Background:African-Americans lose less weight during a behavioral intervention compared with Whites, which may be from differences in dietary intake or physical activity.Methods:Subjects (30% African American, 70% White; n = 346; 42.4 ± 9.0 yrs.; BMI = 33.0 ± 3.7 kg/m2) in an 18-month weight loss intervention were randomized to a standard behavioral (SBWI) or a stepped-care (STEP) intervention. Weight, dietary intake, self-report and objective physical activity, and fitness were assessed at 0, 6, 12, and 18 months.Results:Weight loss at 18 months was greater in Whites (–8.74 kg with 95% CI [–10.10, –7.35]) compared with African Americans (–5.62 kg with 95% CI [–7.86, –3.37]) (P = .03) in the SBWI group and the STEP group (White: –7.48 kg with 95% CI [–8.80, –6.17] vs. African American: –4.41kg with 95% CI [–6.41, –2.42]) (P = .01). Patterns of change in dietary intake were not different between groups. Objective physical activity (PA) changed over time (P < .0001) and was higher in Whites when compared with African Americans (P = .01).Conclusions:Whites lost more weight (3.10 kg) than African American adults. Although there were no differences in dietary intake, Whites had higher levels of objective PA and fitness. Thus, the discrepancy in weight loss may be due to differences in PA rather than dietary intake. However, the precise role of these factors warrants further investigation.

A review of 47 studies evaluating the occurrence of metabolic syndrome among employees of different professional groups around the world was made. The influence of various factors of the professional environment (physical activity in the workplace, exposure to occupational stress, exposure to harmful toxicants) on the frequency of the syndrome and its components, considering gender, age and work experience. Analysis of the literature has shown that the characteristics of work activity affect the formation of the syndrome along with well - known risk factors-lifestyle, gender and age. Thus, in most cases, the frequency of metabolic syndrome in people who have mostly "sedentary" work is much higher than in other professional groups. It is proved that the risk of the syndrome is increased when exposed to certain chemicals that are in the air of the work area, even in small concentrations, as well as under unfavorable conditions of activity - shift work, night duty, professional stress. To improve the quality of life of employees and reduce economic and social costs, it is necessary to develop programs for the prevention and rehabilitation of people with this pathology, taking into account specific working conditions, while making adjustments for gender, age, social factors (smoking status, alcohol consumption, eating behavior, physical activity during and outside of work).

Background and objective: Managing the decrease in physical function in the elderly is a major task in aging societies globally. Here, we aimed to compare the physical function and metabolic syndrome (MetS) risk factors according to levels of physical activity (PA). Material and methods: We measured PA in 77 elderly Korean men (74.21 ± 6.26 years old) with an accelerometer and recorded body composition, physical function, and MetS-related risk factors. Participants were divided into three groups based on daily moderate-vigorous physical activity (MVPA): low (under 60 min), middle (60-120 min), and high (over 120 min). The groups were compared using a one-way analysis of variance and the Scheffe post hoc test. Odds ratios (OR) were calculated by logistic regression analysis. Results: Significant differences were found between the groups for sedentary behavior time (P < 0.001), light PA (P < 0.05), moderate PA (P < 0.001), vigorous PA (P < 0.05), and total energy expenditure (P < 0.001). The high PA group showed a significantly lower percentage of body fat and fat mass and higher muscle mass than did the low and middle PA groups (P < 0.05). The 6-min walk test was significantly better in the high PA group than in the low and middle PA groups (P < 0.05). Grip strength and the Berg balance scale were also significantly better in the high PA group (P < 0.05). Bone mineral density (BMD) and high-density lipoprotein cholesterol (HDL-C) were significantly higher in the high PA group than in the low PA group (P < 0.05). Systolic blood pressure (SBP) was significantly higher in the middle PA group than in the low PA group (P < 0.05). Participants with more than three MetS criteria showed an OR of 0.09 (95% confidence interval 0.01-0.82) in the high PA group as compared with the low PA group (P < 0.05). Conclusions: Moderate-vigorous physical activity of more than 120 min daily showed better physical function and lower OR of MetS than did lower MVPA levels in elderly Korean men.
