6%). Overweight women (PR=1.34; 95%CI=1.23-2.49, p<0.001) and women with an inadequate conicity index (PR=1.12; 95%CI =1.02-1.24, p=0.016) presented a higher prevalence of body image dissatisfaction. The prevalence of body image dissatisfaction is high and the proportion of inadequate anthropometric indicators requires attention. Moreover, body dissatisfaction was more prevalent among overweight women and women with an inadequate conicity index. These results indicate the need for interventions and for the implementation of programs designed to control body weight and to reduce cardiovascular risk factors and body image dissatisfaction in women attending primary health care centers...
