This study is part of a broader program of research in Australia which involves the longitudinal measurement of sport and physical activity profiles and physical, mental and social health and wellbeing outcomes that are the result of this participation. This study was conducted in two waves of online surveying during the COVID-19 period (2020 and 2021). The first wave of data collection included retrospective (baseline) data pertaining to pre-COVID-19 participation rates in 2019.
Full details of the program of research can be found elsewhere (2, 9). Briefly, recruitment to the survey was primarily facilitated by several national and state sporting organizations. The target population was people aged 13 years or older who were registered in the 2019 and/or 2020 playing seasons to participate in one or more sports. The sport organizations that sent out the survey invitation to their registered participants represent major sports in Victoria and Australia (26, 27).
The first wave of the longitudinal survey (conducted May-June 2020) included among other themes, questions about:
-
Demographic characteristics – gender, age, and residential postcode
-
Types of sports and other recreational physical activities participated in
-
Frequency and duration of participation, at the time of the survey and during the previous year.
Date of birth was used to determine age in years at the time the survey was completed. Age was then recoded into two age cohorts: adolescents (13–17 years) and adults (18 years and above). Residential postcode correspondence tables (28) were used to assign each postcode to one of two broad geographical zones or regions: Metropolitan, comprising the capital cities of the Australian states; and Non-metropolitan, comprising regional cities, towns and rural areas.
All participants in the first survey were invited to participate in a similar follow-up survey conducted one year later, in May-June 2022, and just over 20% did so. The study is based on the group of adult respondents to both surveys.
Regarding recreational physical activity (RPA), two separate sections of the survey dealt respectively with two ‘settings’: organised club sport involving membership and registration (designated ‘Club sport’), and less structured sport and recreational physical activity (designated ‘Other RPA’). In each section, a list of the most common activities was presented – 16 for club sport and 26 for other RPA (which also included 12 of the 16 club sports). Respondents indicated the activities in which they participated, with provision for adding other activities that were not listed.
Because organized club sport was heavily impacted by COVID-19 restrictions in 2020 and their subsequent easing in 2021, the present study was focused on club sport participation. Each respondent was assigned, for each of the three epochs (designated 2019, 2020, 2021) a dichotomous club sport participation indicator (1 = participated, 0 = did not participate). This set of three indicators provides a ‘broad brush’ snapshot of the overall impact of the imposition of COVID-19 restrictions in 2020 and their subsequent easing in 2021 on levels of engagement in club sport.
The three dichotomous indicators together define a pattern or sequence of participation over the 3-year period. There are eight (2×2×2) possible sequences, of which four involve no participation in 2019. These four patterns were driven by various individual factors rather than COVID-19 restrictions, and each had low counts in some demographic categories, and so participants with these patterns were excluded, reducing the number of patterns to four. The small group of respondents who dropped out of club sport only in the final year of the study (2021) were also excluded because this participation pattern was not related to COVID-19 restrictions per se. Hence the three groups whose 2021 health assessments were compared were designated as follows:
-
Dropped out: played in 2019 and did not play in 2020 or 2021
-
Dropped out and returned: played in 2019 and 2021 and did not play in 2020
-
Continued: played in 2019, 2020 and 2021
The first two of these three 2021 groups constituted a single group in 2020, and only split into two groups in 2021. Hence, the comparisons of 2020 health assessments were made between two groups, designated as follows:
Three survey items were devoted to self-assessed health. The general health item was a 5-point Likert scale item (poor, fair, good, very good, excellent) derived from the Short-form Health Survey (SF-36) instrument (29). The same format was used for the assessment of physical health and mental health.
Statistical analysis
Responses to the three health items for each year (2020 and 2021) were cross-tabulated against the two (2020) or three (2021) patterns of participation. Chi-square tests of independence were conducted to identify differences in the health profiles of the groups defined by the two/three patterns of participation. These analyses were conducted for the survey sample as a whole, and also for subsamples based on gender, age cohort and region of residence. To ensure that sample sizes in all cells of the cross-tabulations were sufficient for valid and reliable inference, each of the 5-category health items were recoded into three categories (poor/fair, good, very good/excellent). Data analysis was conducted using SPSS Version 27, with statistical significance defined as p < .05.
