    ABSTRACT: Electronically delivered health promotion programs that are aimed primarily at educated, health-literate individuals have proliferated, raising concerns that such trends could exacerbate health disparities in the United States and elsewhere. The efficacy of a culturally and linguistically adapted virtual advisor that provides tailored physical activity advice and support was tested in low-income older adults. Forty inactive adults (92.5% Latino) 55 years of age and older were randomized to a 4-month virtual advisor walking intervention or a waitlist control. Four-month increases in reported minutes of walking/week were greater in the virtual advisor arm (mean increase = 253.5 ± 248.7 minutes/week) relative to the control (mean increase = 26.8 ± 67.0 minutes/week; p = .0008). Walking increases in the virtual advisor arm were substantiated via objectively measured daily steps (slope analysis p = .002). All but one intervention participant continued some interaction with the virtual advisor in the 20-week poststudy period (mean number of poststudy sessions = 14.0 ± 20.5). The results indicate that a virtual advisor delivering culturally and linguistically adapted physical activity advice led to meaningful 4-month increases in walking relative to control among underserved older adults. This interactive technology, which requires minimal language and computer literacy, may help reduce health disparities by ensuring that all groups benefit from e-health opportunities.

    ABSTRACT: Older adults have low rates of physical activity participation, but respond positively to telephone-mediated support programs. Programs are often limited by reliance on professional staff. This study tested telephone-based physical activity advice delivered by professional staff versus trained volunteer peer mentors. A 12-month, randomized, controlled clinical trial was executed from 2003-2008. Twelve volunteer peer mentors and 181 initially inactive adults ages 50 years and older were recruited from the San Francisco Bay Area. Participants were randomized to: (1) telephone-based physical activity advice delivered by professional staff, (2) telephone-based physical activity advice delivered by trained volunteer peers, or (3) an attention-control arm of staff-delivered telephone support for nutrition. Moderate-intensity or more vigorous physical activity (MVPA) was assessed at baseline, 6, and 12 months with the Community Healthy Activities Model Program for Seniors (CHAMPS) Questionnaire, with accelerometry validation (Actigraph) in a randomly selected subsample. Treatment fidelity was examined through analysis of quantity and quality of intervention delivery. At 6 and 12 months, both physical activity arms significantly increased MVPA relative to the control arm. Both physical activity arms were comparable in quantity of intervention delivery, but peers demonstrated more versatility and comprehensiveness in quality of intervention content. This study demonstrates that trained peer volunteers can effectively promote physical activity increases through telephone-based advice. The results support a program delivery model with good dissemination potential for a variety of community settings.

    ABSTRACT: The extent to which light-intensity physical activity contributes to health in older adults is not well known. The authors examined associations between physical activity across the intensity spectrum (sedentary to vigorous) and health and well-being variables in older adults. Two 7-day assessments of accelerometry from 2005 to 2007 were collected 6 months apart in the observational Senior Neighborhood Quality of Life Study of adults aged >65 years in Baltimore, Maryland, and Seattle, Washington. Self-reported health and psychosocial variables (e.g., lower-extremity function, body weight, rated stress) were also collected. Physical activity based on existing accelerometer thresholds for moderate/vigorous, high-light, low-light, and sedentary categories were examined as correlates of physical health and psychosocial well-being in mixed-effects regression models. Participants (N = 862) were 75.4 (standard deviation, 6.8) years of age, 56% female, 71% white, and 58% overweight/obese. After adjustment for study covariates and time spent in moderate/vigorous physical activity and sedentary behavior, low-light and high-light physical activity were positively related to physical health (all P < 0.0001) and well-being (all P < 0.001). Additionally, replacing 30 minutes/day of sedentary time with equal amounts of low-light or high-light physical activity was associated with better physical health (all P < 0.0001). Objectively measured light-intensity physical activity is associated with physical health and well-being variables in older adults.

