Performance of the international physical activity questionnaire (short form) in subgroups of the Hong Kong chinese population.

ABSTRACT:

Background

The International Physical Activity Questionnaire (IPAQ-SF) has been validated and recommended as an efficient method to assess physical activity, but its validity has not been investigated in different population subgroups. We examined variations in IPAQ validity in the Hong Kong Chinese population by six factors: sex, age, job status, educational level, body mass index (BMI), and visceral fat level (VFL).

Methods

A total of 1,270 adults (aged 42.9 ± SD 14.4 years, 46.1% male) completed the Chinese version of IPAQ (IPAQ-C) and wore an accelerometer (ActiGraph) for four days afterwards. The IPAQ-C and the ActiGraph were compared in terms of estimated Metabolic Equivalent Task minutes per week (MET-min/wk), minutes spent in activity of moderate or vigorous intensity (MVPA), and agreement in the classification of physical activity.

Results

The overall Spearman correlation (?) of between the IPAQ-C and ActiGraph was low (0.11 ± 0.03; range in subgroups 0.06-0.24) and was the highest among high VFL participants (0.24 ± 0.05). Difference between self-reported and ActiGraph-derived MET-min/wk (overall 2966 ± 140) was the smallest among participants with tertiary education (1804 ± 208). When physical activity was categorized into over or under 150 min/wk, overall agreement between self-report and accelerometer was 81.3% (± 1.1%; subgroup range: 77.2%-91.4%); agreement was the highest among those who were employed full-time in physically demanding jobs (91.4% ± 2.7%).

Conclusions

Sex, age, job status, educational level, and obesity were found to influence the criterion validity of IPAQ-C, yet none of the subgroups showed good validity (? = 0.06 to 0.24). IPAQ-SF validity is questionable in our Chinese population.

Project description:BackgroundThe Physical Activity and Sedentary Behaviour Assessment Questionnaire (PASBAQ), used within the Health Survey for England (HSE) at 5-yearly intervals, is not included annually due to funding and interview-length constraints. Policy-makers and data-users are keen to consider shorter instruments such as the Short-form International Physical Activity Questionnaire (IPAQ) for the annual survey. Both questionnaires were administered in HSE 2012, enabling comparative assessment in a random sample of 1252 adults.MethodsRelative agreement using prevalence-adjusted bias-adjusted Kappa (PABAK) statistics was estimated for: sufficient aerobic activity (moderate-to-vigorous physical activity [MVPA] ≥150 minutes/week); inactivity (MVPA<30 minutes/week); and excessive sitting (≥540 minutes/weekday). Cross-sectional associations with health outcomes were compared across tertiles of MVPA and tertiles of sitting time using logistic regression with tests for linear trend.ResultsCompared with PASBAQ data, IPAQ-assessed estimates of sufficient aerobic activity and inactivity were higher and lower, respectively; estimates of excessive sitting were higher. Demographic patterns in prevalence were similar. Agreement using PABAK statistics was fair-to-moderate for sufficient aerobic activity (0.32-0.49), moderate-to-substantial for inactivity (0.42-0.74), and moderate-to-substantial for excessive sitting (0.49-0.75). As with the PASBAQ, IPAQ-assessed MVPA and sitting each showed graded associations with mental well-being (women: P for trend = 0.003 and 0.004, respectively) and obesity (women: P for trend = 0.007 and 0.014, respectively).ConclusionsCapturing habitual physical activity and sedentary behaviour through brief questionnaires is complex. Differences in prevalence estimates can reflect differences in questionnaire structure and content rather than differences in reported behaviour. Treating all IPAQ-assessed walking as moderate-intensity contributed to the differences in prevalence estimates. PASBAQ data will be used for population surveillance every 4 to 5 years. The current version of the Short-form IPAQ was included in HSE 2013-14 to enable more frequent assessment of physical activity and sedentary behaviour; a modified version with different item-ordering and additional questions on walking-pace and effort was included in HSE 2015.

Project description:BACKGROUND:Fertility preservation for both medical and non-medical reasons are gaining increasing attention world-wide. This study aimed to evaluate the awareness, knowledge and acceptance on fertility preservation in Hong Kong Chinese. METHODS:This was a cross-sectional study carried out between June 2016 to March 2017. A self-administered questionnaire was distributed by convenience sampling. RESULTS:Forty two percent of subjects returned the questionnaire (n?=?296/697). Among them, only 54.3% were aware of any means of fertility preservation. Tertiary educated individuals are more aware than less educated individuals (73.6% versus 46.6%, p?<?0.001). The most commonly known method is oocyte cryopreservation (94.3%). Most of the respondents (80%) were interested to know about fertility preservation, 84.1% considered fertility preservation counselling necessary and 83.3% would consider undergoing fertility preservation if a treatment has a high chance of causing infertility despite the possibility of delay in cancer treatment. Up to 93.9% agreed to set up a dedicated referral centre with government funding and 73.4% agreed that fertility preservation for medical indication should be provided as a government funded service. In terms of fertility preservation for non-medical reason, 65.5 and 70.4% agreed that fertility preservation should be offered to single men and women without partner respectively, while only 53.3 and 50% agreed that fertility preservation is acceptable for delay in childbearing for career development in female and male respectively. CONCLUSION:There was a low awareness but positive attitude towards fertility preservation among Hong Kong Chinese. Acceptance towards medically indicated fertility preservation is high while a considerable number also accepts it for non-medical reasons. Educational campaigns are required to arouse awareness of fertility preservation to prevent individuals being deprived of the option due to lack of knowledge. Dedicated referral centre with established efficient patient referral pathways and financial support should be provided to improve the provision and uptake of fertility preservation service to enhance the reproductive potential and life options of women.
