    Physical activity and sedentary time distribution among adult residents during COVID-19 circuit breaker movement restrictions in Singapore: A public health perspective
    (Wolters Kluwer, 2023) ;
    Tan, Kang Jin

    Introduction:
    Social lockdowns and quarantines have been enforced in various populations to mitigate the spread of coronavirus disease 2019 (COVID-19) in the community. This study investigated the impact of COVID-19 lockdown, known as circuit breaker movement restrictions (CBMR), on physical activity (PA) and sedentary time (ST) distribution patterns among Singapore residents aged 21–65 years.
    Methods:
    This was a cross-sectional retrospective study that utilised a 44-item questionnaire that included sections to determine PA and ST distribution patterns before and during CBMR. It also included information on sleep duration, PA preference and routine, awareness of local initiatives and perceptions on barriers towards PA during the CBMR period.
    Results:
    There was an overall decrease in PA and a significant increase in physical inactivity and ST during the CBMR period. A greater proportion of participants reported sleeping for longer hours, suggesting positive adaptations in sleep habits during CBMR. Majority were unaware of online exercise initiatives and programmes offered during the CBMR period, and >50% of the respondents never used an online resource for exercise. Singapore residents seemed to prefer outdoor and facility-based venues for exercise and PA, and closure of facilities was the primary barrier for PA during the CBMR period.
    Conclusion:
    Reduced PA and increased ST during CBMR reflect negative lifestyle adaptations and may have adverse public health implications. Increased sleep duration suggests successful coping, which may consequently lead to physical and mental health benefits. While Singapore adult residents may be flexible with certain aspects of being physically active, they seemed less adaptive to changes in type of exercise, facility and environment.

    Traumatic upper limb injuries during the men’s Field Hockey Junior World Cup 2009
    (Taylor & Francis, 2013)
    This study was a prospective epidemiological investigation of upper limb injuries during the Men’s Field Hockey Junior World Cup 2009. 324 players were observed in 58 matches of the tournament. 28 upper limb-related injuries were documented. The injury incidence was 0.48 per match and 19 per 1000 match hours. Most injuries were due to contact with the ball and left hand was the most commonly injured part. Contusion was the commonest type of injury. The odds ratio for hand and wrist injuries in players not wearing gloves was 4.01(95% CI, 0.52-30.62) and the relative risk of hand and wrist injuries in players wearing gloves was 0.26 (95% CI, 0.03-1.92). Male youth hockey players are at a high risk of upper limb especially hand and wrist injuries during major international tournaments and that use of protective gloves can provide significant protection against hand and wrist injuries in the sport.

    Inactivity physiology: The anthropometric and blood parameters of Singaporean youths
    (2013) ; ;
    Lye, Jamie Ching Ting
    The anthropometric and blood parameters of 229 Singaporean adolescent youths, aged 13–15 recruited from seven secondary schools, were examined. Out of these youths, 71.5% were of healthy weight, 14.7% were underweight, 8.9% were overweight and 4.9% were obese, based on the BMI-for-age for adolescents set by the Ministry of Education. Health measurements like waist circumference, resting blood pressure and blood parameters—triglycerides, high-density lipoprotein, blood glucose derived from a fasted state, and insulin resistance—were obtained in accordance to standard international protocols. Clustered metabolic risk was used to quantify participants who were at significant risk of metabolic syndrome. Twenty-seven or 11.8% were identified as at-risk of metabolic syndrome CMR was significantly associated with body mass, waist circumference, resting systolic and diastolic blood pressure, fasted blood triglyceride, and fasted blood glucose. CMR was also moderately associated with IR. Waist circumference, percentage of body fat, and blood triglycerides and resting blood pressure were significantly correlated with IR. From the study, it was found that poor metabolic health is a concern among adolescent youths in Singapore, not only in those who were overweight or obese, but also in those who are of normal weight and underweight.

    Physical activity and sedentary behavior patterns of Singaporean adolescents
    (Human Kinetics, 2015)
    Lye, Jamie Ching Ting

    ;
    Background: Adolescents require at least 60 minutes of daily moderate to vigorous intensity physical activity (PA) for optimum health benefits. Reduced active and increased sedentary time can adversely affect health independently. This study investigated the sedentary behavior and physical activity patterns of Singaporean adolescents.
    Methods: 233 adolescents aged 13-15 years participated in the study. Accelerometery was used to assess the daily PA patterns for three weekdays and two weekend days consecutively. Height, weight, BMI, waist circumference and waist-hip ratio were determined as surrogate measures of health.
    Results: None of the participants achieved the recommended 60 minutes of daily MVPA on all five days. Significantly more time was spent engaging in sedentary activity compared to MVPA on both weekdays and weekends. MVPA and sedentary time were positively associated on weekdays after controlling for gender (p < .001). Weekday MVPA was positively associated with waist circumference (p < .001) and waist-hip ratio (p < .001).
    Conclusion: Singaporean adolescents fall substantially short of meeting the daily PA recommendations. Separate strategies to promote PA may be necessary for adolescents of differing weight status and gender. Pragmatic rather than idealistic targets to promote PA need to be set based on population-specific baseline data.

    This study aimed to examine prospective associations of mobile touch screen device (i.e. smartphone, tablet) use and patterns of use with musculoskeletal symptoms and visual health among adolescents. A representative sample of 1691 adolescents in Singapore (51% girls; 10–19 years) completed an online questionnaire at baseline and one-year follow-up. After adjusting for potential confounders, prospective associations were found between baseline smartphone use and follow-up neck/shoulder (OR = 1.61(95%CI = 1.06–2.44)) and low back (OR = 1.86(1.10–3.14)) symptoms; tablet use was also associated with neck/shoulder, low back and arms symptoms (OR = 1.33(1.04–1.71)to1.52(1.18–1.95)). No associations were observed between the duration of smartphone/tablet use and symptoms. Baseline patterns of use (bout length, certain types of activities, multitasking) were associated with follow-up musculoskeletal symptoms. Smartphone/tablet use was not related to visual outcomes (visual symptoms, wearing glasses/contact lenses, myopia) at follow-up. These findings suggest that patterns of smartphone/tablet use (though not the duration of use) can pose a prospective risk for musculoskeletal symptoms.

    Inactivity physiology: Staying still, Singaporean youths are not moving enough
    (2013) ; ;
    Lye, Jamie Ching Ting
    The physical inactivity of Singaporean youths was examined using state-of-the-art ambulatory motion sensors (Actitrainer triaxial accelerometers) under free-living conditions on 3 weekdays and 2 weekend days. Participants included 128 male and 116 female adolescents, aged 12–15, from seven secondary schools. Neither boys nor girls met the national and international recommendation to accumulate at least 60 mins of moderate-to-vigorous physical activity (MVPA) on a daily basis for healthy cardiovascular health. Sedentary time over the weekday and weekend accounted for a majority of the accelerometer-monitored time. Step count accumulated in school was 16% greater than outside-of-school time. Under free-living weekday and weekend living conditions, Singaporean youths are not sufficiently engaged in MVPA and if this behaviour becomes entrenched, it may have dire consequences on the future physical and metabolic health of adult Singaporeans.
