RESUMEN

Physical activity can help improve the poor health-related quality of life in older adult population. Although the Physical Activity Guidelines for Americans recommend both aerobic and muscle strengthening activities for adults, previous studies predominantly focused on aerobic activity with limited research on muscle strengthening activities. The purpose of this cross-sectional study was to examine the relationships between meeting physical activity guidelines (i.e., aerobic activity, muscle strengthening activity) and health-related quality of life in the older adult population. Data of 87,495 older adults aged ≥65 years from the U.S. 2019 Behavioral Risk Factor Surveillance System were analyzed. Phone interviews and validated questionnaires were used to assess aerobic activity, muscle strengthening activity, and health-related quality of life. Binomial logistic regression was used to examine the relationships between meeting physical activity guidelines and health-related quality of life while adjusting for key covariates (i.e., age, sex, race, education, marital status, employment status, income, body mass index, smoking, drinking, and comorbidities). Participants meeting both or aerobic activity guideline only had significantly lower odds of reporting all components of health-related quality of life (i.e., general health, mental health, physical health, activity limitation) than those who met neither guideline (OR = 0.37-0.58) and those who met muscle strengthening activity guideline only (OR = 0.34 - 0.74). Given the stronger positive association between aerobic activity and health-related quality of life than that between muscle strengthening activity and health-related quality of life, future research should focus on promoting aerobic activity to increase health-related quality of life among older people.

RESUMEN

The purpose of this qualitative study was to describe the factors that influence adolescent and adult perceptions and attitudes related to adolescent diet in Botswana. A series of 15 focus groups [12 adolescent focus groups (6 male and 6 female) & 3 parent focus groups] of approximately six to eleven members each were conducted in Gaborone, the capital city of Botswana in 2009-2010. Adolescents and parents of adolescents suggest that the main drivers of adolescent food choices have much to do with where the adolescent is in terms of time of day as well as with whom the adolescent is with. Outside of the home adolescents suggest that the real or perceived influence of companions place social standing on the ability to purchase and consume non-traditional foods, and that traditional foods leave adolescents open to ridicule. Additionally parents of adolescents suggest that while they prefer for their children to consume healthy foods, they frequently purchase unhealthy food items for their children based on the child's taste preferences as well as social influence to prove you can buy "nice things" for one's family. Adolescents and parents of adolescents suggest that increasing the availability and decreasing the costs of healthy food options are preferred possible interventions to increase healthful eating among adolescents. However, the adolescents also suggest that these healthy food options should not crowd out or completely replace unhealthy options, thus preserving the adolescents' freedom to choose. This could pose a major challenge in any school-based adolescent obesity prevention program.

RESUMEN

Background: Emerging research indicates that the COVID-19 pandemic and associated restrictions led to decreased physical activity levels and poorer health globally. However, most studies on this topic have focused on advanced countries, leaving a gap in understanding the impact in countries like Ghana. This study aimed to fill this gap by assessing self-perceived health status and physical activity levels among youth and adults in Ghana before, during, and after the COVID-19 restrictions. Understanding these dynamics is crucial for informing public health interventions and policies to promote well-being during and beyond the pandemic. Methods: A cross-sectional survey using online data collection methods was conducted, involving 937 participants. Data included demographic information, and International Physical Activity Questionnaire-Short Form (IPAQ-SF). Analysis was done using SPSS version 25, with descriptive statistics and multinomial regression. Results: Most participants (89.6%) reported good health. Male participants were significantly more likely to engage in moderate (1.78 times) and high (3.17 times) physical activity during the COVID-19 period compared to females. Conclusion: This study highlights gender disparities in physical activity levels during the pandemic in Ghana. Addressing these disparities and promoting healthier lifestyles, especially during crises, is crucial for general and mental health. Further research should explore socio-demographic factors' role in health behaviors during pandemics.

RESUMEN

Healthy lifestyle levels are low among adults with hypertension (HTN). Unfortunately, psychosocial factors contributing to patients' inability to meet healthy lifestyle recommendations are not well-understood. This integrative review examined the relationships of three psychosocial factors (self-efficacy, outcome expectancy, and social support) with dietary adherence (DA) and physical activity (PA) among adults with HTN. In total, 24 peer-reviewed studies were assessed. Results showed self-efficacy had small-to-large relationships with PA (r = 0.02-0.46) and DA (r = 0.06-0.79), with the strength of the associations varying by the assessed domain and country of origin. However, few studies reported a small relationship between the remaining factors (outcome expectancy and social support) and PA and DA. Thus, more efforts are needed to delineate the contributions of social support and outcome expectancies on DA or PA. When designing an intervention that focuses on improving PA or DA among adults with HTN, these psychosocial factors should be targeted.

