Influences of Outdoor Experiences During Childhood on Time Spent in Nature as an Adult.

Introduction: Time spent in nature provides myriad physical and mental health benefits for both adults and children. Despite these benefits, most people spend too little time in nature to realize the maximal effect. Different types of childhood experiences may have differential influence on adult time in nature. This study assessed the influences of different kinds of childhood outdoor experiences on time spent in nature as an adult. The first aim was to utilize 20 childhood nature experience items to construct summative scales. The second aim was to examine the influence of each scale and other factors on adult time in nature. Methods: A 2-factor scale measuring wild and domesticated childhood nature experiences was developed using principal and confirmatory factor analyses. An online study of 2,109 American adults was conducted. Multiple linear regression examined the influences of the 2 childhood nature experiences scales, attitude and self-efficacy scales, and sex and age covariates on adult time spent in nature. Results: Significant predictors of adult time in nature were wild childhood nature experiences (ß=0.279, p<0.001), positive attitudes about nature (ß=0.12, p<0.05), negative attitudes about nature (ß= -0.23, p<0.001), and self-efficacy (ß=0.71, p<0.001). Conclusions: Wild childhood nature experiences (e.g., camping, hiking, and fishing) that include skill building, that are immersive and engaging, and that involve opportunity for social interaction may translate better into adult nature activities. Programs that introduce and support wild experiences may increase lifelong time spent in nature.

Sociodemographic influences on youth sport participation and physical activity among children living within concentrated Hispanic/Latino rural communities.

Introduction: Lack of physical activity (PA) among children living in rural communities is a documented public health problem. Although studies have examined community conditions defined by a rural-urban dichotomy, few have investigated rural community conditions with a concentration of Hispanic/Latino people. This cross-sectional study examined sociodemographic characteristics associated with youth sport (YS) participation and daily PA among children living within concentrated Hispanic/Latino rural U.S. Midwest communities. Methods: During spring 2022, 97% of 3rd-6th grade children (n = 281, aged approximately 8-12 years) attending school in rural Midwestern communities (n = 2) with >50% concentration of Hispanic students participated in the Wellscapes Project, a community randomized trial. Participants completed the Youth Activity Profile and supplemental National Survey of Children's Health questions assessing PA behaviors and YS participation. Caregivers of a subsample of children (n = 215; males, n = 93; females, n = 122) consented to pair their child's survey results with school enrollment records (e.g., free/reduced lunch status and race and ethnicity). Mixed models with community as a random effect examined main and interaction effects of grade, sex, ethnoracial status, and family income on YS participation and these sociodemographic characteristics and YS participation on daily moderate-to-vigorous PA (MVPA). Results: Approximately half of children participated in YS. Non-Hispanic White children (n = 82) were over five times more likely to participate in YS than Hispanic peers (n = 133) (OR = 5.54, 95% CI = 2.64-11.61, p < 0.001). YS participants accumulated 8.3 ± 2.3 more minutes of daily MVPA than non-participants (p < 0.001). Sixth graders, females, and Hispanic children reported lower daily MVPA than comparison groups (p < 0.05). Significant interaction effects on daily MVPA between grade and ethnoracial status (F(3, 204) = 3.04, p = 0.030) were also found. Discussion: Disparities in sport participation and PA outcomes based on sociodemographic characteristics exist among children living in ethnoracially diverse rural communities. Strategies to promote YS participation, including community structural changes, may help reduce PA disparities. The research provides valuable insights for policymakers, public health professionals, and community members to address YS participation barriers, not limited to cost, while considering other PA-promotion efforts to improve child population health.

Shifts in Social Determinants of Vitamin A Supplementation Among Children Under Five in Kenya, 2003-2014.

