Development of a tool to measure the number of foods and beverages consumed by children using National Health and Nutrition Examination Survey (NHANES) FFQ data.

OBJECTIVE: There is currently no standard, objective definition of selective eating. This is partially because normative values for the number of different foods eaten by US children have not been established. The present study objectives were to: (i) perform exploratory analysis on the number of different foods, beverages, and total foods and beverages consumed by US children aged 2-18 years over a year's time, and the types of foods consumed by those in the lowest 2·5th percentile; and (ii) determine whether those values differ according to demographic variables and weight status. DESIGN: Secondary analysis of cross-sectional FFQ data. Differences in number of foods, beverages, and total foods and beverages were analysed using one-way ANOVA. SETTING: National Health and Nutrition Examination Survey (NHANES) for the years 2003-2006. SUBJECTS: Non-institutionalized US children aged 2-18 years. RESULTS: The mean number of different foods and beverages consumed across the sample was 83·2. There were no significant differences by gender, BMI, race or food security categories. There was a difference in beverage consumption by age category, with children aged 12-18 years consuming a significantly higher number of different beverages compared with each of the other two age categories (i.e. 2-5 years and 6-11 years). CONCLUSIONS: Normative values for the number of foods and drinks reported as consumed by children over the past 12 months may be a useful measure for researchers. Future research validating this measure is needed before cut-off values can be used to develop a definition of selective eating.

Musculoskeletal Discomfort, Physical Demand, and Caregiving Activities in Informal Caregivers.

OBJECTIVES: To characterize the burden of care and musculoskeletal discomfort associated with caring for adults with chronic physical disability among informal caregivers and to describe the most physically demanding caregiving activities and contributing factors, as perceived by informal caregivers of adults with physical disabilities. METHODS: A mixed methods approach was used for the study. Forty-six informal caregivers of adults with physical disability participated. RESULTS: Most caregivers were classified as "high burden" caregivers. They reported high levels of physical strain and musculoskeletal discomfort. Caregivers identified several activities related to mobility and self-care as the most physically demanding. Factors affecting physical demand included caregiver and care-recipient characteristics, activity requirements, and the physical environment. CONCLUSION: Interventions that target high-demand caregiving activities, including all three aspects of caregiving activity performance, are necessary to support adults with disabilities in the home and their caregivers.