RESUMEN

Guided by the Sport-Confidence Model, this study examined the associations among a positive body image, sport-confidence, and sport performance evaluations. Using a cross-sectional design, a purposive sample of 314 Jamaican athletes (male = 70.7%; Mage = 22.85; SD = 4.89) completed measures of body and functionality appreciation, sport-confidence, and subjective sport performance. Results from path analysis provided evidence for good model-data fit. Body (B = 9.03, p < .001) and functionality (B = 4.93, p = .036) appreciation exerted direct effects on sport-confidence. Sport-confidence exerted a direct effect on sport performance evaluations (B = 0.09, p < .001). Body (B = 0.79, CI95% [0.44, 1.17]) and functionality (B = 0.43, CI95% [0.05, 0.92]) appreciation exerted indirect effects on sport performance evaluations through sport-confidence. Results indicate that supporting the development of a positive body image in athletes may contribute to feelings of sport-confidence and positive performance outcomes.

RESUMEN

The study's objectives were to gain school personnel's (1) perceptions on diet, physical activity, body size, and obesity, (2) description of school food and physical activity practices, and (3) recommendations for programs to prevent adolescent obesity. The study took place in six junior secondary schools of varying socioeconomic status in Gaborone, Botswana. Using a qualitative descriptive design, semistructured interviews were conducted with key school personnel. Directed content analysis was used to summarize the findings. School personnel believed that obesity was an important problem. They felt that school food was unhealthy and that physical activity was provided insufficiently. Participants shared enthusiasm for a school-based health-promoting intervention that must be fun and include active engagement and education on healthy lifestyles for all students. Participants supported on-site food shop inventory changes and physical activity programs. Potential barriers listed were schools' financial resources, interest of students, and time limitations of all involved.

RESUMEN

BACKGROUND: Growing evidence of lower physical activity (PA), higher sedentary behavior, and prevalence of overweight and obesity in African countries calls for more research on PA behavior and its various correlates in this context. This study examined the proportion of adults meeting World Health Organization PA guidelines from 3 urban regions of Botswana, as well as the relationship among sociodemographic factors, body image, and participation in moderate to vigorous PA. METHODS: Using a 2-stage stratified cluster sampling approach, cross-sectional data were collected from 699 participants (females = 66%; M = 32.60 y; SD = 11.96). RESULTS: Overall, 45.8% of participants met World Health Organization PA guidelines. Censored regression analyses indicated that females (B = -221.573, P < .001), and individuals from middle- (B = -331.913, P < .001), and high-income (B = -165.185, P = .036) households spent significantly less minutes in moderate to vigorous PA per week. Evaluative (B = -333.200, P < .001) and affective (B = -158.753, P = .038) components of body image were associated with significantly less minutes spent in moderate to vigorous PA per week. CONCLUSIONS: A systematic approach to PA promotion that targets females, middle- to high-income groups, and individuals experiencing body image concerns is needed.

RESUMEN

With the growing interest in sport-based positive youth development (PYD) programs across the African continent, there is a need to establish suitable measures to evaluate the success of these programs in fostering PYD. The Life Skills Scale for Sport (LSSS) was recently developed as a sport-specific measure of life skills development. Despite its good psychometric properties among British youth sport participants, cross-cultural evidence indicates differences in the conceptualization of the eight factors measured by the LSSS. To determine the suitability of the LSSS for use in the African youth sport context, this study examined the latent structure and reproducibility of scores produced by the scale in a sample of youth sport participants from Botswana and Ghana. Cross-sectional data from a sample of 495 youth athletes (male = 51.72%), aged 12-21 years (M = 16.76, SD = 1.58), from junior and senior secondary schools was used in this study. Confirmatory factor analysis and exploratory structural equation modeling were conducted, and conventional fit indices were used to assess model fit. Results on the original LSSS model indicated the need for model re-specification in the current sample. A re-specified LSSS, consisting of the original eight factors, but only 34 of the original 43 items, demonstrated improved fit and adequate internal consistency. Scores derived from the re-specified LSSS proved to be a valid estimate of life skills development in the current sample of youth sport participants. This has important implications for the utility of the LSSS in different cultures.