OBJECTIVES: In Africa and Asia, 190 million preschoolers are vitamin A deficient. This study examined the social determinants of intake of vitamin A supplementation (VAS) among children aged 6-59 months during three different time periods in Kenya to identify those most vulnerable to vitamin A deficiency and highlight the varied targeting and outreach efforts; before the onset of a national restructuring and targeted distribution of VAS in children below 5 years through a twice-yearly door-to-door campaign called Child Health Weeks, during the implementation period, and several years later. METHODS: The cross-sectional, national Demographic and Health Surveys were administered in Kenya in 2003, 2008-09, and 2014. Bivariate and multivariable logistic regression analyses were used to assess variables associated with VAS among children (n = 28,239). RESULTS: An overall two-fold increase in VAS was recorded between 2003 (31.8%) and 2014 (67.5%). In 2008-09, children aged 6-11 months were the most likely to receive VAS. In 2003 and 2014, geographical regions and settings, birth order of the child, educational level of the mother, religion, wealth index, number of antenatal visits, and access to a radio were identified as being significantly associated with VAS, in at least one of the years. These determinants were not significant in 2008-09 during the initial Child Health Weeks promotion campaign. The determinants of VAS varied during the three study periods, particularly in 2008-09 when the Child Health Weeks was first implemented. CONCLUSION: As efforts to increase VAS continue, addressing child-specific determinants will be essential to reduce health disparities.

COVID-19 pandemic and changes in children's physical activity in a rural US community: a mixed methods study.

OBJECTIVES: To examine differences in rural community children's moderate-to-vigorous physical activity (MVPA) and participation in out-of-school activities from fall 2019 to fall 2020 and explore enacted PA opportunity modifications post initial COVID-19 disruption. DESIGN: Mixed methods study using the validated Youth Activity Profile (YAP), administrator reports and stakeholder surveys and semistructured interviews. SETTING: Children and community stakeholders from one rural US Great Plains community in the state of Nebraska were recruited. PARTICIPANTS: Third through fifth graders in fall 2019 (n=144) and fall 2020 (n=174) reported MVPA and participation in out-of-school activities using the YAP. School administrators reported weekly physical education (PE) and recess minutes. Community stakeholders reported pandemic-related changes in community social structures in semistructured interviews (n=4) and surveys (n=19). RESULTS: Average daily MVPA minutes increased from 2019 to 2020 (75.0 vs 81.3, SE=1.6, p<0.05). Minutes of MVPA increased during: school hours (MD=2.7, SE=0.5, p<0.5); out-of-school time on weekdays (MD=3.9, SE=1.3, p<0.5); and on weekends (MD=5.5, SE=2.4, p<0.5). On average, fewer children participated in youth sport (42.5% vs 47.2%), youth clubs (10.3% vs 16.0%) and other out-of-school activities (24.1% vs 38.2%) in 2020, compared with 2019. Weekly PE/recess minutes increased from 208.3 to 241.7 from 2019 to 2020. Stakeholder surveys revealed community-driven modifications to PA opportunities, and interviews suggested children played outside more frequently, especially when school was closed and out-of-school activities were shut down. CONCLUSIONS: Increased minutes of PE and recess, and decreased out-of-school activity participation may have increased children's overall free play and MVPA during the pandemic. Free play was an important contributor to children's PA during the pandemic and should be prioritised by educators, coaches and other leaders of child PA opportunities.

Rural community systems: Youth physical activity promotion through community collaboration.

A common way to address rural population health issues is through community stakeholders working together. Youth physical activity (PA) happens in adult-led in-school and out-of-school group opportunities that vary across communities and generally occur in isolated settings. This study explores similarities and differences in rural community system structure and collaborative process variables that help to conceptualize the collaborative impact influencing population youth PA outcomes. Stakeholders (Community 1, n = 23; Community 2, n = 26) and youth (Community 1, n = 205; Community 2, n = 213) were recruited in 2018-2019 as part of Wellscapes, a hybrid implementation-effectiveness community randomized trial. A stakeholder survey (n = 49) measured community system structures and collaboration processes. Youth completed the Youth Activity Profile to measure PA levels. More Community 1 respondents than Community 2 resided within city limits (73.9% vs. 34.6%). Collective efficacy was significantly greater in Community 1 (M = 4.0, SD = 0.5) than in 2 (M = 3.2, SD = 0.4), p < 0.05. Perceptions of trust scored significantly greater in Community 1 (M = 4.1, SD = 0.3) than in 2 (M = 3.3, SD = 0.5), p < 0.05. Though both communities met rural definitions and had stakeholder investment, Community 1 had a greater proportion of PA-implementing stakeholders and more residing within city limits which may have influenced that community's higher scores in collective efficacy and trust. Community 2 had more stakeholders in administrator roles and yielded greater youth PA levels. Unique and common variables of rural communities should be considered in understanding system factors that impact youth PA.