    ABSTRACT: Cognitive impairment is an important contributor to disability. Limited clinical trial evidence exists regarding the impact of physical exercise on cognitive function (CF). We report results of a pilot study to provide estimates of the relative impact of physical activity (PA) on 1-year changes in cognitive outcomes and to characterize relationships between changes in mobility disability and changes in cognition in older adults at increased risk for disability. Sedentary persons (102) at increased risk for disability (aged 70-89 years) were randomized to moderate-intensity PA or health education. Participants were administered the Digit Symbol Substitution Test (DSST), Rey Auditory Verbal Learning Test (RAVLT), modified Stroop test, and Modified Mini-Mental State Examination at baseline and 1 year. Group differences were not significant but improvements in cognitive scores were associated with improvements in physical function. Specifically, the DSST significantly correlated with change in the Short Physical Performance Battery score (r = .38, p = .0002), in chair stand score (r = .26, p = .012), in balance score (r = .21, p = .046), and in 400-m gait speed (r = .15, p = .147). Change recall on the RAVLT and in the Stroop test was also positively correlated with changes in chair stand and balance, respectively. These results provide further support for the benefits of exercise on CF in older adults. An adequately powered clinical trial of PA involving older adults at increased risk for cognitive disability is needed to expand the indications for prescribing exercise for prevention of decline in brain function.

    ABSTRACT: The authors explored using the ActiGraph accelerometer to differentiate activity levels between participants in a physical activity (PA, n = 54) or "successful aging" (SA) program (n = 52). The relationship between a PA questionnaire for older adults (CHAMPS) and accelerometry variables was also determined. Individualized accelerometry-count thresholds (ThreshIND) measured during a 400-m walk were used to identify "meaningful activity." Participants then wore the ActiGraph for 7 days. Results indicated more activity bouts/day > or =10 min above ThreshIND in the PA group than in the SA group (1.1 +/- 2.0 vs 0.5 +/- 0.8, p = .05) and more activity counts/day above ThreshIND for the PA group (28,101 +/- 27,521) than for the SA group (17,234 +/- 15,620, p = .02). Correlations between activity counts/hr and CHAMPS ranged from .27 to .42, p < .01. The ActiGraph and ThreshIND might be useful for differentiating PA levels in older adults at risk for mobility disability.

    ABSTRACT: This study sought to determine the 12-month effects of exercise increases on objective and subjective sleep quality in initially inactive older persons with mild to moderate sleep complaints. A nonclinical sample of underactive adults 55 years old or older (n=66) with mild to moderate chronic sleep complaints were randomly assigned to a 12-month program of primarily moderate-intensity endurance exercise (n=36) or a health education control program (n=30). The main outcome measure was polysomnographic sleep recordings, with additional measures of subjective sleep quality, physical activity, and physical fitness. Directional hypotheses were tested. Using intent-to-treat methods, at 12 months exercisers, relative to controls, spent significantly less time in polysomnographically measured Stage 1 sleep (between-arm difference=2.3, 95% confidence interval [CI], 0.7-4.0; p=003), spent more time in Stage 2 sleep (between-arm difference=3.2, 95% CI, 0.6-5.7; p=.04), and had fewer awakenings during the first third of the sleep period (between-arm difference=1.0, 95% CI, 0.39-1.55; p=.03). Exercisers also reported greater 12-month improvements relative to controls in Pittsburgh Sleep Quality Index (PSQI) sleep disturbance subscale score (p=.009), sleep diary-based minutes to fall asleep (p=.01), and feeling more rested in the morning (p=.02). Compared with general health education, a 12-month moderate-intensity exercise program that met current physical activity recommendations for older adults improved some objective and subjective dimensions of sleep to a modest degree. The results suggest additional areas for investigation in this understudied area.

