Background:

Although engaging in the recommended amount of physical activity provides disease-prevention benefits, few studies have examined the proportion and correlates of meeting the Japanese physical activity recommendation. This study investigated the prevalence and demographic correlates of attaining the recommended value on the Exercise and Physical Activity Reference for Health Promotion 2006.

Methods:

Data were analyzed for 5177 Japanese adults who took an Internet-based cross-sectional survey. The International Physical Activity Questionnaire and 6 possible demographic correlates were obtained. Respondents were divided into 3 groups—recommended, insufficient, and inactive—according to their estimated weekly physical activity level. A multivariate logistic regression analysis was used.

Results:

Overall, 26.6% of respondents were physically active according to the recommendation criterion. Gender, employment status, age, marital status, and educational level were statistically significant. In men, being employed and in women, being 30 to 39 years of age were negatively associated with the attainment of the recommendation. Being male, being a married woman, and having a college education or higher for women were positively correlated with the attainment of the recommendation.

Conclusions:

Different associations of demographic correlates with the physical activity recommendation for men and women were found, suggesting that gender-specific strategies for targeting the population or specific interventions might be more effective in promoting physical activity among Japanese adults.

Background: This investigation sought to determine how accelerometer wear (1) biased estimates of sedentary behavior (SB) and physical activity (PA), (2) affected misclassifications for meeting the Physical Activity Guidelines for Americans, and (3) impacted the results of regression models examining the association between moderate to vigorous physical activity (MVPA) and a clinically relevant health outcome. Methods: A total of 100 participants [age: 20.6 (7.9) y] wore an ActiGraph GT3X+ accelerometer for 15.9 (1.6) hours per day (reference dataset) on the hip. The BOD POD was used to determine body fat percentage. A data removal technique was applied to the reference dataset to create individual datasets with wear time ranging from 15 to 10 hours per day for SB and each intensity of PA. Results: Underestimations of SB and each intensity of PA increased as accelerometer wear time decreased by up to 167.2 minutes per day. These underestimations resulted in Physical Activity Guidelines for Americans misclassification rates of up to 42.9%. The regression models for the association between MVPA and body fat percentage demonstrated changes in the estimates for each wear-time adherence level when compared to the model using the reference MVPA data. Conclusions: Increasing accelerometer wear improves daily estimates of SB and PA, thereby also improving the precision of statistical inferences that are made from accelerometer data.

Background: The World Health Organization recommends 150 minutes of moderate to vigorous physical activity (PA) throughout the week. However, the weekly frequency of PA and how to combine moderate and vigorous PA to define who reaches the recommended PA are controversial. PA level might be highly different based on the recommendation and/or the criteria employed. Methods: Demographic data and PA level evaluated by International Physical Activity Questionnaire from 3 random and representative samples from 1 state, 1 city, and 1 local organization in Brazil were analyzed (n = 2961). Nine criteria from different recommendations were used to define PA level. Prevalence estimates and 95% confidence intervals of sufficient PA were calculated for each criterion and compared with the referent (World Health Organization guideline). Total agreement, sensitivity, and specificity were also calculated with 95% confidence interval. Results: When a weekly frequency of PA was required, the prevalence of sufficient PA decreased by 11% (P < .05). For all criteria, doubling the vigorous PA minutes was similar to simply adding them to moderate PA. These findings are consistent regardless of sex, age, and educational level. Conclusion: Prevalence estimates and agreement between different PA recommendations were significantly affected when a minimum frequency was required but did not change when vigorous PA minutes were doubled.

Background:

Little is known about the relationship between children’s physical activity (PA) in preschool (in-school) and outside of preschool (out-of-school). This study described this relationship.

Methods:

Participants were 341 children (4.6 ± 0.3 years) in 16 preschools. Accelerometers measured moderate-to-vigorous physical activity (MVPA) and total physical activity (TPA) in-school and out-of-school. In the full sample, Pearson correlation was used to describe associations between in-school and out-of-school PA. In addition, children were categorized as meeting or not meeting a PA guideline during school. MVPA and TPA were compared between the 2 groups and in-school and out-of-school using 2-way repeated-measures analysis of variance.

