Project description:Background:Regular exercise training stimulates physiological adaptations to improve physical performance, reduce chronic disease risk, and slow age-related cognitive decline. Since the physiological mechanisms responsible for aging-associated cognitive decline are not yet fully understood, and training-induced physiological adaptations responsible for performance measure improvements are specific to the type (aerobic vs. strength) and intensity of training, studies are needed to assess the relationships between physical performance measures and cognitive performance in older adults. These results could be used to guide exercise prescriptions with the goal of improving age-related cognitive performance. The purpose of this study was to investigate the relationship between physical performance measures and cognitive performance in a population of community dwelling, ethnically diverse older adults. Methods:The cognitive performance of ninety independent, community dwelling participants (69 female, 21 male), aged 75 ± 9.5 years (mean ± SD) was measured with the Modified Mini-Mental State Test (3MS), Trailmaking Tests A and B (TMT A & B), and the Animal Naming test. Sociodemographic (age, sex, ethnicity, medication use, years of education) and anthropometric data were collected, physical activity was assessed with the Physical Activity Scale for the Elderly (PASE), peak hand-grip strength, distance walked in the 6MWT, and heart rate pre-, during, and up to 5 min. post- 6MWT were measured. Forward stepwise multiple regression analyses were performed with each cognitive measure as a dependent variable. Results and Discussion:Controlling for sociodemographic covariates, peak heart rate during the 6MWT (6MWT HRPEAK) was positively correlated with performance in the 3MS (p < 0.017), and TMT A (p < 0.001) and B (p < 0.029). Controlling for sociodemographic covariates, PASE was positively (p = 0.001), and ?-blocker use negatively (p = 0.035), correlated with performance on the Animal Naming test. Also, controlling for sociodemographic covariates, PASE was positively correlated with performance on the TMT A (p = 0.017). Here we show that higher peak heart rate during the 6MWT is positively correlated with cognitive performance in a population of community dwelling, ethnically diverse older adults (ages 60-95 years). Conclusion:Higher peak heart rate during the 6MWT was found to be independently and positively correlated with cognitive function in community-dwelling older adults. Although additional work is needed, these results are promising and suggest that physicians, exercise professionals, and/or fitness/fall prevention programs may use peak heart rate during the 6MWT to easily monitor exercise intensity to support cognitive health.

Project description:BackgroundThere are limited longitudinal data regarding nutrient intake, nutritional status and physical function in community-dwelling ethnically diverse older adults. This study explored these variables and their relationship at baseline (n = 100) and 8-months' follow-up (n = 81) among community-dwelling ethnically diverse older adults (≥60 years) in Birmingham, United Kingdom.MethodsMultiple-pass 24-h dietary recalls and the Mini Nutritional Assessment-Short Form assessed nutritional intake and status, respectively. Short Physical Performance Battery (SPPB) and handgrip strength measured physical function. Linear and multinomial regressions were used to predict relationships between physical function, nutritional status and nutrient intake.ResultsComplete data were collected at baseline (n = 100) and 8-months' follow-up (n = 81). Mean (SD) age was 70 (8.1) years (60% male), with 62% being obese. Statistically significant decreases in intakes of vitamin B6, vitamin B1, iron, folate, and magnesium occurred over time. Daily intake of all micronutrients except vitamin B12, phosphorus and manganese were below the Recommended Nutrient Intakes (RNI). SPPB (Z = -4.01, p < 0.001) and nutritional status (Z = -2.37, p = 0.018) declined over time. Higher SPPB scores at baseline (OR = 0.54 95% CI 0.35, 0.81) were associated with a slower decline in nutritional status.ConclusionThe observed declines and inadequate nutrient intakes in the absence of weight loss in just 8 months may pose serious challenges to healthy ageing, identifying an urgent need to re-evaluate and tailor appropriate dietary advice for this population. Additionally, the associations of nutrition and physical function observed in this study serves as an essential resource to design and implement community/faith-based interventions targeting early screening of nutritional status and physical function to ensure most older adults are assessed and treated accordingly.