    ABSTRACT: African-American girls and women are at high risk of obesity and its associated morbidities. Few studies have tested obesity prevention strategies specifically designed for African-American girls. This report describes the design and baseline findings of the Stanford GEMS (Girls health Enrichment Multi-site Studies) trial to test the effect of a two-year community- and family-based intervention to reduce weight gain in low-income, pre-adolescent African-American girls. Randomized controlled trial with measurements scheduled in girls' homes at baseline, 6, 12, 18 and 24 month post-randomization. Low-income areas of Oakland, CA. Eight, nine and ten year old African-American girls and their parents/caregivers. Girls are randomized to a culturally-tailored after-school dance program and a home/family-based intervention to reduce screen media use versus an information-based community health education Active-Placebo Comparison intervention. Interventions last for 2 years for each participant. Change in body mass index over the two-year study. Recruitment and enrollment successfully produced a predominately low-socioeconomic status sample. Two-hundred sixty one (261) families were randomized. One girl per family is randomly chosen for the analysis sample. Randomization produced comparable experimental groups with only a few statistically significant differences. The sample had a mean body mass index (BMI) at the 74 th percentile on the 2000 CDC BMI reference, and one-third of the analysis sample had a BMI at the 95th percentile or above. Average fasting total cholesterol and LDL cholesterol were above NCEP thresholds for borderline high classifications. Girls averaged low levels of moderate to vigorous physical activity, more than 3 h per day of screen media use, and diets high in energy from fat. The Stanford GEMS trial is testing the benefits of culturally-tailored after-school dance and screen-time reduction interventions for obesity prevention in low-income, pre-adolescent African-American girls.

    ABSTRACT: To describe several recruitment parameters derived from the Lifestyle Interventions and Independence for Elders pilot (LIFE-P) study for use in a full-scale trial of mobility disability prevention. A description of the recruiting methods and baseline characteristics of a four-site randomized, controlled trial testing the effectiveness of a physical activity intervention at preventing mobility disability. The Cooper Institute, Dallas, Texas; Stanford University, Stanford, California; University of Pittsburgh, Pittsburgh, Pennsylvania; and Wake Forest University, Winston-Salem, North Carolina. Community-living persons aged 70 to 89 who were able to walk 400 m within 15 minutes and were at high risk for disability (scoring<10 on the Short Physical Performance Battery (SPPB)) but without comorbidity severe enough to preclude full study participation. Measures of efficiency included number of randomized participants per recruitment technique and costs per randomized participant across randomization techniques. The 9-month recruiting period resulted in 3,141 telephone screens, of which 424 (13.5%) participants were randomized (68.9% women, 25.7% minorities, 41.5% with SPPB scores<8). Forty percent of telephone-screened participants were excluded primarily because of regular participation in physical activity, health exclusions, or self-reported mobility disability. Of the 1,252 persons attempting the physical performance assessments, 41% scored above the SPPB cutoff. Of the 566 remaining eligible, 9.9% could not complete the 400-m walk, and another 18.9% had various medical exclusions. Direct mailing was the most productive recruitment strategy (61.6% of all randomized participants). Recruitment cost approximately $439 per randomized participant. The LIFE study achieved all recruitment goals and demonstrated the feasibility of recruiting high-risk community-dwelling older persons for trials of disability prevention in diverse geographic areas.

    ABSTRACT: Ethnic minorities or those with low socioeconomic status (SES) are at increased risk of cardiovascular disease, type 2 diabetes, and all-cause mortality, compared to higher SES Whites. National surveys also indicate that low-income, ethnic minority women have the highest rates of inactivity in the United States. This study (the Increasing Motivation for Physical ACTivity or IMPACT study) promoted adoption and maintenance of physical activity (PA) in sedentary, low-income women participating in federally funded job training programs. The study consisted of 2 months of weekly 1-hr classes, then random assignment to 10 months of either home-based telephone counseling for PA plus information and feedback via mailed newsletters (Phone + Mail Counseling condition) or just the mailed newsletters (Mail Support condition). The IMPACT intervention included behavior change strategies for PA as well as discussions related to motivational readiness for PA change. Participants completed surveys and physiological assessments at baseline after the classes ended (i.e., at 10 weeks) and at 6 and 12 months postbaseline. Seventy-three percent of randomized participants (n = 72) were Latina, with a mean age of 32 +/- 10 years. More than half the women had not completed high school, and 73% had an annual income less than 20,000 dollars. After 10 months of a home-based intervention, women in the phone + mail counseling condition had significantly greater increases in estimated total energy expenditure compared to women in the mail support condition (p < .05). Regular PA counseling delivered via the telephone and through the mail appears effective for encouraging regular PA among low-income women transitioning from welfare or job training to the workforce.

