Physical Activity, Weight, and Waist Circumference in Midlife Women
During midlife years, women are at risk of increasing body weight and waist circumference. We evaluated changes in weight and waist circumference from enrollment to 2 years later and examined the influence of physical activity level on those changes among 232 women aged between 40 and 50. Weight increased significantly for the entire sample. Those who increased their physical activity from enrollment to 2 years later had the smallest increase in weight and had a slight decrease in waist circumference. To maintain ideal weight and waist circumference, midlife women should be encouraged to increase physical activity before and during the menopausal transition.

- "Okura et al. (2005) also demonstrated with a group of pre and postmenopausal women that 10 weeks of nutritional control and step classes were enough to reduce visceral adipose tissue. Choi et al. (2012) analyzed the body mass and the WC in 232 women between 40 and 50 years old during 2 years; they found a slight reduction of WC in those who increased their physical activity. Authors suggest that women must be motivated to do more physical activity before and after menopause. "

ABSTRACT: Changes in body composition in postmenopausal women, such as increases in visceral and abdominal adipose tissue, show metabolic and cardiovascular diseases. Twenty-one postmenopausal women participated in an Aquagym program during 16 weeks. The variables analyzed included measuring waist circumference (WC), hip circumference (HC), waist-hip ratio (WHR), sagittal abdominal diameter (SAD) and intra-abdominal adipose tissue (IAAT). Statistical treatment was a t test used to compare groups, and Goodman’s test was used to analyze changes in the qualitative classification of the WHR. Significant reductions (p≤0.05) were obtained in all variables measured after the exercise intervention. Aquagym program was able to reduce the abdominal and visceral adipose tissue, and to decrease the risk of developing metabolic and cardiovascular diseases, at the same time is is an effective strategy to deal with central obesity.

ABSTRACT: To study some psycho-social variables in a sample of non-weight loss treatment-seeking overweight adults and to evaluate the weight outcome and the possible risk factors for weight gain over a 1-year period.
167 Overweight (BMI range 25-29.9) subjects (66 % females, age 50 ± 10 years, BMI 28 ± 1.49) were recruited randomly in the surgeries of primary care physicians (PCPs). Data were collected through an ad hoc questionnaire with personal details and medical history. The following tests were administered: Binge Eating Scale (BES), Beck's Depression Inventory (BDI) and Body Uneasiness Test (BUT). Weight and height were measured using a mechanical balance with a stadiometer in standard conditions. At follow-up, 1 year after, updated data were collected for 125 subjects (75 %).
At follow-up, there was remarkable weight instability: only 16 % of the subjects maintained their baseline weight, 40.8 % showed a decrease, and 43.2 % gained weight. In 14.4 % of cases, weight gain led to obesity (BMI ≥30). 18 individuals (14.4 %) reported having followed weight loss treatments in the last year, 11 among people with stable/decreased weight and 7 among those with weight gain. Lifetime comorbidity for anxiety and intense body uneasiness at baseline were the most important factors significantly associated with weight gain. Living with someone and habitually practicing sport resulted to play a protective role against weight increase.
Our study highlights the importance of a multidimensional assessment (medical and psycho-social) of overweight patients, aimed to identify individuals at greater risk of weight gain. They should receive targeted interventions.

ABSTRACT: Preventing physical inactivity and weight gain during college is critical in decreasing lifelong
obesity and associated disease risk. As such, we sought to compare cardiometabolic risk factors and lifestyle behaviours between college students enrolled in Kinesiology and non-Kinesiology degree programs. Anthropometrics, fasting blood glucose, insulin, lipid profiles and HbA1c%, blood pressure, and peak oxygen consumption (VO2peak) were assessed in 247 healthy college students. The homeostasis model assessment of insulin sensitivity (HOMA) was calculated using glucose and insulin levels. Self-reported physical activity from the Paffenbarger questionnaire was collected to estimate the average caloric expenditure due to different types physical activities. Despite no significant differences in BMI or waist circumference between groups, Kinesiology majors presented with ~20% lower fasting insulin levels and HOMA (p=0.01; p<0.01, respectively) relative to non-majors. Kinesiology majors reported increased weekly participation in vigorous intensity sport and leisure activities and, on average, engaged in >300 MET-hr/wk, while non- Kinesiology majors engaged in <300 MET-hr/wk. (p=0.01). Our data suggests that students enrolled in Kinesiology degree programs display improved healthy behaviours and associated outcomes (parameters of glucose homeostasis). Practical outcomes of
this research indicate that implementing components of a comprehensive Kinesiology curriculum encourages improved health behaviours and associated cardiometabolic risk factors.
