Promoting physical activity and a healthful diet among children: results of a school-based intervention study.
BACKGROUND: National health objectives call for improved diet and more regular physical activity among children. We tested the effects of a school-based program to improve students' diet and physical activity behavior at school. METHODS: Two of the four elementary schools in one Texas school district were assigned to intervention and two to control conditions. The three intervention components were classroom health education, vigorous physical education, and lower fat, lower sodium school lunches. Nutrients from school lunches and the total day and the amount of physical activity students obtained during physical education were assessed as outcome. RESULTS: Analysis of school lunches showed declines from base line to posttest in the two intervention schools of 15.5% and 10.4% for total fat, 31.7% and 18.8% for saturated fat, and 40.2% and 53.6% for sodium; posttest values were lower in the intervention schools. Observation of physical activity during physical education classes indicated an increase in the intervention schools from baseline to posttest in the percent of time children engaged in moderate-to-vigorous physical activity from less than 10% of class time at baseline to about 40% of class time at posttest; posttest values were higher in the intervention schools than in the control schools. CONCLUSIONS: This efficacy study demonstrates the feasibility of substantially modifying school lunches and school physical education to improve children's diet and physical activity behavior at school.

Children's frequency of participation in moderate to vigorous physical activities.
Third and fourth grade boys (n = 422) and girls (n = 390) in four Texas elementary schools reported their participation in moderate to vigorous physical activities (MVPAs) over a 3-day period. Students were surveyed during class on successive days. On a subsample (n = 44), the agreement between reported and observed physical activities during physical education or recess was 86.3%. Running, walking fast, games and sports, and bicycling accounted for 70% of Total MVPAs. Of Total MVPAs reported, 47.0% for boys and 44.6% for girls were 10 min or longer in duration (LMVPA). The average number of LMVPAs per day was 1.7 for both boys and girls. Students reported significantly more occurrences of LMVPAs out of school than during school. Significant interaction between grade and gender indicated that third grade boys reported more Total MVPAs and LMVPAs than third grade girls, but fourth grade boys reported fewer Total MVPAs and LMVPAs than fourth grade girls reported fewer Total MVPAs and LMVPAs than fourth grade girls. During the 3-day reporting period, 12.3% of boys and 13.3% of girls reported no LMVPAs, and 35.6% of boys and girls reported fewer than one LMVPAs per day. While the majority of children reported obtaining at least some activity daily, a substantial proportion of children in this sample reported fewer than one LMVPA daily, indicating that many children may not be obtaining adequate amounts of physical activity.

Validity of the observation of children's physical activity.
An observational method for quantifying intensity of activity was validated against min-by-min heart rates during physical education periods. The mean heart rate values increased as the activity points increased. Moderate average correlations were obtained between the min-by-min activity points and heart rates. A time series regression analysis accounted for 72% of the variance in heart rate values with a model combining heart rate in the previous min and activity points. Further work on estimates of average metabolic units for activity categories will enable future investigators to obtain more precise estimates of energy expenditure from this observation system.

A hospital-based infant safety seat program for low-income families: assessment of population needs and provider practices.
Evaluation of a hospital-based car safety seat education and loan program for low-income families included hospital interviews with new mothers (N = 94), a survey of pediatricians (N = 28), and a task analysis of the program coordinator's time. Mothers who entered the hospital with safety seats were more likely than those without safety seats to (1) be White or Mexican-American than Black; (2) not be dependent on public transportation; (3) have an older child who always rides in a car seat; and (4) wear seat belts themselves. Mothers with seats did not differ from mothers without seats in knowledge or beliefs about the importance of, or intent to use, car seats. Of mothers without seats, 86.3% were aware of the hospital's car seat rental program, but only 12 of 51 rented a seat from the program. 61% of pediatricians surveyed believed that mothers' lack knowledge and skills to acquire and use car seats regularly, but only 31% always included education about the importance of using car seats and only 21% always referred mothers without seats to the rental program. Car seat loan programs addressing low-income populations should place greater emphasis on education of medical providers to provide education and referrals, encourage organizational policy that requires a safe first ride home and address issues of social support and perceived norms and ease of acquisition.

