Non-response bias in estimates of prevalence of club-based sport participation from an Australian national physical activity, recreation and sport survey

Evaluation of a Workplace Active Rest Program in Office Workers With Comparison of a Prospective and Retrospective Survey

Physical activity-related workplace interventions can be counterstrategies for physical inactivity due to office work. Newly introduced programs should be evaluated for success. This study aimed to evaluate the intervention of a workplace active rest program and to compare a prospective and retrospective design of evaluation. A Germany-wide multicenter evaluation of a 3-month workplace active rest program (30 min, once a week) was carried out at 14 locations with a longitudinal pre/post design by means of an anonymous questionnaire (npre = 405, npost = 369). The participants' program-related changes in targeted characteristics regarding posture, function, complaints and physical awareness were collected with a questionnaire in a prospective design and afterward retrospectively. The prospective evaluation showed a significant improvement in the target characteristic "postural muscles in the neck area". In the retrospective survey, all target characteristics improved significantly. There were no differences between locations. The workplace active rest program in this study had positive effects on the perception of postural neck muscle status regardless of prospective or retrospective approach. Selection of survey mode should depend on desired outcome and consecutive influencing factors. In this specific case, retrospective survey could give more indirect information about overall satisfaction with the program and job although being influenced by response bias. Recall bias should be relatively small for shorter time periods assessed. Future studies should account for corresponding bias and specifics of target characteristics regardless of the chosen approach to survey.

Gender inclusive sporting environments: the proportion of women in non-player roles over recent years

Background

Throughout the ecosystem of sport, women have been and continue to be underrepresented at all levels compared to men. The capacity of community-level sport is heavily reliant on the many non-player roles including governance, as well as administration, coaching and officiating. Recently there has been increased attention to improving the gender balance in sport. The aim of this study is to investigate the proportions of women engaged in non-playing roles in sport (2016–2018).

Methods

This study involved secondary analysis of the AusPlay survey, a national population survey, funded by Sport Australia. This study utilised data from people aged 15-years or older about their involvement in non-playing roles in sport, and their demographic data. Survey respondents were asked “During the last 12 months, have you been involved with any sports in a nonplaying role, such as official, coach, referee, administrator, etc?” Analysis of non-player role responses focussed specifically on the top four non-player role categories; coach, official, administrator and manager. Frequency analysis concentrated on the distribution of men and women involvement in a non-player capacity for the three years, with detailed analysis of the most recent year (2018).

Results

In this study of 61,578 Australians there was a higher proportion of men in non-player roles in sport compared to women, across each of the three years (2018: men 55 %, women 46 %). Involvement of women in coaching increased significantly from 38 % to 2016 to 44 % in 2018 (p < 0.001). The proportion of women involved in administration roles significantly decreased from a peak of 51 % in 2017 to 46 % in 2018 (p < 0.001).

Conclusions

Aligned with strategic policy and investment strategies, there are gradual increased representation of women in non-playing sport, coaching roles. Women are still underrepresented in terms of coaches, officials and administrators, but are more likely to be managers. It is recommended that there is continued mentoring, identification and emphasising of female role models, and further strategies to increase female presence in non-playing roles. We recommend that future research, in line with appropriate gender and cultural-change theories, investigates and discusses the progress of gender equality throughout playing and non-playing role in sport.

A framework for exploring non-response patterns over time in health surveys

Background

Most health surveys have experienced a decline in response rates. A structured approach to evaluate whether a decreasing - and potentially more selective - response over time biased estimated trends in health behaviours is lacking. We developed a framework to explore the role of differential non-response over time. This framework was applied to a repeated cross-sectional survey in which the response rate gradually declined.

Methods

We used data from a survey conducted biannually between 1995 and 2017 in the city of Rotterdam, The Netherlands. Information on the sociodemographic determinants of age, sex, and ethnicity was available for respondents and non-respondents. The main outcome measures of prevalence of sport participation and watching TV were only available for respondents. The framework consisted of four steps: 1) investigating the sociodemographic determinants of responding to the survey and the difference in response over time between sociodemographic groups; 2) estimating variation in health behaviour over time; 3) comparing weighted and unweighted prevalence estimates of health behaviour over time; and 4) comparing associations between sociodemographic determinants and health behaviour over time.

Results

The overall response rate per survey declined from 47% in 1995 to 15% in 2017. The probability of responding was higher among older people, females, and those with a Western background. The response rate declined in all subgroups, and a faster decline was observed among younger persons and those with a non-Western ethnicity as compared to older persons and those with a Western ethnicity. Variation in health behaviours remained constant. Prevalence estimates and associations did not follow the changes in response over time. On the contrary, the difference in probability of participating in sport gradually decreased between males and females, while no differential change in the response rate was observed.

Conclusions

Providing insights on non-response patterns over time is essential to understand whether declines in response rates may have influenced estimated trends in health behaviours. The framework outlined in this study can be used for this purpose. In our example, in spite of a major decline in response rate, there was no evidence that the risk of non-response bias increased over time.

Sport participation settings: where and 'how' do Australians play sport?

Background

Leisure-time physical activity and sport participation trends are often reported, both in aggregate and by specific activity. Recently there has been a rise in overall leisure-time physical activity, but little change in the prevalence of organised sport. It is important that the development of sport policy, infrastructure and strategic developments meet the changing landscape of participation. However, there has been relatively little research into the settings in which people participate. The aim of this study is to investigate the settings of participation of children and adults in 12 major Australian sports.

Methods

This study utilised data about participation in sport and recreational physical activity collected in the AusPlay survey from a representative sample of adults and children in the Australian state of Victoria. For each type of physical activity, the settings of participation are identified. Respondents can report participation in a particular activity in more than one setting. Therefore we use the term “instance of participation” to refer to a person playing a particular sport in a particular setting. Participation and settings across 12 major sports were investigated for children and adults.

Results

For children, the most popular sport was swimming with a weighted estimate of 323,565 (30.3%) instances of participation in the Victorian population, followed by Australian football (n = 180,459; 16.9%), and basketball (n = 137,169; 12.9%). For adults the most popular sports were swimming (n = 703,950; 30.9%) followed by golf (n = 274,729; 12.1%), and tennis (n = 260,814; 11.4%). There were considerable differences between the profiles of settings of participation for the 12 sports. Across the 12 sports, the majority of participation by children took place within a sports club or association setting, representing 63% of all instances of sport participation. For adults, sports clubs and associations was also the most popular setting, but it represented only 37% of instances of participation.

Conclusions

Traditionally, community clubs and inter-club competitions provided the main setting for sport participation, but this is no longer the case, particularly for adults. If the community sport sector is to continue to flourish, it must consider new strategies and participation options more attractive to other segments of its potential market.