Results:

In the full sample, in-school and out-of-school PA were positively correlated for MVPA (r = .13, P = .02) and TPA (r = .15, P = .01). Children who met the guideline in-school remained comparably active out-of-school. However, those who did not meet the guideline were more active out-of-school than in-school. The groups were active at comparable levels while out-of-school. Identical patterns were seen for MVPA and TPA.

Conclusions:

Children’s in-school PA was positively associated with out-of-school PA. Children who did not meet the guideline in-school were more active out-of-school than in-school, suggesting preschool and classroom factors may reduce some children’s PA in-school.

Background:

Cancer survivors who engage in physical activity (PA) have improved quality of life, reduced fatigue, and lower mortality rates. We compare the percentage of cancer survivors meeting PA recommendations for US states, stratified by age and gender, to identify the need for PA education and intervention among cancer survivors.

Methods:

Pooled data from the 1997–2010 National Health Interview Survey were used to determine and rank age-adjusted PA by state. American Cancer Society guidelines (≥150 min/wk of PA) were used to compare prevalence by state, stratified by age group (< 65 and ≥65) and gender.

Results:

Thirty-three percent of cancer survivors met PA recommendations. The highest age-adjusted compliance to PA recommendations was in Vermont (59.9%, 95% confidence interval [CI], 40.8–76.3) and the lowest was in Louisiana (14.8%, 95% CI, 9.6–22.1) and Mississippi (15.5%, 95% CI, 10.4–22.3). The lowest percentages meeting recommendations were in Arkansas for males (8.6%, 95% CI, 7.0–10.6), Louisiana for females (12.5%, 95% CI, 6.8–21.9), Louisiana for survivors < 65 (15.6%, 95% CI, 10.5–22.6), and West Virginia for those ≥65 years (12.7%, 95% CI, 7.6–20.6).

Conclusions:

Meeting PA recommendations by cancer survivors varies markedly by state of residence. Future efforts should target states with low percentages, tailoring interventions to the special needs of this high-risk population. The importance of PA should be incorporated within cancer survivorship care plans.

Background:

Physical inactivity and related health consequences are serious public health threats. Effective strategies to facilitate and support active-living opportunities must be implemented at national, state, and local levels. San Antonio, Texas, health department officials launched the Active Living Council of San Antonio (ALCSA) to engage the community in developing a 3- to 5-year plan to promote active living.

Methods:

A steering committee set preliminary ALCSA aims and established a multisector membership structure modeled after the US National Physical Activity Plan (NPAP). ALCSA adopted governance standards, increased knowledge of physical activity and health, and engaged in an 18-month collaborative master plan writing process.

Results:

ALCSA selected overarching strategies and evidence-based strategies for each societal sector and adapted strategies to the local context, including tactics, measures of success, and timelines. Community and expert engagement led to a localized plan reflecting national recommendations, the Active Living Plan for a Healthier San Antonio.

Conclusion:

Multisector collaborations among governmental agencies and community organizations, which were successfully developed in this case to produce the first-ever local adaptation of the NPAP, require clearly defined expectations. Lessons learned in ALCSA’s organizational and plan development can serve as a model for future community-driven efforts to increase active living.

Background:

Self-rated health (SRH) is a predictor of several clinical outcomes, including mortality. Physical activity is associated with SRH; however, the specific role that resistance training (RT) plays in this relationship is unknown. We explored the independent association between self-reported RT and SRH in a cross-sectional survey (National Physical Activity and Weight Loss Study; NPAWLS) conducted by the University of South Carolina Prevention Research Center in 2002.

Method:

Subjects were 9651 men and women (mean age 46.5 yrs) classified as having high or low SRH; and they were categorized into 2 groups: (1) meeting nationally recommended levels for RT (≥2 days/week); (2) not meeting levels (<2 days/week or no RT).

