ObjectiveAs overall spread of obesity in populations is generally acknowledged to result from unhealthy lifestyles rather than individual genetic makeup, this study aimed to gain specific insights into its determinants through assessing the prevalent associations between individual socioeconomic status (SES) and weight loss in overweight and obese men and women.MethodsA prospective, 2-year follow-up study covered 3362 (38.0% men) respondents, aged 43–64 years, body mass index ≥25 kg/m2. Changes in body weight were estimated as a percentage of initial weight. Three categories of changes were defined: gained ≥3%, stable (gained <3% or lost <3%), lost ≥3%. Body weight loss was determined against three categories: lost ≥3 to <5%, lost ≥5 to <10%, lost ≥10%. Select SES variables (ie, gender, age, education, marital status, occupational activity and income) were determined in line with the Health Status Questionnaire. The associations between SES and body weight changes were analysed with the aid of logistic regression models. The results were presented as ORs with 95% CIs.ResultsOnly 18% of the respondents had complied with the medical recommendations on weight loss. Significant differences were encountered between the gender, age and occupational activity variables and the weight loss one. Multifactorial models were used to determine the following gender-specific associations between SES and weight loss. Men with moderate income had significantly higher odds for weight loss (≈75%), as compared with the higher earners, whereas women with low income, occupationally inactive, had significantly higher odds (≈30% and ≈50%, respectively), as compared with the high earners and occupationally active ones.ConclusionsLower education, male gender, lower income per household, older age and unemployment status were the established factors predisposing to obesity. While aiming to ensure effectiveness of the measures specifically aimed at preventing obesity, population groups deemed most at risk of potential weight gain must prior be identified.

Abstract Background Patients with type 2 diabetes (T2D) may experience frequent body weight changes over time. The prognostic impact of these weight changes (gains or losses) requires further study. Aims To study the associations between changes in body weight (intentional or unintentional) with subsequent outcomes. Methods The EXAMINE trial included 5380 patients with T2D and a recent acute coronary syndrome, who were randomized to alogliptin or placebo. Time-updated Cox models and mixed effects models were used to test the associations between changes in body weight and subsequent outcomes over a median follow-up of 1.6 (1.0–2.1) years. Results During the post-randomization follow-up period, 1044 patients (19.4%) experienced a weight loss ≥ 5% of baseline weight, 2677 (49.8%) had a stable weight, and 1659 (30.8%) had a ≥ 5 % weight gain. Patients with weight loss were more frequently women and had more co-morbid conditions. In contrast, patients who gained ≥ 5% weight were more frequently men with less co-morbid conditions. A weight loss ≥ 5% was independently associated with a higher risk of subsequent adverse outcomes, including all-cause mortality: adjusted HR (95% CI) = 1.79 (1.33–2.42), P < 0.001. Similar associations were found for cardiovascular mortality, the composite of cardiovascular mortality or heart failure hospitalization, and the primary outcome. A weight gain ≥ 5% was independently associated with an increase in the risk of subsequent cardiovascular mortality or heart failure hospitalization only: adjusted HR (95% CI) = 1.34 (1.02–1.76), P = 0.033. Conclusions In patients with T2D who had a recent ACS/MI, a ≥ 5% loss of body weight was associated with a higher risk of subsequent cardiovascular events and mortality.

Body Weight Changes

Food intake and body weight changes in response to induction of acute inflammation were examined in intact cycling females, ovariectomized females, and sham-operated male rats. In intact females, body weight and feeding responses were compared between rats in which inflammation was induced on day of estrus with rats in which inflammation was induced on day of diestrus. Anorexia and weight loss were more severe in the female rats with inflammation induced on estrus day, which coincides with peak serum estrogen levels. In ovariectomized females, inflammation was induced the day after rats received injections of estrogen, progesterone, or sesame oil (vehicle). Males received vehicle injections. Among female rats, the group that received estradiol injections the previous day displayed the most severe anorexia. The least severe anorexia was observed in female rats that received progesterone the previous day. Food intake of female rats that received vehicle injections prior to induction of inflammation was greater than the rats receiving estrogen but less than the rats receiving progesterone. Male rats displayed the most severe anorexia and greatest weight loss. These data suggest that, although females exposed to estradiol prior to induction of acute inflammation display more severe anorexia than those exposed to progesterone, it may be that progesterone attenuates severity of anorexia rather than estrogen solely potentiating severity. Male rats, however, appear to experience the most severe anorexia in response to this form of inflammation.

