Here, we carried out a longitudinal 1-year follow-up study to evaluate the effect of urbanization, an important determinant of health, on metabolic profiles of young Indonesian adults. University freshmen/women in Jakarta, aged 16-25 years, who either had recently migrated from rural areas or originated from urban settings were studied. Anthropometry, dietary intake, and physical activity, as well as fasting blood glucose and insulin, leptin, and adiponectin were measured at baseline and repeated at one year follow-up. At baseline, 106 urban and 83 rural subjects were recruited, of which 81 urban and 66 rural were followed up. At baseline, rural subjects had better adiposity profiles, whole-body insulin resistance, and adipokine levels compared to their urban counterparts. After 1-year, rural subjects experienced an almost twice higher increase in BMI than urban subjects (estimate (95%CI): 1.23 (0.94; 1.52) and 0.69 (0.43; 0.95) for rural and urban subjects, respectively, P-int < 0.01). Fat intake served as the major dietary component, which partially mediates the differences in BMI between urban and rural group at baseline. It also contributed to the changes in BMI over time for both groups, although it does not explain the enhanced gain of BMI in rural subjects. A significantly higher increase of leptin/adiponectin ratio was also seen in rural subjects after 1-year of living in an urban area. In conclusion, urbanization was associated with less favorable changes in adiposity and adipokine profiles in a population of young Indonesian adults. Show less

Show moreBackground: Overweight is a common problem in Duchenne muscular dystrophy (DMD) and is associated with reduced mobility and quality of life. The influence of nutritional intake on (over)weight is unclear.Objective: To investigate weight and energy and macronutrients intake compared to age-specific requirements in DMD patients (4-18 years).Methods: We assessed weight and body mass index (BMI) and the amount of energy (kcal/day) and macronutrients based on self-reported nutrition diaries. Nutritional intake was compared to requirements for 3 age-groups according to the Dutch Healthy Diet Guideline (4-8/9-13/14-18 years) using a student's t-test, and relations with age and BMI were investigated by means of Pearson's correlations.Results: Forty-eight patients participated, 22 ambulatory, median age 10.8 years. The majority used corticosteroids (N = 41). Overweight (BMI z-score > 2.07) was present in 19 patients; 6% (4-8 years), 73% (9-13 years) and 47% (14-18 years). Overweight was more common in non-ambulatory (61.6%) than ambulatory patients (13.6%). Patients aged 4-8 received 290 kcal/day more than required (p < 0.001). Patients aged 9-13 received 349 kcal/day (p = 0.005) less than required. Overall, intake of fibre, nuts, meat/fish/eggs/legumes and dairy was lower than recommended (p < 0.05). The difference between energy intake versus requirement correlated moderately to age (r = -0.549, p < 0.001) and BMI (r = -0.562, p < 0.001).Conclusions: Overweight was found especially in patients aged 9-18 even though they received less energy than required. Younger patients (4-8) had good weight but consumed more energy than required. All patients did not consume enough fibre, nuts, meat/fish/eggs/legumes and dairy. Limiting energy and increasing fibre/protein intake at an early age may prevent overweight at a later age. Show less

Show moreRecent studies indicate that the timing of food intake can significantly affect metabolism and weight management. Workers operating at atypical times of the 24-h day are at risk of disturbed feeding patterns. Given the increased risk of weight gain, obesity and metabolic syndrome in shift working populations, further research is required to understand whether their eating behavior could contribute to these increased metabolic risks. The objective of this study was to characterize the dietary patterns of police officers across different types of shifts in their natural environments. Thirty-one police officers (six women; aged 32.1 +/- 5.4 years, mean +/- SD) from the province of Quebec, Canada, participated in a 28- to 35-day study, comprising 9- to 12-h morning, evening, and night shifts alternating with rest days. Sleep and work patterns were recorded with actigraphy and diaries. For at least 24 h during each type of work day and rest day, participants logged nutrient intake by timestamped photographs on smartphones. Macronutrient composition and caloric content were estimated by registered dieticians using the Nutrition Data System for Research database. Data were analyzed with linear mixed effects models and circular ANOVA. More calories were consumed relative to individual metabolic requirements on rest days than both evening- and night-shift days (p = 0.001), largely sourced from increased fat (p = 0.004) and carbohydrate (trend, p = 0.064) intake. Regardless, the proportions of calories from carbohydrates, fat, and protein did not differ significantly between days. More calories were consumed during the night, between 2300 h and 0600 h, on night-shift days than any other days (p < 0.001). Caloric intake occurred significantly later for night-shift days (2308 h 0114 h, circular mean +/- SD) than for rest days (1525 h +/- 0029 h; p < 0.01) and was dispersed across a longer eating window (13.9 h 3.1 h vs. 11.3 h +/- 1.8 h, mean +/- SD). As macronutrient proportions were similar and caloric intake was lower, the finding of later meals times on night-shift days versus rest days is consistent with emerging hypotheses that implicate the biological timing of food intake-rather than its quantity or composition-as the differentiating dietary factor in shift worker health.