    ABSTRACT: Researchers who conduct physical activity (PA) intervention studies provide an invaluable opportunity to further the prevention science knowledge base for implementing and delivering PA programs. Despite recommendations that screening is important to increase patient safety, the specific screening criteria best suited for different community applications are unknown. To add to the limited knowledge base, we examined the screening procedures and the occurrence of adverse events among more than 5,500 participants from 11 diverse PA interventions participating in a trans-National Institutes of Health (NIH) collaborative known as the Behavior Change Consortium (BCC). Numerous adverse events occur in sedentary, chronically ill, or older populations, although few are attributed to activity/exercise interventions. No serious study-related adverse events (SRAEs) were reported across different screening practices, interventions, and/or populations. Relatively few minor SRAEs were reported (primarily musculoskeletal injuries), emphasizing the need to be aware of potential musculoskeletal sequelae during exercise interventions. One common characteristic of these studies is that they recommended "start low and go slow" strategies, with moderate intensity PA as the goal behavior. Recommendations to reframe the meaning and use of screening criteria to initiate PA in the community are discussed. Although we were unable to conduct generalizable quantitative analyses from our data, the combined experience of the BCC studies provides a unique opportunity to examine PA-related screening and safety issues across diverse populations, settings, and intervention programs.

    ABSTRACT: Our goal was to examine 12-week covariability in diet and physical activity changes among 8- to 10-year-old African-American girls and if these changes predicted percent change in BMI. Covariability among percent changes [(post - pre)/pre x 100] in nutrients, food groups, and physical activity was assessed among 127 8- to 10-year-old African-American girls. Pearson correlation and hierarchical linear regression analyses were performed. Percent change in percentage kilocalories from carbohydrate was negatively correlated with percent change in both percentage kilocalories from fat (r = -0.85; p < or = 0.01) and protein (r = -0.51; p < or = 0.01). No statistically significant relationships were observed in percent changes among food group variables. Negative relationships were observed between percent changes in fruit/100% juice and percentage kilocalories from fat (r = -0.20; p < or = 0.05) and between percent changes in minutes of moderate-to-vigorous and sedentary activity (r = -0.60; p < or = 0.01). No significant associations were observed between percent change in moderate-to-vigorous physical activity and diet variables or percent change in BMI or waist circumference and percent change in diet or physical activity. No relationships were observed between percent changes in physical activity and dietary variables. Percent change in diet and/or physical activity did not predict percent change in BMI. This may have been due to the small sample size, the small changes in diet or physical activity, the short duration of the intervention, or because data from different interventions were combined. Understanding these relationships could have significant implications for addressing the obesity epidemic.

    ABSTRACT: To examine the cross-sectional relationships between physical activity and dietary behaviors among 8- to 10-year-old African-American girls. Two hundred ten 8- to 10-year-old African-American girls from four field centers participated. Computer Science and Applications (CSA) activity monitors were worn for 3 days. CSA data were expressed as mean CSA counts per minute, mean minutes of moderate to vigorous activity per day, and mean metabolic equivalents (METS) per minute. Two nonconsecutive 24-hour dietary recalls were analyzed for kilocalories; percent kilocalories from fat; daily servings of fruit, 100% fruit juice, and vegetables; sweetened beverages; and water consumption. Height and weight were measured, and information on household income, material possessions, and participant age were obtained. All three expressions of physical activity were significantly negatively associated with percentage calories from fat (r = -0.147 to -0.177, p < 0.01), and mean METS per minute were significantly positively associated with percentage calories from carbohydrate (r = 0.149, p < 0.05) after controlling for household income, material possessions, field center, and total caloric intake. Income was inversely associated with percentage calories from fat. Physical activity and dietary fat consumption were inversely related among African-American girls. Efforts to prevent obesity in preadolescent African-American girls should focus on increasing physical activity and lowering dietary fat consumption.