RESUMEN

Sport-based life skills interventions offer compelling pathways to understanding the role of physical activity and sport on youth psychosocial and other development outcomes. This is because of evidence that shows the benefits of sport programs to health and well-being of youth, and more lately other areas such as academic achievement and various life skills such as teamwork, leadership and goal setting. However, much of the research in this area of youth development is largely descriptive, with limited capacity to infer causal relationships and application across contexts. Therefore, this study examines the effects of a sport-based intervention program on life skills and entrepreneurial mindsets of youth from three African countries (n = 146, average age = 15.9 years, female = 48.6%). Half of the recruited participants were assigned to a three-week life skills intervention program and the remaining half to a sport-only control program. Both groups completed a demographic information questionnaire, Life Skills for Sport Scale and the General Enterprising Tendency v2 test. Two-way mixed ANOVAs showed significant post-intervention changes in life skills for both groups but changes in entrepreneurial mindsets for the intervention group only. This demonstrates the relevance of sport-based interventions to youth development outcomes in different contexts and the transformative potential of youth sport reported in previous studies. The findings have important implications for intentional and targeted delivery of programs to enhance specific youth development outcomes.

RESUMEN

OBJECTIVE: To describe patterns of food consumption associated with overweight/obesity (OW/OB) and their links to socio-economic status (SES) and urbanization. DESIGN: A nationwide cross-sectional survey. SETTING: Secondary schools in cities, towns and villages in Botswana, Africa. SUBJECTS: A total of 746 adolescent schoolchildren. RESULTS: OW/OB is associated with greater SES, city residence and a snack-food diet pattern. Students belonging to higher SES compared with those from a lower SES background reported significantly (P < 0·01) more daily servings of snack foods (1·55 v. 0·76) and fewer servings of traditional diet foods (0·99 v. 1·68) and also reported that they ate meals outside the home more often (90% v. 72%). Students in cities ate significantly (P < 0·01) more servings of snacks (1·69 v. 1·05 v. 0·51) and fewer servings of traditional foods (0·67 v. 1·52 v. 1·61) compared with those in urban and rural villages. The odds of OW/OB were increased 1·16-fold with a snack-food diet, a result that was diminished when controlled for SES. CONCLUSIONS: These data suggest that nutritional transition occurs at different rates across urbanization and SES levels in Botswana. In cities, increasing the availability of fruit while reducing access to or portion sizes of snack items is important. Emphasis on continued intake of traditional foods may also be helpful as rural areas undergo economic and infrastructural development.

RESUMEN

The modeling and reinforcement of efficacy beliefs and mental toughness in sport continue to generate significant curiosity in the sport psychology research. Investigations into how these behaviors interact and, in the process, affect the development of prosocial and antisocial behaviors among youth athletes are relatively few. This is despite growing evidence of strong associations between self-efficacy beliefs, mental toughness, and various kinds of adaptive and maladaptive behaviors in sport. Therefore, this study sought to examine if mental toughness mediates the relationship between self-efficacy and prosocial/antisocial behaviors in Botswana youth athletes. The study also examined if data from Botswana fit the proposed factor structure of the Sports Mental Toughness Questionnaire, the Self-efficacy Scale, and the Prosocial and Antisocial Behavior in Sport scale. A total of 158 male (n = 81) and female (n = 77) junior secondary school and senior secondary school (middle and high school) athletes aged 14-20 years old enrolled in Centers for Sport Excellence in Botswana participated in the study. Results showed support for the factor structure of the study's measurement tools. The constancy dimension of mental toughness mediated the relationship between self-efficacy and prosocial/antisocial behavior to teammate and opponent. These findings have implications for research and practice aimed at enhancing efficacy beliefs, mental toughness, and positive youth sport experiences. Contextual relevance of this line of research and measurement tools are discussed.

RESUMEN

The coaching competency research has demonstrated the role of coaching efficacy and coaching behaviors on various athlete outcomes. However, athlete perceptions of these relationships and how they affect performance are less understood. PURPOSE: This study examined if coaching efficacy is predictive of player perceptions of coaches' leadership styles, team atmosphere, and team performance in a soccer season. METHOD: Fifteen male premier league soccer coaches (Mage = 45.27, SD = 6.07) and 226 players (Mage = 25.66, SD = 3.96) from Botswana participated in the study. All participants completed a background information questionnaire. Coaches completed the Coaching Efficacy Scale. Players rated their coaches' leadership styles using the Revised Leadership Scale for Sports as well as team atmosphere. Team performance was based on position in the league log and player ratings of the teams' performance. RESULTS: Findings showed that coaches' self-ratings on technique efficacy predicted player perceptions of the coaches' use of all six leadership styles. Game strategy efficacy predicted higher team atmosphere and team performance. Motivation efficacy was not significantly associated with player perceptions of the coaches' use of any of the leadership styles, while character building efficacy was negatively associated with the various leadership styles. CONCLUSION: Findings provide support to previous research evidence linking higher coaching efficacy, leadership styles, and team outcomes. The study expands the emergent research within the coaching competency literature that examines player perceptions of coaches' behaviors and leadership styles.

