OBJECTIVES. This study undertook to examine relationships between nonsedentary activity level, time spent watching television (TV)/videocassette recorder (VCR), and risk of overweight among men. METHODS. Men participating in the Health Professionals Follow-Up Study were mailed surveys. Cross-sectional analyses examined the prevalence and odds of being overweight, prospective analyses determined cumulative incidence rates and relative risks of becoming overweight over 2 years of follow-up. RESULTS. Cross-sectionally, odds of being overweight were 50% (95% confidence interval [CI] = 45%; 55%) lower for men in the highest quintile of nonsedentary activity level when compared with men in the lowest quintile. Among men watching 41 or more hours of TV/VCR per week, the odds of being overweight were 406 (95% CI = 2.67, 6.17) times greater than those for men watching no more than 1 hour per week. Prospectively, higher levels is of nonsedentary activity and lower levels of TV/VCR viewing were independently associated with lower relative risks for becoming overweight between survey years. CONCLUSIONS. Both a lack of nonsedentary activity and time spent watching TV/VCR contribute to the development of overweight in men. Sedentary and nonsedentary activities represent separate domains, each with independent risks for overweight.

This case reinforces the need for strict screening of internationally transferred patients.

We examined the effect of television viewing on resting metabolic rate (RMR) in a cohort of 9 obese and 18 nonobese girls aged 10.4 +/- 1.1 y. RMR was measured while girls watched television, read, or sat quietly for 15 min. Movement was assessed by using activity monitors and a manual count of movements observed on a videotape. Absolute RMR was greater for the obese girls, but no significant treatment effect existed for absolute RMR within either group. Although measured activity did not differ, observed movements were greater when the girls were sitting quietly. Total observed and measured movements were significantly correlated with the CV of the minute-by-minute RMR. These results suggest that television viewing does not alter RMR. Although children appear to fidget more when sitting quietly than when they read or watch television, fidgeting appears to affect the minute-to-minute variation of RMR rather than the level of resting energy expenditure.

Nonobese, preadolescent girls self-reported, and their parents provided proxy reports of daughters’ daily activities using questionnaires. Responses were evaluated for test-retest reliability, and for validity using one-week diaries. Results indicated all three respondents provided reproducible estimates of time daughters spent watching TV; daughters and mothers, of time daughters spent sleeping; and parents, of time daughters spent in vigorous activities. However, only daughters >10 years of age could provide valid reports for time spent in moderate activities and in sedentary and light activities on school days. Study results suggest that daughters and parents have difficulty providing reliable and valid estimates of activity level.

Uptake of varicella vaccine has been steady and is an example of successful elimination of racial and ethnic disparities. Additional focus should be placed on reducing missed opportunities for simultaneous vaccination, improving coverage in rural areas and the Midwest region, and closing remaining gaps related to maternal education, provider type, and multiple-children households.