    ABSTRACT: This paper presents reliability and validity analyses of physical activity-related psychosocial questionnaires completed by 8- to 10-year-old African-American girls at baseline and follow-up assessments of pilot intervention studies in the Girls health Enrichment Multi-site Study (GEMS). Two hundred ten girls participated in the GEMS 12-week pilot studies and had their height and weight measured, wore an accelerometer for 3 days and completed a measure of their usual physical activity (PA) at baseline and after the 12-week intervention. Subgroups of girls also completed physical activity-related psychosocial measures at these two time points including: (a) self-concept; (b) self-efficacy; (c) outcome expectancies; and d) preferences. Principal components analysis was conducted on the psychosocial measures obtained at baseline. Cronbach's alpha and test-retest reliability were computed. Convergent validity was assessed by correlating the baseline psychosocial measures with baseline physical activity measures and body mass index (BMI). The following sub-scales were derived: Activity Preference, Positive Expectancies and Negative Expectancies for physical activity. Physical Performance Self-Concept and Self-Efficacy for physical activity were kept as single dimensional scales. Sub-scales, derived from principal components analyses, were Activity Preference, Positive Expectancies, and Negative Expectancies for physical activity. Internal consistency estimates for the various scales were substantial to excellent (0.67-0.85), while test-retest reliability estimates were fair to moderate (0.22-0.56). Correlations between the PA psychosocial sub-scales and measured levels of activity measures showed evidence of convergent validity for the Activity Preference sub-scale, although social desirability may have influenced the significant associations observed. The Activity Preference was a fairly reliable and valid measure. Further studies are needed to examine the utility of activity-related psychosocial measures in interventions to increase physical activity among preadolescent African-American girls.

    ABSTRACT: Valid and reliable physical activity checklists are needed to assess effectiveness of interventions. This study tested the validity and reliability of the Girls health Enrichment Multi-site Studies (GEMS) Activity Questionnaire. Two-hundred and ten African-American girls completed the GEMS Activity Questionnaire (GAQ), a checklist of 28 physical and 7 sedentary activities, including TV viewing, inquiring whether performed on the previous day ("yesterday"), and whether usually performed ("usual"). The girls wore an accelerometer (used as the criterion for validity) for three consecutive days at baseline and after a 12-week pilot intervention. Data from 172 girls at baseline and follow-up were usable for this report. Girls were (mean +/- SD) 8.8 +/- 0.8 years old with a BMI of 22.3 +/- 5.9 kg/m2. The intraclass correlation (ICC) examining reliability for the accelerometer across 3 days at baseline for the combined group was fair (ICC = 0.33, P < 0.21). The test-retest reliability coefficient for the 18-item MET-weighted GAQ yesterday scores for the comparison group of girls was 0.57 (P < 0.001). At baseline and follow-up, nonsignificant correlations were observed between 3-day accelerometer counts/minute and GAQ 18-item usual score for both comparison and intervention groups. A significant correlation was found between change in accelerometer minutes of moderate-to-vigorous activity (MVPA) between 12 noon and 6 PM and change in GAQ physical activities in the comparison girls (R = 0.35, P < 0.01). The TV-usual score was correlated with 3-day accelerometer counts/minute (R = -0.19, P = 0.02) at baseline for the total sample. Correlations between the GAQ and accelerometer were low, indicating low validity. Although the GAQ may be helpful in describing types of physical activities performed, it needs further development to improve its psychometric properties.

