[Nutritional studies in a commune of Lazio. Anthropometric data and food consumption in childhood]

Abstract

The present study concerns with anthropometric and nutritional data collected in the school population of a small rural town in Lazio. We studied 368 school-children of both sexes, belonging to the following age groups: from 7 to 8 years, 9 to 10 years, 11 to 12 years, 13 to 14 years. The technique of evaluation of obesity used in this paper is: weight 20% higher than the height-adjusted figure according to NCHS's curves and triceps skinfold higher than 90 degrees centile according to Tanner's curves. Dietary intake was assessed by a "24 hour-recall" on three consecutive days one of which of holiday. The prevalence of obesity is 17.7%. In all the age groups daily caloric intake is adjusted to that recommended by Italian 1987 Larn. On the other hand the single nutrient's assumption shows important differences from Larn. Particularly in all the age groups daily protein intake is high (14.6%-15.8% of the energy in a day), with an increased animal-vegetable protein ratio (1.5-2.1). Dietary lipids are higher than 35.9% of day's energy (35.9%-39.5%); the polyunsaturated/saturated fatty acids ratio is low (0.3-0.5). Cholesterol in the diet (231-347 mg/day) exceeds the level recommended. The daily intake of total carbohydrates (45.3%-48.5%) is low. Crude fiber intake increases with age from 2.8 g to 4.5 g/day. There is no statistical difference between obese and not obese subjects for what concerns energy intake or single nutrient's assumption.(ABSTRACT TRUNCATED AT 250 WORDS)