RESUMEN

Little is known about whether physical activity and fitness could enhance cognition in adolescents and young adults living with HIV. The purpose of this study was to examine this relationship in a group of 250 HIV+ (n = 88) and HIV negative (n = 162) participants from Botswana, aged 12-23 years (Mean = 17.87, SD = 2.24). Fitness was operationalized as muscular strength (push-ups) and aerobic endurance (PACER). PA was assessed using items from the Youth Risk Behavior Surveillance Survey. Cognition was measured using the Corsi Test, Berg Card Sorting Task (BCST), and Stroop Color Word Task (Stroop). Multiple regression analyses indicated that the HIV x push-ups interaction was a significant predictor of Corsi performance, and HIV status was a significant predictor of BCST performance (p < 0.05). For the Stroop portions, HIV status and HIV x push-ups were significant predictors (p < 0.01). HIV status is predictive of cognition and interacts with muscular fitness to predict cognition.

RESUMEN

The objectives of this study were to examine differences in physical activity behaviors as a function of human immunodeficiency virus (HIV) status and sex, to test differences in physical activity self-efficacy (PASE), body weight satisfaction (BWS), and enjoyment of physical activity as a function of HIV status, and to determine if PASE, BWS, and enjoyment are associated with daily physical activity (daily PA), muscle strengthening activities, and sedentary behavior of youth with and without HIV. A total of 250 HIV positive (HIV+) and HIV negative (HIV-) youth from Botswana aged 12-23 years (Mean = 17.87, SD = 2.24) participated in the study. The HIV+ group (n = 88) was recruited from a previous 12-month antiretroviral therapy (ART) and nutrition intervention study. The HIV- group (n = 162) was randomly selected from public junior and senior (secondary) high schools in and around Gaborone. Participants' PASE, BWS, enjoyment of physical activity, daily PA, muscle strengthening, body mass index (BMI), and sedentary behavior were obtained using items from the Youth Risk Behavior Surveillance Survey. Multivariate analysis of variance (MANOVA) showed that the HIV- group (M = 1.20, SE = 0.06, CI = 1.08 to 1.32) had significantly higher daily PA than the HIV+ group (M = 0.99, SE = 0.08, CI = 0.82 to 1.15). The HIV- group (M = 0.91, SE = 0.06, CI = 0.79 to 1.03) also reported participating significantly more in muscle strengthening activities than the HIV+ group (M = 0.63, SD = 0.08, CI = 0.47 to 0.78). Multiple regression analyses showed that higher PASE (p < .001) and greater enjoyment of PA (p < .01) were predictive of higher daily PA. HIV- participants had higher PASE but lower BWS compared to HIV+ participants. Sex and age differences were observed in muscle strengthening activities and sedentary behavior. This study supports previous findings on the association of efficacy beliefs to daily PA and muscle strengthening activities. The findings have implications for PA interventions aimed at health promotion and mitigation of the effects of living with HIV/AIDS.

RESUMEN

OBJECTIVE: Despite existing evidence about the benefits of nutrition, physical activity (PA) and sport to the overall health and wellbeing of children, knowledge gaps remain on this relationship in children living with chronic conditions like HIV/AIDS. Such knowledge should inform context specific programs that could enhance the quality of life of children. The purpose of this study was to examine the effects of integrating a nutrition intervention (culturally tailored food supplement) into antiretroviral therapy (ART) on psychosocial outcomes and physical activity among HIV-positive children in Botswana. METHOD: 201 HIV-positive children (6-15 years; M = 9.44, SD = 2.40) were recruited and randomly assigned (stratified by age and gender) to two groups. The intervention group (n = 97) received a high protein (bean-sorghum plus micronutrients) food supplement, while the control group (n = 104) received a sorghum plus micronutrients supplement. Participants were followed over 12 months. Anthropometric measures, PA, motor performance, and health related quality of life (HRQL) were collected at baseline, 6 and 12 months. RESULTS: Mixed repeated-measures ANOVA revealed a significant time effect of the food supplement on target variables except body fat percentage, speed, and school functioning. Time × treatment interaction was found for physical functioning, psychosocial functioning and total quality of life score. Scores on physical functioning and total of quality life in the intervention group significantly increased from baseline to 6 months compared with the control group (p = 0.015). CONCLUSION: A combination of ART and nutritional intervention had a positive effect on physical functioning and total quality of life of HIV-positive children in this study. There were also improvements to physical activity and motor performance tests over time. More research is needed on long term effects of nutrition and PA interventions on HRQL in children living with HIV.