    ABSTRACT: To test the feasibility, acceptability, and potential efficacy of after-school dance classes and a family-based intervention to reduce television viewing, thereby reducing weight gain, among African-American girls. Twelve-week, 2-arm parallel group, randomized controlled trial. Low-income neighborhoods. Sixty-one 8-10-year-old African-American girls and their parents/guardians. The treatment intervention consisted of after-school dance classes at 3 community centers, and a 5-lesson intervention, delivered in participants' homes, and designed to reduce television, videotape, and video game use. The active control intervention consisted of disseminating newsletters and delivering health education lectures. Implementation and process measures, body mass index, waist circumference, physical activity measured by accelerometry, self-reported media use, and meals eaten with TV. Recruitment and retention goals were exceeded. High rates of participation were achieved for assessments and intervention activities, except where transportation was lacking. All interventions received high satisfaction ratings. At follow up, girls in the treatment group, as compared to the control group, exhibited trends toward lower body mass index (adjusted difference = -.32 kg/m2, 95% confidence interval [CI] -.77, .12; Cohen's d = .38 standard deviation units) and waist circumference (adjusted difference = -.63 cm, 95% CI -1.92, .67; d = .25); increased after-school physical activity (adjusted difference = 55.1 counts/minute, 95% CI -115.6, 225.8; d = .21); and reduced television, videotape, and video game use (adjusted difference = -4.96 hours/week, 95% CI -11.41, 1.49; d = .40). The treatment group reported significantly reduced household television viewing (d = .73, P = .007) and fewer dinners eaten while watching TV (adjusted difference = -1.60 meals/week, 95% CI -2.99, -.21; d = .59; P = .03). Treatment group girls also reported less concern about weight (d = .60; P = .03), and a trend toward improved school grades (d = .51; P = .07). This study confirmed the feasibility, acceptability, and potential efficacy of using dance classes and a family-based intervention to reduce television viewing, thereby reducing weight gain, in African-American girls.

    ABSTRACT: Although many primary care patients are inactive, being able to classify even small amounts and intensities of activity and factors associated with these activity levels could be helpful for physicians who are trying to motivate their patients to become more physically active. Sociodemographics, physical activity, fitness, other cardiovascular risk factors, and psychosocial measures were measured at baseline in the 874 patients in the Activity Counseling Trial. Patients were categorized into three groups: (1) no moderate-to-vigorous physical activity (MVPA), (2) some moderate but no vigorous activity, and (3) some vigorous activity. Multiple logistic regression was used to determine factors cross-sectionally associated with activity intensity. One or more cardiovascular risk factors in addition to physical inactivity were present in 84% of participants. Maximal oxygen uptake averaged 25.2 ml/kg/min; 85% had poor to fair aerobic fitness. Physical activity averaged 32.7 kcal/kg/day, with 13.5 min of MVPA/day; 26% engaged in some vigorous activity, 11% engaged in no MVPA. In unadjusted analyses, gender, age, race, education, income, employment, smoking, alcohol use, and exercise self-efficacy were associated with activity intensity (P = 0.05-0.001). A greater percentage engaged in moderate than in vigorous activity in all subgroups. In multiple logistic regression analyses, odds ratios (95% confidence intervals) for engaging in vigorous activity were 0. 39 (0.28, 0.56) for women, 0.38 (0.19, 0.75) for 65+ compared with 35- to 44-year-olds, and 1.14 (1.06, 1.22) for 10-unit increases in performance self-efficacy score. Most primary care patients who are physically inactive have additional cardiovascular risk factors, particularly overweight and obesity. All subgroups pursue moderate-intensity activity more often than vigorous activity. Women, older persons, and those with lower exercise self-efficacy are less likely to engage in vigorous activity.

    ABSTRACT: Examined factors associated with adults engaging in varying levels of physical activity. 874 primary health care patients (aged 35–75 yrs) completed questionnaires and underwent medical examinations concerning physical activity, cardiovascular risk factors, psychosocial measures, and demographic characteristics. Ss were categorized into the 3 groups of no moderate-to-vigorous physical activity (MVPA), some moderate but no vigorous activity, and some vigorous activity. Results show that Ss were generally a physically inactive and unfit patient population. Gender, age, race, education, income, employment, smoking, alcohol use, and exercise self-efficacy were associated with activity intensity. Gender, age, and performance self-efficacy were significantly associated with MVPA. It is concluded that physician advice that helps to build self-efficacy is an important counselling strategy.
