These results suggest that saturated FA intake may significantly increase hip fracture risk, whereas monounsaturated and polyunsaturated FA intakes may decrease total fracture risk. In postmenopausal women with a low intake of marine n-3 FAs, a higher intake of n-6 FAs may modestly decrease total fracture risk. This trial was registered at clinicaltrials.gov as NCT00000611.

A dietary study of 10-year-old children was incorporated into a larger epidemiological survey investigating the distributions, interrelationships, and course-over-time of arteriosclerosis risk factor variables in children. Food intakes, eating patterns, and diet-risk factor interrelationships are described for 185 children (35% black, 65% white) using an improved 24-hr dietary recall method. Protein intakes were high. The polyunsaturated-to-saturated fatty acid ratio averaged 0.4 and a sucrose-to-starch proportion of 1.1 was noted. Eggs were the main food source of cholesterol and milk was the prime source of saturated fatty acids and protein. Black girls had a significantly greater mean sodium intake than the three other sex-race groups. Intermittent snacks provided the most calories; breakfast and dinner contributed most of the day's cholesterol, and lunch was the prime source of lactose and calcium. Longer eating spans reflected significantly greater intakes of calories, protein, fat, carbohydrate, and sodium, and greater levels of total serum cholesterol. A lack of correlations was noted in large matrices of dietary components and risk factor variables, but results of the comparison of mean intakes of dietary components for children grouped according to serum cholesterol showed significant differences in the intakes of various forms of fat and carbohydrate.

Relationships between diet and cardiovascular disease risk factors were studied in a cohort of infants in Bogalusa, Louisiana. The 24-hour dietary recalls and cardiovascular measurements were obtained on each child at age 6 months, yearly through age 4, and again at age 7 (cardiovascular measurements only). At ages 4 and 7, children with persistently high intakes of dietary cholesterol (three or more measurements in the upper tertile) had levels of serum total cholesterol approximately 14 mg/dl higher than children whose intakes of cholesterol were not persistently high. Children in the upper tertile for dietary cholesterol had levels of low density lipoprotein cholesterol (15 mg/dl at age 4 and 18 mg/dl at age 7) higher than children in the lower tertile for dietary cholesterol. Children with high intakes of animal fat were 2 to 6 kg heavier (p less than 0.05) than those with lower intakes. Changes in dietary cholesterol correlated significantly with changes in serum total cholesterol (r = 0.42) and low density lipoprotein cholesterol (r = 0.50) from 6 months to 4 years of age. Changes in subscapular skinfold measurements correlated significantly with changes in intake of total protein (r = 0.31), total fat (r = 0.25), starch (r = 0.31), and energy (r = 0.39) from ages 6 months to 4 years. Results indicate that tracking of dietary components and their relationships with cardiovascular disease risk factors can be detected at an early age. These findings may well be the groundwork for later studies of obesity and the early onset of hyperlipoproteinemia.
