Increased physical activity may be more protective for metabolic syndrome than reduced caloric intake. An analysis of estimated energy balance in U.S. adults: 2007-2010 NHANES.

BACKGROUND AND AIM: The purpose of this study was to examine the association between physical activity (PA), caloric intake, and Metabolic Syndrome (MetS) in a representative sample of the United States population. METHODS AND RESULTS: Data for 4327 adults from 2007 to 2010 NHANES were analyzed. MetS was defined using both ATPIII and AHA/NHLBI criteria. Weekly moderate and vigorous physical activity (PA) minutes from work, leisure-time, and transportation PA were used to estimate Total Energy Expenditure (TEE) from Basal Metabolic Rate (BMR) using the Harris-Benedict equation. Average total calories (KCAL) from two 24-h dietary recalls were used to compare energy intake and expenditure between subjects with and without MetS. An alpha of 0.05 was used to determine statistical differences. The age adjusted prevalence of MetS was 21.9% (95% CI 20.1-23.6) and 36.8% (34.7-39.0) using ATPIII and AHA/NHLBI criteria, respectively. The estimated population mean for KCAL/TEE was 0.83 (95% CI 0.82-0.84), and the mean for KCAL/BMR was 1.25 (95% CI 1.23-1.27). Subjects without MetS (MetS-) reported 36 ± 13 (ATPIII) and 45 ± 18 (AHA/NHLBI) more daily moderate PA minutes than subjects with MetS (MetS+). At each level of PA, MetS- consumed more calories relative to BMR and TEE than MetS+. For both normal and overweight adults, KCAL/BMR was higher for MetS- than MetS+. For all BMI groups, there were no differences between MetS- and MetS+ with respect to KCAL/TEE. Though MetS+ adults in either MetS criteria were generally less physically active, MetS- adults maintained a higher caloric intake relative to estimated energy needs. CONCLUSIONS: These results suggest energy needs may be distorted in Metabolic Syndrome and increased physical activity may be more protective than reduced caloric intake.

Evaluation of menus planned in Mississippi child-care centers participating in the Child and Adult Care Food Program.

OBJECTIVES: To collect information from licensed child-care centers in Mississippi on their foodservice operations relative to participation in the Child and Adult Care Food Program sponsored by the US Department of Agriculture (USDA); to collect information on who planned the menus; and to evaluate the energy and nutrient content of the planned menus relative to the suggested goal of one third of the Recommended Dietary Allowances (RDAs) and the recommendations made in the Dietary Guidelines for Americans. DESIGN: Survey questionnaire. SETTING: Licensed child-care centers in Mississippi. SAMPLES: Ninety-two licensed child-care centers provided cycle menus for analysis. One hundred eighteen centers returned the questionnaire. MAIN OUTCOME MEASURES: Content of the menus relative to the meal-pattern guidelines established for the Child and Adult Care Food Program; the energy and nutrient content of the menus relative to the RDAs and the Dietary Guidelines for Americans. STATISTICAL ANALYSES PERFORMED: One-way analysis of variance and frequencies. RESULTS: Seventy-five percent of the centers reported participating in the Child and Adult Care Food Program. All but one of the centers planned menus that met the meal-pattern requirements established by the program, licensure, and Head Start Performance Standards. Results showed that following the established meal-pattern guidelines for the child nutrition programs may not guarantee consistent nutritional quality of planned menus in child-care centers. The mean amounts of energy and many nutrients were significantly lower (P < .05) for centers that reported participating in the Child and Adult Care Food Program. Mean fat levels for all centers exceeded the recommendation of no more than 30% of total energy from fat: 40.8% of total energy from fat was reported by centers that participated in the program and 38% by those that said they did not. APPLICATIONS: Additional guidance is needed for menu planning in child-care centers to ensure compliance with the nutritional goal of meeting one third of the RDAs and Dietary Guidelines for Americans.