Results:

Meeting national recommendations was associated with male gender (P < .01), normal BMI (P < .01), and higher education (P < .01). When compared to individuals with low SRH, those with high SRH were 2 times as likely to meet recommended levels of RT (OR = 2.32; 95% CI = 1.96 to 2.76). The model modestly attenuated when fully adjusted for confounding variables, including other exercise (OR = 1.79; 95% CI = 1.49 to 2.15).

Conclusion:

This study identifies the specific positive relationship between RT and SRH, further supporting the health benefits of meeting the national recommendations for RT.

Background:

Evidence is building that strength training may reduce complications associated with cancer such as fatigue, muscle wasting, and lymphedema, particularly among breast and prostate cancer survivors. Population estimates are available for rates of aerobic physical activity; however, data on strength training in this population are limited. The objective of this study was to identify rates of meeting public health recommendations for strength training and aerobic activity among cancer survivors and individuals with no cancer history.

Methods:

Data from the Health Information National Trends Survey (HINTS), Iteration 4 Cycle 1 and Cycle 2 were combined to conduct the analyses. Missing data were imputed, and weighted statistical analyses were conducted in SAS.

Results:

The proportion of individuals meeting both strength training and aerobic guidelines were low for both cancer survivors and those without a history of cancer. The odds of meeting strength training guidelines were significantly lower for women with a history of any cancer except breast, compared with women with no history of cancer (OR: 0.70, 95% CI: 0.51−0.96).

Conclusions:

More work needs to be done to understand why women with cancers other than breast, may be less inclined to engage in aerobic physical activity and strength training.

Background:

Knowledge is required for people to make health decisions. It can be conjectured that knowledge of physical activity recommended levels can be a step to behavior change. This study examined the knowledge of physical activity guidelines of adolescents who were completing the secondary school.

Methods:

A survey was conducted with 2718 students (1613 girls), aged 16 to 18 years (Mean = 17.2 ± 0.2 years). Gender and age were self-reported and socioeconomic status was calculated based on parental occupation. Students were asked about frequency, duration, and intensity of physical activity to achieve the recommended level. Chi-square was applied to the results.

Results:

16.2% reported that physical activity should be practiced daily. For the duration component of the recommendation, 43.5% identified correctly that the minimum recommended is 60 min/day. The intensity component was correctly answered by 62.7%. Considering all the components of the recommendation, only 3.6% of the students were able to identify correctly the physical activity recommendation, with no differences between genders or among socioeconomic status.

Conclusions:

These results highlight the need for an effective communication strategy for disseminating the message to ensure that young people are aware of, and understand the physical activity guidelines.

Background:

Little is known about how leisure-time physical activity (LTPA) influences gestational weight gain (GWG) among body mass index (BMI) categories. The purpose of this study was to examine the relationship between pregnancy LTPA and the proportion of normal, overweight, and obese women who meet GWG recommendations.

Methods:

Participants included 449 subcohort women from the Pregnancy Outcomes and Community Health (POUCH) study. LTPA was collapsed into 3 categories [(None, < 7.5 kcal/kg/wk (low), ≥ 7.5 kcal/kg/wk (recommended)]. GWG was categorized according to IOM recommendations (low, recommended, or excess). Chi-square and logistic regression analyses were used to evaluate relationships among LTPA, BMI, and GWG.

Results:

Overweight women were more likely to have high GWG vs. normal weight women (OR = 2.3, 95% CI 1.3–4.0). Obese women were more likely to experience low GWG (OR = 7.3, 95% CI 3.6–15.1; vs. normal and overweight women) or excess GWG (OR = 3.5, 95% CI 1.9–6.5; vs. normal weight women). LTPA did not vary by prepregnancy BMI category (P = .55) and was not related to GWG in any prepregnancy BMI category (P = .78).

Conclusions:

Regardless of prepregnancy BMI, LTPA did not affect a woman’s GWG according to IOM recommendations. Results may be due to LTPA not differing among BMI categories.