Youth sport participation and physical activity in rural communities.

BACKGROUND: Physical activity, a high-frequency health behavior, varies by where children live, learn, and play. Children accumulate physical activity in adult-led in-school and out-of-school settings. Youth sport is a potential setting for physical activity, but there are differences in youth sport participation based on age, sex, and socioeconomic status. There is a gap in understanding demographic influences on youth sport participation and how these factors interact to influence physical activity. This study examines influences of grade, sex, and family income on youth sport participation and these factors and youth sport participation on moderate-to-vigorous physical activity of children in rural communities. METHODS: Children (n = 418 3rd-6th graders) living in two rural communities completed the online Youth Activity Profile as part of Wellscapes, a type 3 hybrid implementation-effectiveness community randomized trial. Mixed models with community as a random effect examined main effects and interactions of grade, sex, and family income on youth sport participation and these factors and youth sport participation on moderate-to-vigorous physical activity. RESULTS: About 80% of children engaged in youth sport, and full-pay lunch students were almost four times more likely to have youth sport participation than students with free/reduced lunch (OR = 3.91, 95% CI = 1.95, 7.8). Females and 6th graders (p < 0.05) had lower physical activity than comparison groups. Males with higher family income had greater physical activity; females with higher family income had less physical activity. For 6th graders, high family income had less effect on physical activity than similar 3rd-5th graders (p < 0.01). CONCLUSIONS: While a fairly high percentage of children participate in youth sports, there are disparities in rural communities on youth sport participation and physical activity outcomes based on age, sex, and family income.

Household motor vehicle ownership and obesity among Indian females and males: 2005-2016.

BACKGROUND: To determine associations between household motor vehicle ownership and obesity among Indian adults. METHODS: Bivariate and multivariable analyses were conducted using the 2005-2006 and 2015-2016 Indian Demographic and Health surveys, with over 800 000 respondents. RESULTS: Obesity prevalence (body mass index ≥25 kg/m2) rose in females (16.87% to 20.35%) and in males (12.55% to 18.74%). In 2005, having both types of vehicles (motorcycle/motor scooter and car) significantly increased the odds of obesity in females (OR, 1.63; 95% CI 1.50 to 1.76) and males (OR, 2.49; 95% CI 2.24 to 2.77) as well as in 2015 (OR, 1.10; 95% CI 1.07 to 1.13 and OR, 1.56; 95% CI 1.45 to 1.68, respectively). The wealthiest were more likely to be obese in 2005 (OR, 14.95; 95% CI 16.06 to 17.12 for females; OR, 12.69; 95% CI 10.17 to 15.70 for males) and in 2015 (OR, 7.69; 95% CI 7.43 to 7.95 for females and OR, 6.40; 95% CI 5.40 to 7.01 for males). Higher education levels, being younger and rural residence were significant protective factors in 2005 and 2015. CONCLUSIONS: After adjusting for confounders, motor vehicle ownership was significantly associated with obesity at both time points, but the effect of vehicle ownership presents differently by gender. With obesity prevalence increasing in India, policies promoting active vs motorized transport could attenuate this problem.

A Scoping Review of Bikeability Assessment Methods.