Project description:BackgroundThe United Kingdom population is ageing and becoming increasingly diverse; thus, it is vital to develop and implement interventions supporting this population shift. Social networks (SN) significantly impact health outcomes in later life, however relatively little is known about SN of community-dwelling ethnically diverse older adults. This study aimed to: 1) profile SN and changes in SN in this population over 8 months; 2) examine associations between SN, dietary intake, nutritional status, and physical function.MethodsSN were assessed using the Wenger Practitioner Assessment of Network Type. Energy and nutrient intakes were measured using multiple-pass 24-h recalls. The Mini Nutritional Assessment-Short Form (MNA-SF) assessed nutritional status. Physical function was measured using the Short Physical Performance Battery (SPPB) and handgrip strength. Data were collected at baseline and 8-months. Correlation and regression analyses examined relationships between SN, physical function, nutrient intake and nutritional status. Semi-structured interviews were conducted at baseline (n = 92) and follow-up (n = 81) to identify potential influences of SN. Interviews were transcribed verbatim and analysed using directed content analysis.ResultsQuantitative data were obtained from 100 participants at baseline and 81 at follow-up. Mean (SD) age was 70.8 (8.1) years (59% male), comprising African/Caribbean (60%), South Asian (34%), and other ethnicities (6%). Five SN typologies were identified under two broad areas: integrated-SN consisting of locally integrated (44%) and wider community (8%); and non-integrated-SN consisting of family dependent (25%), local self-contained (17%), and private restricted (6%). At follow-up, 37% remained in non-integrated networks, 19% transitioned to non-integrated networks, 11% transitioned to, and 33% remained in, integrated networks. Participants within integrated networks at baseline had higher SPPB scores at follow-up. Compared to the private restricted, local self-contained SN significantly predicted zinc, riboflavin and vitamin B6 intakes. Participants remaining in, or transitioning to, non-integrated networks had low MNA-SF scores. Qualitative findings indicate that participants with reductions in SN perceived it as causing poorer physical function and eating behaviours.ConclusionIn the present study, integrated SN were associated with higher physical function and nutritional status at 8-month's follow-up. These results can inform the design of interventions to improve social networks, physical function and healthy nutrition within this population.

Project description:ObjectiveThe public health message 'move for health' is relevant given the high prevalence of insufficient physical activity, particularly in African countries. The call for behaviour modification including limiting unhealthy dietary patterns in these settings is therefore critical; however, there is limited knowledge on the adoption of health promotion strategies in the workplace. This study aimed to investigate workers' perceptions of physical activity and healthy eating.ResultsFive focus groups were conducted with 28 participants employed in a South African pharmaceutical manufacturing company to explore perceptions of physical activity and healthy eating. Results showed that two categories emerged: physical activity and unhealthy behaviours. Participants recognised the importance of obtaining sufficient physical activity in various domains, however believed that contemporary lifestyle limited opportunities for movement. Likewise, participants viewed healthy eating as unrealistic due to financial constraints. There was however agreement that total physical activity time could be increased during recreational pursuits outside of vocational time and may include intermittent walking for travel. These findings are important for workplace interventions and provide a more robust understanding of workers' perceptions of physical activity and healthy eating.

Project description:BackgroundEating behaviours in childhood are considered as risk factors for eating disorder behaviours and diagnoses in adolescence. However, few longitudinal studies have examined this association.AimsWe investigated associations between childhood eating behaviours during the first ten years of life and eating disorder behaviours (binge eating, purging, fasting and excessive exercise) and diagnoses (anorexia nervosa, binge eating disorder, purging disorder and bulimia nervosa) at 16 years.MethodData on 4760 participants from the Avon Longitudinal Study of Parents and Children were included. Longitudinal trajectories of parent-rated childhood eating behaviours (8 time points, 1.3-9 years) were derived by latent class growth analyses. Eating disorder diagnoses were derived from self-reported, parent-reported and objectively measured anthropometric data at age 16 years. We estimated associations between childhood eating behaviours and eating disorder behaviours and diagnoses, using multivariable logistic regression models.ResultsChildhood overeating was associated with increased risk of adolescent binge eating (risk difference, 7%; 95% CI 2 to 12) and binge eating disorder (risk difference, 1%; 95% CI 0.2 to 3). Persistent undereating was associated with higher anorexia nervosa risk in adolescent girls only (risk difference, 6%; 95% CI, 0 to 12). Persistent fussy eating was associated with greater anorexia nervosa risk (risk difference, 2%; 95% CI 0 to 4).ConclusionsOur results suggest continuities of eating behaviours into eating disorders from early life to adolescence. It remains to be determined whether childhood eating behaviours are an early manifestation of a specific phenotype or whether the mechanisms underlying this continuity are more complex. Findings have the potential to inform preventative strategies for eating disorders.

