“…This could be because the effects of diet and activity on body fat distribution are the result of cumulative exposure to established patterns over time. In particular, fat becomes more centrally distributed as people get older [ 50 - 52 ]. The APCAPS population may therefore be too young (mean age 21) to detect the associations that are seen in the older IMS population.…”

BackgroundObesity is a growing health problem in India and worldwide, due to changes in lifestyle. This study aimed to explore the independent associations between dietary and physical activity exposure variables and total body fat and distribution in an Indian setting.MethodsIndividuals who had participated in the Indian Migration Study (IMS) or the Andhra Pradesh Children And Parents' Study (APCAPS), were invited to participate in the Hyderabad DXA Study. Total and abdominal body fat of study participants was measured using DXA scans. Diet and physical activity (PA) levels were measured using questionnaires.ResultsData on 2208 participants was available for analysis; mean age was 49 yrs in IMS, 21 yrs in APCAPS. Total energy intake was positively associated with total body fat in the APCAPS sample: a 100 kcal higher energy intake was associated with 45 g higher body fat (95% CI 22, 68). In the IMS sample no association was found with total energy intake, but there was a positive association with percent protein intake (1% higher proportion of energy from protein associated with 509 g (95% CI 138,880) higher total body fat). Broadly the same pattern of associations was found with proportion of fat in the abdominal region as the outcome. PA was inversely associated with total body fat in both populations (in APCAPS, one MET-hour higher activity was associated with 46 g (95% CI 12, 81) less body fat; in the IMS it was associated with 145 g less body fat (95% CI 73, 218)). An inverse association was observed between PA and percentage abdominal fat in the IMS but no association was seen in the APCAPS population.ConclusionsIn this Indian population, there was an inverse association between PA and body fat. Associations between body fat and dietary variables differed between the younger APCAPS population and older IMS population. Further longitudinal research is needed to elucidate causality and directions of these associations across the life course.Electronic supplementary materialThe online version of this article (doi:10.1186/s12889-015-1550-7) contains supplementary material, which is available to authorized users.

“…Sugihara et al [30] concluded that VAT is positively correlated with age in all of the BMI strata in both genders. Another cross-sectional investigation [31], which included 130 participants and assessed VAT by computed tomography, clearly showed that VAT increased by 2.43 cm 2 each year. In this study, 1 year of increasing age was associated with a mean VAT increase of 2.28 cm 2 .…”

BackgroundThe Czech Republic lacks body composition data for women. Therefore, the purpose of the study was to analyze body composition [body fat mass (BFM), fat-free mass (FFM), body fat percentage (%BFM) and visceral adipose tissue (VAT)] and to evaluate the changes that occur with aging in women aged 18–89 years. We also analyzed anthropometric characteristics of study participants and developed age-specific percentile curves for body composition parameters.MethodsA cross-sectional, non‐randomized study was conducted with a sample of 1,970 apparently healthy Czech women. Body composition was measured using a direct segmental multi-frequency bioelectrical impedance analysis (BSM-BIA).ResultsThe mean BFM was 19.7 ± 8.9 kg, and BFM reached its peak in women over 70, at 27.6 ± 8.8 kg. There was a strong correlation between BFM and age (r = 0.61; r2 = 0.37). Fifty percent of the women in the study had a BFM between 13.0 and 25.0 kg. The %BFM (r = 0.69; r2 = 0.47) and VAT (r = 0.88; r2 = 0.77) were also significantly associated with age. The reference range for %BFM was 22.0–35.6 % (25th–75th percentile). The mean FFM was 45.8 ± 5.5 kg, and FFM decreased with age (r = −0.27; r2 = 0.07).ConclusionsThe results presented in this study showed a statistically significant increase in BFM, %BFM and VFA as age increased, and the values reached their peak in women over 70. Even when FFM decreased slightly with age, body weight increased because of the increase in BFM.

“…Redline et al [7] similarly reported in a longitudinal follow-up study that the AHI increase was highest in the 41-54-year group. Even when the body weight remains unchanged, increases in visceral fat [26] and pharyngeal fat during middle age can increase the amount of pharyngeal tissue [27], which may increase the occurrence of respiratory events. The association between mild to moderate OSAS severity and the AHI increase presently observed is consistent OR odds ratio, CI confidence interval, AHI apnoea-hypopnoea index, BMI body mass index, CPAP continuous positive airway pressure, NS not significant with previous reports [4,7].…”

“…Furthermore, the impact of central obesity also could not be evaluated. Increases of visceral fat during middle age can increase the amount of pharyngeal tissue, which may heighten the occurrence of respiratory events [26,27]. To elucidate the mechanism underlying the worsening of AHI and SpO 2 in middle-aged patients, further study evaluating the waist or neck circumference is needed.…”
