RESUMEN
BACKGROUND: Growth trajectories have shown to be related to obesity and metabolic risks in later life, however body mass index (BMI) trajectories according to the presence or absence of metabolic syndrome (MS) and its parameters in adulthood are scarce in literature. OBJECTIVES: To investigate BMI trajectories during childhood in relation to MS and its parameters in adult age. METHODS: A total of 1919 subjects (43.4% male, 20-60 y) participated in this retrospective cohort study. Height, weight, waist circumference (WC), blood glucose, high-density lipoprotein cholesterol, triglycerides and blood pressure were measured at adulthood. Childhood weight and height were collected retrospectively from health booklets. Differences between BMI growth curves of subjects with and without MS were assessed using mixed models for correlated data. RESULTS: BMI trajectories differed according to the presence or not of MS at adulthood, from the age of 4 years forward (all P<0.05), to the presence or not of hypertriglyceridemia from 1.5 years forward (all P<0.05), and to WC>94 cm (men) / 80 cm (women) compared to lower WC, at all ages (all P<0.05). CONCLUSIONS: BMI growth curves differ according to the presence or not of MS at adulthood, but differences only appeared after the age of 4 years. Changes vary according to the MS parameters considered. Deviation of the MS-associated BMI curve from normal pattern could correspond to alteration in body composition. These differences in BMI trajectories during childhood support the theory of an early origin of the MS, justifying early prevention.

OBJECTIVE: Early-life growth characteristics and in particular age at adiposity rebound (AR), have been shown to impact nutritional status later in life but studies investigating the association with long-term health remain scarce. Our aims were to identify determinants of age at AR and its relationship with nutritional status and cardiometabolic risk factors at adulthood. DESIGN: A total of 1465 subjects aged 20-60 years participated in this retrospective cohort study. Height, weight, waist circumference, blood glucose, lipids and blood pressure were measured at adulthood. Childhood weight, height, gestational age, birth weight and early nutrition were collected retrospectively from health booklets and age at AR was assessed. Participants self-reported parental silhouettes. Associations were assessed using multiple linear and logistic regression. RESULTS: An earlier AR was associated with higher body mass index and waist circumference at adulthood in both men and women (P<0.0001). In addition, women with an earlier occurrence of AR had higher triglyceride (P=0.001), low-density lipoprotein-cholesterol (P=0.001), systolic (P=0.02) and diastolic blood pressure (P=0.04) at adulthood. Both men (odds ratio (OR) (95% confidence interval (CI)): 0.82 (0.70-0.95)) and women (OR (95% CI): 0.84 (0.73-0.96) with an AR occurring earlier were more likely to develop a metabolic syndrome. Larger parental silhouette was associated with an earlier AR. CONCLUSIONS: This long-term study showed that age at AR was associated with nutritional status and metabolic syndrome at adulthood. These results highlight the importance of monitoring childhood growth so as to help identify children at risk of developing an adverse cardiometabolic profile in adulthood. AR determinants for use in overweight surveillance were identified.

INTRODUCTION: A muscle mass normalized for height2 (MMI) or for body weight (SMI) below 2SD under the mean for a young population defines sarcopenia. This study aimed at setting the cutoffs and the prevalence of sarcopenia in the French elderly population. Another objective was to compare the results obtained with SMI and MMI. METHODS: Muscle mass was assessed by bioelectrical impedance analysis in 782 healthy adults (< 40 years) to determine skeletal mass index (SMI, muscle mass*100/weight) and muscle mass index (MMI, muscle mass/height2). Prevalence was estimated in 888 middle aged (40-59 years) and 218 seniors (60-78 years). All were healthy people. RESULTS: For women mean-2SD were 6.2 kg/m2 (MMI) and 26.6% (SMI); for men limits were 8.6 kg/m2 (MMI) and 34.4% (SMI). In middle aged persons a small number of them were identified as sarcopenic. In healthy seniors, 2.8% of women and 3.6% of men were sarcopenic (MMI). The prevalence was 23.6% in women and 12.5% in men with SMI. MMI and SMI identified different sarcopenic populations, leaner subjects for MMI while fatter subjects for SMI. CONCLUSION: Cutoff values for the French population were defined. Prevalence of sarcopenia was different from that in the US population.