Project description:There has been little investigation of gene-by-environment interactions related to sedentary behaviour, a risk factor for obesity defined as leisure screen time (ST; i.e. television, video and computer games).To test the hypothesis that limiting ST use attenuates the genetic predisposition to increased body mass index (BMI), independent of physical activity.Using 7642 wave II participants of the National Longitudinal Study of Adolescent Health, (Add Health; mean?=?16.4 years, 52.6% female), we assessed the interaction of ST (h?week(-1) ) and 41 established obesity single nucleotide polymorphisms (SNPs) with age- and sex-specific BMI Z-scores in 4788 European-American (EA), 1612 African-American (AA) and 1242 Hispanic American (HA) adolescents.Nominally significant SNP*ST interaction were found for FLJ35779 in EA, GNPDA2 in AA and none in HA (EA: beta [SE]?=?0.016[0.007]), AA: beta [SE]?=?0.016[0.011]) per 7?h?week(-1) ST and one risk allele in relation to BMI Z-score.While for two established BMI loci, we find evidence that high levels of ST exacerbate the influence of obesity susceptibility variants on body mass; overall, we do not find strong evidence for interactions between the majority of established obesity loci. However, future studies with larger sample sizes, or that may build on our current study and the growing published literature, are clearly warranted.

Project description:ObjectiveTo examine differences in eating and physical activity behaviours among ethnic groups in Queensland, Australia, and differences in those behaviours due to the duration of residency in Australia.DesignCross-sectional study using baseline data collected for the Living Well Multicultural-Lifestyle Modification Program between October 2014 and June 2017.SettingCulturally and linguistically diverse communities (CALD), including Afghani, Somali, Burmese, Pacific and South Sea Islander, Sri Lankan, Sudanese and Vietnamese, living in Queensland, Australia.ParticipantsPeople were recruited if they were ≥18 years old and living in the targeted CALD communities.ResultsBurmese/Vietnamese, on average, had better eating scores in line with Australian dietary guidelines, compared with Afghani/Arabic-speaking (difference = 2·05 points, 95 % CI 1·39, 2·72), Somali/Sudanese (difference = 1·53 points, 95 % CI 0·79, 2·28) and Pacific Islander (difference = 1·46 points, 95 % CI 0·79, 2·13). Association between ethnicity and meeting the physical activity guideline was not significant. Those who stayed in Australia longer than a year were less likely to meet the physical activity guideline than those staying <1 year (OR = 0·51, 95 % CI 0·31, 0·84). There was no significant association between duration of residency in Australia and eating scores.ConclusionsEating behaviours were significantly different among the ethnic groups in Queensland with Burmese/Vietnamese and Sri Lankan/Bhutanese having the healthiest diets. All ethnic groups were less likely to meet the physical activity guideline compared with the general Australian population. People with duration of residency of at least 1 year in Australia were less likely to meet the physical activity guideline compared with those who had shorter stays.

