Current Trends in Food Habits and Dietary Intakes of Home Economics Students in Three Junior High Schools in Rhode Island

Abstract: Ten-day dietary records of 205 female and 73 male home economics students, 13 and 14 years of age, indicated that the males had a significantly higher intake of all nutrients except ascorbic acid. Snacks contributed more to the total daily intake of females than to that of males, and break fast contributed less than one-quarter of the daily intake for a majority of the nutrients. The average intake of iron was low for both sexes. At the lower limits of adequacy (approximately 67 per cent of the 1974 RDA) were the average intakes of calcium and energy for the females, while the remain der of the nutrients were adequate for both males and females.

Dietary patterns with special reference to calcium intake in 2-16-year-old Urban Western Indian children.

Abstract: Background: It is important to establish good dietary practices in childhood that promote adequate calcium intake throughout life and reduce the risk of osteoporotic fractures in later life. Objectives: To assess dietary patterns of 2–16-year-old children with special reference to calcium and suggest strategies and develop recipes suitable to identified patterns to increase dietary calcium intake. Methods: We studied 220 schoolchildren (2–16 years) around Pune city, India. The study duration was June 2013–July 2014. Height and weight were measured using standard protocols. Dietary intake was assessed by 24-h diet recall on 3 nonconsecutive days. Dietary patterns were derived by cluster analysis in two age groups; children (2–9 years) and adolescents (10–16 years). As per the dietary patterns, calcium-rich recipes were developed. Results: Among children, “rice-pulse” (RP) and “wheat, milk, and milk products” (WM) patterns were observed. Among adolescents, RP, “wheat, milk, and bakery” (WMB), and “mixed food” patterns were observed. Children who consumed “WM” and “WMB” patterns had greater intake of calcium (P < 0.05) than children consuming other dietary patterns. The daily calcium intake of whole group was 53% of the recommended dietary allowance. From this, 30% calcium came from milk. Each serve of the developed recipe provided an average of 254 mg of calcium. Conclusion: Majority of children had cereal-pulse-based dietary patterns. By replacing foods from existing dietary patterns with calcium-rich foods, the dietary calcium content may be increased in a sustainable manner.

Dietary protein intake and upper leg muscle strength in subjects with knee osteoarthritis: data from the osteoarthritis initiative

Abstract: The aims of this study were (1) to describe dietary protein intake, and (2) to evaluate the association between dietary protein intake and upper leg muscle strength in subjects with knee osteoarthritis (OA). Baseline data from the OA was used, in a cross-sectional study. All subjects were diagnosed with symptomatic and radiographic knee OA. Daily dietary protein intake was measured with the Block Brief 2000 food frequency questionnaire (g/kg body weight). The sum of knee flexion and extension strength of the index knee (N/kg bodyweight) was assessed with the Good Strength chair test. Linear regression analysis was used to test the association between dietary protein intake and muscle strength, adjusting for relevant confounders. Data from 1316 subjects (mean age 61.4 ± SD 9.1 years, 57.0% female) were used. The mean daily protein intake was 0.72 ± SD 0.30 g/kg bodyweight, and 65.1% of the subjects had a protein intake lower than the recommended daily allowance of 0.8 g/kg bodyweight. The mean muscle strength was 5.4 ± SD 2.1 N/kg bodyweight. Lower protein intake was significantly associated with lower muscle strength (B = 0.583, 95% CI 0.230–0.936, p = 0.001). The majority of the subjects with knee OA had a dietary protein intake lower than the recommended daily allowance. Lower protein intake was associated with lower upper leg muscle strength. Longitudinal observational and interventional studies are needed to establish whether dietary protein intake has a causal effect on muscle strength in subjects with knee OA.
