Objective: To investigate the effect of fat mass and fat-free mass on bone mineral density (BMD) in pre- and postmenopausal women.
Methods: 282 premenopausal women with regular menstruation and 205 postmenopausal women were enrolled in this study. BMD at lumbar spine (L(2 - 4)) and femoral neck (FN) were measured with dual-energy X-ray absorptiometry (DEXA). Fat mass and fat-free mass were measured with bioelectric impedance analysis (BIA). Height, weight, waist and hip circumference were recorded. Body mass index (BMI) and waist hip ratio (WHR) were calculated.
Results: Fat mass and fat-free mass were significantly positively correlated with L(2 - 4) and FN BMD in both pre- and postmenopausal women (P < 0.01). Multiple regression analysis showed that in premenopausal women, fat-free mass and age were significant determinants of L(2 - 4) BMD (R(2) = 0.077, P = 0.000), while fat-free mass, age and BMI were significant determinants of FN BMD (R(2) = 0.130, P = 0.000). In postmenopausal women, fat mass and age were significant determinants of BMD at L(2 - 4) and FN (R(2) were 0.153 and 0.184 respectively, P = 0.000).
Conclusions: Fat mass and fat-free mass have different effects on BMD in pre- and postmenopausal women. Fat-free mass is a significant determinant of BMD in premenopausal women, while fat mass contributes most to BMD in postmenopausal women.

Introduction: For preterm infants, the first two weeks after birth are a time when nutrition and protein intake is variable and often falls below recommended intakes. Our objective was to investigate the relationship between protein intake, including source of protein, during the first two weeks after birth and fat-free mass (FFM) accretion in a group of very preterm infants.
Methods: In this observational cohort study, body composition was assessed using air displacement plethysmography in eligible infants <32 weeks gestational age at two weeks after birth and prior to discharge.

Background: Patients with liver cirrhosis are universally malnourished and the nocturnal snacks intervention is the currently recommended nutritional intervention for patients with liver cirrhosis. Body composition is an important indicator for the assessment of nutritional conditions. We investigated the effects of nocturnal snacks (200 kcal/day) for 3 months on body composition in patients with liver cirrhosis.

Background/aim: To elucidate the relationship between metabolic syndrome (Mets) and somatic composition [fat mass, fat-free (FF) mass, and fat to fat-free (F-FF) ratio] among health checkup recipients (7,776 males and 10,121 females).
Patients And Methods: We classified study subjects into four types considering Japanese criteria for Mets; Type A is for males with waist circumference (WC) <85 cm and females with WC <90 cm, Type B is for males with WC ≥85 cm and females with WC ≥90 cm, but without any metabolic abnormalities, Type C is for males with WC ≥85 cm and females with WC ≥90 cm and one metabolic disorder (pre-Mets), and Type D is Mets. We compared baseline characteristics among types of A, B, C, and D.

Introduction: This work aims at evaluating the adaptations of the energy cost of walking (Cw) to simulated weight gain at different walking speeds in adolescents with obesity.
Methods: Substrate use and Cw were evaluated during a graded walking exercise (4 × 5min at 0.75, 1, 1.

Associations of adiposity with risks of oesophageal squamous cell carcinoma (ESCC) and non-cardia stomach cancer, both prevalent in China, are still inconclusive. While adiposity is an established risk factor for colorectal cancer, the relevance of fat-free mass and early-adulthood adiposity remains to be explored. The prospective China Kadoorie Biobank study included 0.