Project description:BackgroundConflicting breast cancer screening recommendations have the potential to diminish informed decision making about screening.ObjectiveWe examined the knowledge, attitudes, and intentions related to divergent recommendations for breast cancer screening among racially/ethnically diverse women.DesignWe used a multimethod study design employing focus groups and questionnaires. Focus groups included: (1) two 10-min presentations on the national screening recommendations and the potential benefits and harms of screening and (2) an interactive discussion. Data were collected: 8/3/2017 to 11/19/2019. Analysis occurred from 1/21/2019 to 7/24/2020.ParticipantsParticipants were (1) women 40-75 years; (2) English or Spanish speaking; (3)self-identified as Latina, Black, or non-Latina White; and (4) no known increased risk for breast cancer.Main measuresMain outcomes were participants' knowledge and perceptions of benefits and harms of screening mammography and their screening intentions. Focus groups were transcribed and analyzed using a qualitative descriptive approach. Quantitative data were summarized using descriptive statistics.Key resultsOne hundred thirty-four women (n=52, 40-49 years; n=82, 50-75 years) participated in 28 focus groups. Participants were Latina (n=44); Black (n=51); and non-Latina White (n=39). Approximately one-quarter (n=32) had limited health literacy and almost one-fifth (n=23) had limited numeracy. In the context of differing national screening recommendations, participants questioned the motives of the recommendation-making agencies, including the role of costs and how costs were considered when making screening recommendations. Participants expressed concern that they were not represented (e.g., race/ethnicity) in the data informing the recommendations. Immediately following the focus groups, most participants expressed intention to screen within the upcoming year (pre n=100 vs. post n=107).ConclusionsDivergent breast cancer screening recommendations may lead to mistrust and paradoxically reinforce high overall enthusiasm for screening.

Project description:ObjectiveTo conduct formative research using qualitative methods among stakeholders of secondary schools to explore their perceptions, barriers and facilitators related to healthy eating and physical activity (PA) among Malaysian adolescents.DesignA qualitative study involving eight focus groups and twelve in-depth interviews. Focus groups and interviews were recorded and transcribed verbatim. An inductive thematic analysis approach was used to analyse the data.SettingFour secondary schools in Perak and Selangor states (two urban and two rural schools) in Malaysia.ParticipantsFocus groups were conducted with seventy-six adolescents aged 13-14 years, and in-depth interviews were conducted with four headmasters, four PA education teachers and four food canteen operators.ResultsStakeholders thought that adolescents' misperceptions, limited availability of healthy options, unhealthy food preferences and affordability were important challenges preventing healthy eating at school. Low-quality physical education (PE) classes, limited adolescent participation and teachers' commitment during lessons were perceived as barriers to adolescents being active at school. Affordability was the main challenge for adolescents from rural schools. Stakeholders perceived that a future school-based intervention should improve the availability and subsidies for healthy foods, provide health education/training for both adolescents and PE teachers, enhance active adolescent participation in PE and develop social support mechanisms to facilitate engagement with PA.ConclusionsThese findings provide important insights into developing school-based lifestyle interventions to improve healthy eating and strengthening PA of Malaysian adolescents.

Project description:Background Diet and fitness apps are often promoted in university and college settings and touted as a means to improve health with little attention given to unanticipated negative effects, especially among those at risk for or with eating disorders. Aims Few researchers have studied how these apps affect women with eating disorders in university and college settings. This research investigates the unintended negative consequences of engaging with these tools. Method Data collection sessions comprised three components conducted with 24 participants: survey (demographic and eating disorder symptoms), think-aloud exercise and semi-structured interview. Thematic analysis was used to analyse data. Results Participants reported that diet and fitness apps trigger and exacerbate symptoms by focusing heavily on quantification, promoting overuse and providing certain types of feedback. Eight themes of negative consequences emerged: fixation on numbers, rigid diet, obsession, app dependency, high sense of achievement, extreme negative emotions, motivation from ‘negative’ messages, and excess competition. Although these themes were common when users’ focus was to lose weight or eat less, they were also prevalent when users wanted to focus explicitly on eating disorder recovery. Conclusions Unintended negative consequences are linked to the quantified self movement, conception of appropriate usage, and visual cues and feedback. This paper critically examines diet and fitness app design and discusses implications for designers, educators and clinicians. Ultimately, this research emphasises the need for a fundamental shift in how diet and fitness apps promote health, with mental health at the forefront.