Aims. To study of the polymorphisms of the TPN2 and GNB3 genes in obese patients and their effect on weight loss in patients on sibutramine therapy. Materials and methods. The research study included 118 patients with exogenous-constitutional obesity who received Reduxin (sibutramine + CMC) at the dose of 10 mg. Term follow-up was 3 months. A genetic study was performed to assess ТРН2 and GNB3 gene polymorphisms. The response to the therapy was evaluated after 3 months by the dynamics of body weight. Results. In the study the G703T polymorphism of the GNB3 gene showed that during 3 months of observation, carriers of the TT genotype had a greater decrease in body weight in comparison with carriers of the allele C -8 kg (-12; -5) vs. -5 kg (-8; -3), p = 0.018. In carriers of different variants of the genotype of the TPH2 gene (polymorphism C825T), there was no difference in body weight dynamics with sibutramine therapy. There was no correlation between the foresaid polymorphisms of the TPH2 and GNB3 genes with the indices of blood pressure and heart rate. Conclusions. 1. The result of sibutramin therapy may depend on genetic factors: in carriers of the TT-genotype C825T of the GNB3 gene the body weight loss was higher than among the carriers of the C allele. 2. Changes in blood pressure and heart rate did not show any statistically significant relationship with polymorphisms of the TPH2 and GNB3 genes.

Abstract Background: Recent research has demonstrated that Type 2 Diabetes (T2D) risk is influenced by a number of common polymorphisms, including rs17782313 MC4R, rs1801282 PPARG, and rs7903146 TCF7L2. Knowledge of the association between these SNPs (single nucleotide polymorphism) and body weight changes in different forms of prediabetes treatment is still limited. The aim of this study was to investigate the association of polymorphisms within the MC4R, PPARG, TCF7L2 genes on the risk of carbohydrate metabolism disorders and body composition changes in overweight or obese patients with early carbohydrate metabolism disorders. Methods and Results: From 327 patients, a subgroup of 81 prediabetic female patients (48.7±14.8 years) of Eastern European descent participated in a 3-month study comprised of diet therapy or diet therapy accompanied with metformin treatment. Bioelectrical impedance analysis and genotyping of rs17782313 MC4R, rs7903146 TCF7L2, rs1801282 PPARG were performed. The MC4R CC and TCF7L2 TT genotypes were associated with increased risk of T2D (OR=1.46, p=0.05 and OR=2.47, p=0.006, respectively). PPARG СС homozygotes experienced increased weight loss; however, no additional improvements were experienced with the addition of metformin. MC4R ТТ homozygotes who took metformin alongside dietary intervention experienced increased weight loss and reductions in fat mass (p<0.05).Conclusions: We confirmed the previous association of the MC4R C and TCF7L2 T alleles with T2D risk. The obesity-protective alleles (MC4R T and PPARG C) were positively associated with weight loss efficiency.

Abstract The study was aimed at comparing pacing adopted by males and females in a 107-km mountain ultramarathon and assessing whether pacing-related variables were associated with intracompetition body weight changes and performance. Forty-seven athletes (29 males; 18 females) were submitted to a cardiopulmonary exercise test before the race. Athletes were also weighted before the start of the race, at three midpoints (33 km, 66 km and 84 km) and after the race. Pacing was analyzed using absolute and relative speeds and accelerometry-derived sedentary time spent during the race. Results showed that females spent less sedentary time (4.72 ± 2.91 vs. 2.62 ± 2.14%; p = 0.035; d = 0.83) and displayed a smaller body weight loss (3.01 ± 1.96 vs. 4.37 ± 1.77%; p = 0.048; d = 0.77) than males. No significant sex differences were revealed for speed variability, absolute and relative speed. In addition, finishing time was correlated with: speed variability (r = 0.45; p = 0.010), index of pacing (r = -0.63; p < 0.001) and sedentary time (r = 0.64; p < 0.001). Meanwhile, intracompetition body weight changes were related with both the absolute and relative speed in the first and the last race section. These results suggest that females, as compared with males, take advantage of shorter time breaks at aid stations. Moreover, performing a more even pacing pattern may be positively associated with performance in mountain ultramarathons. Finally, intracompetition body weight changes in those races should be considered in conjunction with running speed fluctuations.