An ecological approach to the prevention of injuries due to drinking and driving.
Among the many alcohol-related public health concerns, motor vehicle crashes account for nearly one-third of all deaths attributable to alcohol. Adolescents and young adults, particularly males, are important target populations for intervention efforts. Taking an ecological perspective of individuals within their social and physical environments, a diagnostic framework is employed in reviewing the literature on factors associated with drinking and driving injuries and on interventions to prevent injuries due to drinking and driving. Intervention planning is conceptualized according to a multilevel intervention framework, which consists of four phases: (1) health goals selection, (2) intervention planning, (3) intervention, and (4) evaluation. Possible intervention objectives, targets of the intervention actions, intervention approaches, and evaluation criteria are identified and discussed for three societal levels and four practice settings.

Prescribing physical activity to prevent disease.
Despite an increase in the public's awareness of the ample health benefits of physical activity, less than 20% of US adults regularly participate in moderate to vigorous physical activity. For most adults, increasing physical activity even moderately is likely to benefit health. Physicians can prescribe physical activity and incorporate an emphasis on physical activity into clinical practice.

Implementing organizational changes to promote healthful diet and physical activity at school.
Diet and physical activity patterns appear to be learned at early ages, suggesting the need for school-based intervention. The potential of schools to improve children's diet and physical activity has been offset by countervailing school environments. In the first year of the "Go For Health" health promotion project, organizational change innovations were implemented to facilitate changes in school lunch, physical education, and classroom health education in support of healthful student diet and physical activity. At first follow-up after one year of intervention, the amount of sodium in selected foods served in school lunch was reduced from baseline (1985) to year one (1986) in the experimental schools by 29 and 33%, respectively, and fat was reduced by 28 and 42%, respectively. At first follow-up, students in the experimental schools participated in fitness activities 44.1 and 38.0% of the time, compared with 19.5 and 22.7% in the control schools.

Health promotion: integrating organizational change and student learning strategies.
The background and conceptual support for a model for planned change in schools are presented to facilitate the adoption, implementation, and maintenance of health promotion innovations. The model proposes four phases of change: (1) institutional commitment, (2) alterations in policies and practices, (3) alterations in roles and actions of staff, and (4) student learning activities. The model can be applied to influence organizational change in multiple components of the school health program to predispose, enable, and reinforce student health behavior.

Health promotion and disease prevention. Roles for the primary care physician.
The practice of health promotion and disease prevention (HPDP), an increasingly important approach to healthcare, includes influencing health behaviors of the population at risk for disease as well as environmental conditions that affect health. The major role of the clinician in HPDP is at the individual level: screening for risk factors and disease and providing early treatment, advice, counseling, and referral. Primary care physicians can broaden their impact by assuming roles at organizational, community, and government levels (eg, as an active member of an organization or a consultant to an outside organization, a community leader or an agent of change, an influential constituent or a lobbyist). These roles enable primary care physicians to have an impact both on individuals and on environments to reduce disease risk factors.

School promotion of healthful diet and exercise behavior: an integration of organizational change and social learning theory interventions.
In the Go For Health project, interventions based on organizational change and social learning theory facilitate changes in diet and exercise behavior by elementary school children. Baseline data documented the need for behavior change. Based on chemical analyses, average per meal amounts of total fat and sodium were higher than national recommendations: total fat was 29.3% higher than U.S. Dietary Goals; sodium was 107.4% greater than recommended levels. Observations of students in physical education class revealed children moved through space 50.1% of the time and moved continuously an average of 2.2 minutes per class period. These findings suggest the need for policy and practice changes in the school environment to enable children to engage in more healthful diet and exercise behavior.

