Association of Dietary Calcium Intake and Body Fat with Hypertension in Indian Adolescents.

To explore association of dietary-calcium intake and body-composition with blood-pressure, 417 apparently healthy adolescents (218 boys) were studied for anthropometry, blood pressure, body composition and nutrient intakes using standard protocols. Blood pressure correlated negatively with dietary calcium (r= -0.120, P<0.01) and positively with body fat (r=0.56,P<0.001). Low dietary-calcium intakes and high adiposity may increase risk of hypertension in Indian adolescents.

Growth of Short Children Born Small for Gestational Age and Their Response to Growth Hormone Therapy.

Growth hormone [GH] is licensed for use in children born small for gestational age (SGA) who fail to catch-up. We retrospectively compared the response of twenty children born SGA (who satisfied the auxological criteria) to growth hormone (Group I) versus randomly selected age and sex matched controls from a group of SGA children with growth related complaints, not treated with GH (Group II). After 2 years of GH therapy the HAZ increased from -2.8 to -1.6 in Group I, compared 2.2 to -1.7 in group II (P-value < 0.05). The percentage of pubertal children rose from 55% to 65% in cases versus 60% to 75% in the controls (P>0.05). GH resulted in increase in growth velocity Z-score during the first year and (4.3±0.5 in Group-I versus - 0.5±0.6 in Group-II, P<0.05) second year of treatment (1.7±0.4 in cases versus -0.6±0.7 in controls, P<0.05).Thus, GH improves height of short SGA children without accelerating pubertal progression.