Bicycling holds promise as a healthy and sustainable means of transportation and physical activity. Despite the growing interest in community-based environmental approaches to promoting physical activity, bikeability has received relatively little attention. This paper provides a scoping review of the instruments developed to measure bikeability along with practice-based analyses of the tools related to user expertise, estimated cost, and required time to implement. The review summarizes the literature, identifies research gaps, and informs stakeholders with articles from EBSCO and transportation databases published after 2003 when the previous bikeability instrument review paper was published. Data extraction included the tool name, data collection method, study location, data collection scale, type of measure, and description. Two reviewers independently reviewed articles included in the full text review, and the inter-rater agreement exceeded 90%. The database search yielded 388 unique articles, and 17 met the inclusion/exclusion criteria. Most of the studies, 11 of 17, were applied to settings outside of the U.S. Five studies employed a self-report survey, and five studies examined bikeability using geospatial data, like GIS. Seven studies used a direct observation audit tool-one specifically using a mobile app and another using virtual observation techniques with Google Street View. Bikeability tools are useful for assessing communities and their supports for bicycling. Our primary finding is that advances in technology over the past two decades have driven innovative and useful methodologies, in a variety of disciplines, for assessing the environment, but more consensus is needed to provide a universal definition of bikeability.

Gender differences in the relationship of sexual partnership characteristics and inconsistent condom use among people living with HIV in China.

Few studies have examined the relationship between inconsistent condom use and sexual partnership characteristics among people living with HIV (PLWH). The current study focused on such association and its gender differences. The study was conducted in a large hospital in South China in 2013. A total of 320 dyads (PLWH indexes and their sexual partners) were recruited from an outpatient clinic using convenience sampling. The proportion of inconsistent condom use in the last six months among female indexes was higher than that among male indexes (52.4% vs. 43.6%). Of sexual partnership characteristics, HIV seropositive status was a risk factor for inconsistent condom use for both male and female indexes (aOR = 2.32, 95%CI = 1.15∼4.66, aOR = 3.09, 95%CI = 1.10∼8.67, respectively). For male indexes, lower educational level was also a risk factor (aOR = 2.39, 95%CI = 1.23∼4.67); while having had emotionally intimate relationships was a protective factor (aOR = 0.40, 95%CI = 0.21∼0.77). For female indexes, receiving material support was a risk factor (aOR = 10.17, 95%CI = 2.13∼48.61) and receiving health-related advice was a protective factor (aOR = 0.11, 95%CI = 0.02∼0.55). Future HIV interventions for PLWH need to be gender-sensitive and include their sexual partners.

Testing Usability and Acceptability of a Web Application to Promote Physical Activity (iCanFit) Among Older Adults.

BACKGROUND: Most older Americans do not exercise regularly and many have chronic conditions. Among an increasing number of fitness mobile and Web apps, few are designed for older adults with chronic conditions despite high ownership rates of mobile tools and Internet access in this population. We designed a mobile-enabled Web app, iCanFit, to promote physical activity in this population. OBJECTIVE: This study aimed to test the usability and acceptability of iCanFit among older adults in a community setting. METHODS: A total of 33 older adults (aged 60 to 82 years) were recruited from communities to test iCanFit. Of these 33, 10 participants completed the usability testing in a computer room of a senior community center. A research assistant timed each Web application task and observed user navigation behavior using usability metrics. The other 23 participants used the website on their own devices at home and provided feedback after 2-3 weeks by completing a user-experience survey assessing ease of use, helpfulness, and satisfaction with iCanFit. RESULTS: Participants completed all 15 tasks on the iCanFit site in an average of 31 (SD 6.9) minutes; some tasks required more time or needed assistance. Participants' comments were addressed to improve the site's senior friendliness and ease of use. In the user-experience survey, participants reported high levels of usefulness and satisfaction. More than 56% (13/23) of participants indicated they would continue using the program and recommend it to their families or friends. CONCLUSIONS: Testing usability and acceptability is a very important step in developing age-appropriate and user-friendly Web apps, especially for older adults. Testing usability and acceptability in a community setting can help reveal users' experiences and feedback in a real-life setting. Our study suggested that older adults had a high degree of acceptance of iCanFit and could use it easily. The efficacy trial of iCanFit is currently underway.