Effectiveness and cost effectiveness of persuasive communications and incentives in increasing safety belt use.
The Safety Belt Connection Project was a worksite health promotion project conducted at a medical school and hospital complex to test the effectiveness and cost effectiveness of four treatment conditions (TCs): TC1, Persuasive Communications (PCs) alone; TC2, PCs plus overt monitoring; TC3, PCs plus incentives; and TC4, PCs plus incentives and prompts. Parking lots were randomized to treatment condition. A community traffic intersection served as a comparison group. Trained observers recorded safety belt use rates (SBURs) of subjects (front seat occupants) over a two-week period at baseline and after a four-week period of intervention. Results were analyzed by chi-square comparisons of pre-treatment and post-treatment SBURs. At baseline, significant differences in SBURs between treatment groups were observed. Significant pre-to-post differences were found for TC3 and TC4: the SBUR in TC3 went from 18.3% - 38.4% (p less than 0.001) and the SBUR in TC4 went from 16.9% - 44.8% (p less than 0.001). Both TC3 and TC4 were effective, but TC4 cost 2.6 times more per person influenced to wear their safety belt.

Great Sensations: a program to encourage heart healthy snacking by high school students.
The Great Sensations program consisted of three interrelated educational strategies--classroom instruction, parent outreach, and media campaign. These strategies were designed to teach inner-city high school students about salt and high blood pressure, and to encourage them to eat more low-salt snacks and fewer high-salt snacks. Eight classes at the experimental school were randomly assigned to class instruction or parent outreach in a factoral design. All students in the experimental school were exposed to the media campaign. Students at a nearby high school served as the comparison group. All but a few of the 490 students at the two schools were black. Students who received the classroom instruction reported lower Salty Snack selection and higher Target Snack selection at posttest and eight-week follow-up. Students receiving media only reported lower Salty Snack selection at posttest but this condition returned to baseline by eight weeks. The control group reported little change in snack selection at posttest and eight weeks. After six months, program effects were no longer evident for either experimental group.

Strategies to improve patient compliance with antihypertensive therapy.
Compliance is a critical issue in the treatment of hypertension. Strategies designed for individual patients, based on an analysis of their specific personality characteristics, are probably the most productive. At present, however, necessary educational diagnoses cannot easily be made. Therefore, more general strategies involving simplification of the treatment regimen, stimuli to appropriate behavior, positive reinforcement, increased attention by providers, and open communications should be employed. These are of particular value for patients with inadequately controlled blood pressure who admit to noncompliance.

Prevalence and predictors of the prone sleep position among inner-city infants.
CONTEXT: The prone sleep position is associated with an increased risk of sudden infant death syndrome (SIDS), but few studies have assessed factors associated with the choice of infant sleep position. OBJECTIVES: To describe infant sleep position in a cohort of infants born to predominantly low-income, inner-city mothers and to identify predictors of the prone sleep position in this population. DESIGN: Prospective birth cohort study. PATIENTS AND SETTING: Three hundred ninety-four mother-infant dyads, systematically selected from 3 District of Columbia hospitals between August 1995 and September 1996. Mothers were interviewed shortly after delivery and again at 3 to 7 months postpartum. MAIN OUTCOME MEASURES: Position in which infants were placed for sleep on the night prior to the 3- to 7-month interview. RESULTS: At 3 to 7 months of age, 157 infants (40%) were placed for sleep in the prone position. Independent predictors of prone sleep position included poverty (odds ratio [OR], 1.81; 95% confidence interval [CI], 1.10-2.99), black race (OR, 2.06; 95% CI, 1.05-4.04), presence of infant's grandmother in the home (OR, 1.83; 95% CI, 1.11-3.00), and intent, as measured shortly after delivery, to place the infant in the prone position (OR, 2.28; 95% CI, 1.44-3.60). Importantly, of the 43 mothers who observed their infants in the prone sleep position while in the hospital, 40 (93%) intended to place their infants prone at home. CONCLUSIONS: A substantial proportion of infants in this predominantly low-income population were placed in the prone sleep position. Educational efforts should address both initial intentions and reinforcement of the correct sleep position, once initiated. Hospitals should ensure that healthy newborn infants are placed in the supine sleep position during the postpartum hospital stay.
