- Principally to ascertain whether mineral metabolism is involved in weight regulation, the 40 most obese of 1,774 children, aged 10-11 years, screened for obesity were compared with 46 age-matched controls. The obese children had more 3H-Ouabain erythrocyte binding sites (p = 0.04), higher intracellular sodium (p = 0.04), and lower plasma sodium (p = 0.002). After exclusion of the non-Scandinavians, the p values were p = 0.02, p = 0.03, and p = 0.03, respectively. Analysis of variance also showed the differences to be more dependent on obesity than on gender or nationality. It is concluded that obese children have more 3H-Ouabain erythrocyte binding sites indicating an increase of the sodium-potassium adenosine triphosphatase activity. The increase of intracellular sodium may increase the risk of future hypertension.

- Body mass index (BMI), the distribution of fat, birth weight, physical fitness, apolipoproteins (apo) A-I and B, total cholesterol (TC), and high-density lipoprotein cholesterol (HDLC) were studied in 38 obese 10- to 11-year-olds in comparison to 52 age-matched controls. Obese children had higher concentration of apo B and a lower apo A-I:B ratio. Significant correlations were found between (a) apo A-I and physical fitness (r = 0.35, p less than 0.015), triceps skinfold thickness (r = 0.44, p less than 0.01), and birth weight (r = -0.33, p less than 0.05); (b) physical fitness and triceps skinfold thickness (r = 0.38, p less than 0.05), and (c) the apo A-I:B ratio and triceps skinfold thickness (r = 0.31, p less than 0.05). When both obese and control children were grouped together, a correlation was found between BMI and TC (r = 0.24, p less than 0.05), apo B (r = 0.37, p less than 0.001), and the apo A-I:B ratio (r = -0.31, p less than 0.01). Multiple regression analyses indicated a significant positive contribution to the apo A-I level by HDLC and physical fitness and a negative one by birth weight.
