ABSTRACT
BACKGROUND: Regular physical activity (PA) has documented effects in prevention and treatment of many non-communicable diseases (NCDs). Physical inactivity is recognized as the fourth leading risk factor for premature death, worldwide. Despite these facts, physical inactivity is increasing, not only in high-income, but also in middle- and low-income countries. To address this negative trend, evidence-based methods to increase PA are needed. The purpose of this paper is to describe the implementation and assessment of 4 strategies designed to increase PA in Vietnam. METHODS: Four strategies were used: i) introduction and evaluation of an education and training program on the Swedish method of Physical Activity on Prescription (PAP) among health care professionals, ii) translation of the PAP evidence-based handbook, Physical Activity in the Prevention and Treatment of Disease (called FYSS in Swedish) into Vietnamese, iii) launch of a mass-media campaign to promote PA, and iv) advocacy to support development of PA guidelines in Vietnam. RESULTS: The evaluation indicated that the participating health care professionals had a positive attitude to PAP. However, they also reported uncertainty in prescribing PA. FYSS was translated and disseminated successfully to health care professionals. A mass-media campaign identified the beneficial effects of PA to health care professionals, journalists, policy makers, and the public. Last, the process of developing national guidelines on PA was initiated. CONCLUSION: This project led to enhanced awareness and appreciation of PA in the prevention and treatment of NCDs among health care professionals as well as initiation of national PA guidelines. Important lessons also were learned in the presentation of PAP, which will be considered when designing similar projects in the future.
ABSTRACT
AIM: Socio-economic status is an important determinant of physical activity, sedentary behaviour and body mass index, but these associations are contradictory in younger children. We investigated the associations between parental socio-economic status, physical activity, sedentary behaviour and body mass index in six-year-old children, to identify possible differences in physical activity between socio-economic groups. METHODS: The study comprised 621 children from Stockholm suburbs, recruited from, A healthy school start, a cluster-randomised controlled intervention study. A cross-sectional study was performed using baseline data. Physical activity and sedentary behaviour were assessed by accelerometry, body weight and height were measured, and body mass index was calculated. Sedentary behaviour was also assessed using a questionnaire. RESULTS: We found that 12% of the study population were overweight and 9% were obese. Children from families with low socio-economic status were more physically active and slightly less sedentary, but were almost twice as likely to be overweight or obese than children from high socio-economic status, irrespective of the child's sex. CONCLUSION: Low socio-economic status was associated with higher physical activity, lower sedentary behaviour and an unhealthier weight status compared to high socio-economic status, suggesting a role of diet as a cause of the higher overweight and obesity prevalence.
