Yogurt consumption, body composition, and metabolic health in the Québec Family Study

The present study longitudinally evaluated growth, bone mineral density, body composition, and metabolic health outcome in very low birth weight (VLBW) infants whose in-hospital target nutrient intake was within recent recommendations. From six months to three years, bone mineral density (dual-energy X-ray absorptiometry, DXA), body composition, and metabolic health outcome were compared with a reference group of term infants. The aim was to test whether in-hospital achieved weight gain until 36 weeks of gestation (light or appropriate for term equivalent age; LTEA or ATEA) predicts later growth, bone mineral density (BMD), abdominal obesity, or metabolic health outcomes such as insulin resistance, relative to term infants, during the first three years of life. Target in-hospital energy and protein intake was not achieved. Growth in weight, length and head circumference, mid arm circumference, adiposity, fat free mass (FFM), and bone mineralization in VLBW infants was less than those in term infants and influenced by nutritional status at discharge. Preterm infants had poorer motor and cognitive outcomes. Post-discharge body composition patterns indicate FFM proportional to height but lower fat mass index in LTEA preterm infants than term infants, with no evidence of increased truncal fat in preterm infants. The hypothesis of early BMD catch-up in VLBW infants after discharge was not supported by the present data. The clinical significance of these findings is unclear. The data may suggest a reduced obesity risk but an increased osteoporosis risk. Since postnatal growth restriction may have permanent negative health effects, LTEA VLBW infants would especially appear to benefit from targeted preventive interventions. Further follow-up of the infants is required.

Background: Body composition is known to differ across metabolic health and weight phenotypes. Regular exercise improves body composition, yet little is known about differences in exercise response across metabolic health and weight phenotypes. Methods: Normal weight (n=376) and overweight/obese (OWOB) adults (n=456) from the HERITAGE Family Study (56% female, 38% Black) completed a 20-week endurance training program. Four groups based on baseline BMI and metabolic risk were created: metabolically healthy normal weight, MHNW; metabolically unhealthy normal weight, MUNW; metabolically healthy OWOB, MHO; and metabolically unhealthy OWOB, MUO. Unhealthy was defined as having ≥2 metabolic syndrome components. General linear models tested for differences in baseline and change in measures of body composition (fat mass [FM], fat-free mass [FFM], % body fat [%BF], visceral fat) after adjusting for age, sex, and ethnicity (and baseline value in change models). Results: Table 1 shows adjusted mean baseline and change in body composition values by group. Baseline body composition tended to track with weight status, with NW adults having lower FM, %BF, and visceral fat compared to obese adults (p<0.05), regardless of metabolic health. However, the MHO group had lower baseline values of these traits compared to MUO (p<0.05). Body composition measures significantly improved with exercise training in all groups, however, the magnitude of change differed between groups. For example, both NW groups had larger decreases in %BF compared to the obese groups, with MUNW showing the largest decrease. Conversely, MHNW showed the largest decrease in visceral fat, which was greater than both obese groups, but change in visceral fat was similar between MHO and MUNW. Conclusions: Normal weight adults tended to have better body composition profiles at baseline and larger improvements with exercise compared to obese adults, regardless of metabolic health. Within weight groups, body composition improved regardless of metabolic health status.

Abstract Polycystic ovary syndrome (PCOS) is a common and complex endocrinopathy with reproductive and metabolic manifestations, carrying a major health and economic burden. Exercise training has consistently been found improve clinical outcomes in women with PCOS, but shortfalls with exercise prescription are evident. Research suggests that high intensity intermittent exercise (HIIT) is feasible, well tolerated and enjoyable for people with or at risk of chronic disease and can address many of the shortfalls and barriers to exercise participation. To investigate the effects of high intensity exercise, twenty-four reproductive aged, overweight and obese, previously sedentary women with PCOS were recruited from the community and randomised to complete either 12 weeks of moderate intensity continuous cycling exercise (MOD; 50-60% of maximal heart rate [HRmax]; n=11) or HIIT (90-95% HRmax; n=13). All exercise was supervised by an exercise physiologist and completed 3 times per week on a cycle ergometer. Baseline and post testing measures consisted of peak oxygen consumption (VO2peak) determine by a graded maximal exercise test, insulin sensitivity determined by hyperinsulinaemic-euglycaemic clamp, body composition outcomes and anti-mullerian hormone (AMH). Enjoyment was also measured throughout the intervention using feeling scales. Significant improvements were seen for VO2peak after HIIT with an average increase of 5.6 ± 2.5 mL.kg-1.min-1 (P=0.013) and non-significant increases in the MOD group (3.4 ± 2.1 mL/kg/min; P=0.20). Body composition, fasting insulin and AMH values remained unchanged in both groups. Non-significant improvements in glucose infusion rate (3.3 ± 2.8 mg.lbmkg-1.min-1; P=0.06) and insulin sensitivity index (M-to-I ratio; 3.0 ± 3.8 mg.lbmkg-1.min-1[mU/I]-1 x 100; P=0.17) were found as a result of HIIT compared to no changes after moderate intensity exercise. Importantly, HIIT was also found to be more enjoyable than moderate intensity continuous exercise. The present study is the first to compare current exercise recommendations of moderate and vigorous intensities in women with PCOS. The results of this study provide preliminary validation of HIIT and should be considered for improving cardio-metabolic health in women with PCOS.
