Alanine transaminase individual variation is a better marker than socio-cultural factors for body mass increase in healthy males


Henneberg, M; Rühli, Frank J; Gruber, P; Woitek, U (2011). Alanine transaminase individual variation is a better marker than socio-cultural factors for body mass increase in healthy males. Food and Nutrition Sciences, 2(10):1054-1062.

Abstract

Overweight and obesity are considered a major burden on public health in developed countries. Underlying etiologies are enigmatic and metabolic causes have been suggested to various extents before. We analyze links of major blood parame-ters to individual body mass in a young male cohort, controlling for socio-cultural factors, in order to explore an underly-ing metabolic cause of obesity. Anthropometric (height, weight) physiologic (blood pressure) and metabolic data (total cholesterol, alanine transaminase, creatinine, postprandial glucose, blood cell counts, haemoglobin) of Swiss conscripts (N = 46,684; 18 - 20 yrs old; 2005-2007 census) were examined in the context of their socio-cultural groupings (occupa-tion, mother tongue, religion) by ANOVA and stepwise multiple regression analysis. Swiss Armed Forces recruiting is mandatory, thus each year’s group studied reflects more than 80% of a year’s male Swiss citizen birth cohort. Individual body mass index ranged from 19 kg/m2 (5th percentile) to 29 kg/m2 (95th percentile) with a median of 22 kg/m2. BMI in-creases significantly, even within its normal range (18.5 - 25 kg/m2) with increases in alanine transaminase (r2 = 0.10), total cholesterol (r2 = 0.08) and erythrocyte counts (r2 = 0.02). All other parameters, including socio-cultural categories, explain individually 1% or less of total BMI variation. Glucose values do not correlate with BMI significantly, thus sug-gesting a specific metabolic co-etiology of individual mass increases. There may occur a biochemical anomaly in liver metabolism that underlies development of the metabolic syndrome later in life. Were it so, pharmacological intervention rather than just diet and exercise regime could be more effective treatment of obesity.
