Background/Aims: Girls with low-birth weight (LBW) and postnatal weight catch-up tend to develop visceral and hepatic fat excess, which may be accompanied by an upregulated adrenarche with precocious pubarche (PP) and by a rapidly progressive puberty with early menarche and shorter stature. A pilot study suggested that metformin treatment for 4 years reduces central adiposity in LBW-PP girls and normalizes puberty and adult height. In this cohort, we studied the relationship between metformin treatment, bone maturation, and body composition. Methods: Longitudinal hand X-rays (0–4 years, analyzed by BoneXpert) were available from 34 LBW-PP girls (89% of the original cohort; n = 17 untreated, n = 17 metformin-treated; age at the start of treatment 8 years) along with body composition (0–4 years, by DXA), hepatic fat, and abdominally subcutaneous and visceral fat (posttreatment, by MRI). Results: The tempo of bone aging was accelerated in untreated girls (≈16% faster vs. chronological aging) and normal in metformin-treated girls (≈20% slower vs. untreated girls). Metformin-treated girls gained more height per bone-age year and had less visceral and hepatic fat. The tempo of bone maturation was associated (R = 0.55; p < 0.001) with hepatic fat. Conclusion: Metformin treatment in rapidly maturing girls with central adiposity normalized bone maturation. This normalization was accompanied by less central fat and was related closely to hepatic fat.

Abstract. Branched chain amino acids (BCAA), with vitamin B6 have been reported to improve fat metabolism and muscle synthesis. We hypothesized that supplementation with BCAA and vitamin B6 would result in more weight loss and improve body composition and blood markers related to cardiovascular diseases. Our aim was to determine whether the mentioned supplementation would affect weight loss, body composition, and cardiovascular risk factors during weight loss intervention. To this end, we performed a placebo-controlled randomized clinical trial in 42 overweight and obese women (BMI = 25–34.9 kg/m2). Taking a four-week moderate deficit calorie diet (–500 kcal/day), participants were randomized to receive BCAA (6 g/day) with vitamin B6 (40 mg/day) or placebo. Body composition variables measured with the use of bioelectrical impedance analysis, homeostatic model assessment, and plasma insulin, Low density lipoprotein, High density lipoprotein, Total Cholesterol, Triglyceride, and fasting blood sugar were measured. The result indicated that, weight loss was not significantly affected by BCAA and vitamin B6 supplementation (–2.43 ± 1.02 kg) or placebo (–1.64 ± 1.48 kg). However, significant time × treatment interactions in waist to hip ratio (P = 0.005), left leg lean (P = 0.004) and right leg lean (P = 0.023) were observed. Overall, supplementation with BCAA and vitamin B6 could preserve legs lean and also attenuated waist to hip ratio.
