Behavioral impact of national health campaigns on healthy lifestyle practices among young adults in Singapore: a cross-sectional study

Background

National health campaigns are often used to improve lifestyle behaviors in the general population. However, evidence specifically in the young adult population is scarce. Given the general deterioration of healthy lifestyle practices from adolescence to young adulthood, it is imperative to study this age group. This study aimed to investigate the behavioral impact of a national health campaign in Singapore on the lifestyle practices of young adults, and whether sex or full-time working and schooling status affected lifestyle practices.

Methods

A total of 594 Singaporean respondents aged 18–39 years old were interviewed via a cross-sectional study in December 2019. Lifestyle practices assessed were diet, exercise, alcohol consumption, current tobacco use, and participation in health screening programs. Other factors investigated included exposure to the national health campaign “War on Diabetes” (WoD), sex, ethnicity, and working/schooling status. Multivariable modified Breslow-Cox proportional hazards models were used to estimate prevalence risk ratios (PRRs) as measures for the associations in this study, after adjusting for potential confounders.

Results

Exposure to the WoD campaign had a significant association with meeting dietary recommendations (PRR = 1.6, 95% CI: 1.0–2.5, p = 0.037), participation in screening (PRR = 1.2, 95% CI: 1.0–1.5, p = 0.028), and current tobacco use (PRR = 0.5, 95% CI: 0.3–0.8, p = 0.003). Males were significantly more likely to meet exercise recommendations (PRR = 2.0, 95% CI: 1.5–2.7, p < 0.001), currently use tobacco (PRR = 3.9, 95% CI: 2.2–6.9, p < 0.001), and consume alcohol excessively (PRR = 1.5, 95% CI: 1.0–2.3, p = 0.046), as compared to females. Working young adults were significantly less likely to meet exercise recommendations (PRR = 0.7, 95% CI: 0.5–0.9, p = 0.019) but significantly more likely to be current tobacco users (PRR = 1.8, 95% CI: 1.1–3.1, p = 0.024), as compared to those who were in school.

Conclusions

While this paper affirms that national health campaigns have significant beneficial associations in diet, health screenings and current tobacco use, policymakers should acknowledge that young adults are an age group with different influences that impact their healthy lifestyle habits. Specific interventions that target these subgroups may be required for better health outcomes. Future studies should evaluate other socio-environmental factors that could play a role in modifying the effect of health campaigns among young adults.

Strategic Priorities to Improve Effectiveness of Anti-smoking Interventions for the Korean Military: An Application of the Analytic Hierarchy Process

Introduction

As South Korea remains technically at war with the North, higher smoking prevalence in the military might adversely affect the South Korea's military power and contribute to lifetime smoking in men with mandatory military service. This study was to identify priorities among the anti-smoking strategies to improve the existing smoking cessation programs for the Korean military.

Methods

The analytic hierarchy process model with a goal, decision criteria, and sub-criteria as well as candidate strategies, was developed following a literature search and expert group discussion. A survey for pairwise comparison was conducted to determine the priority of the (sub-)criteria and strategies by 14 experts. The Super-Decisions software was used to determine the priorities and to analyze their consistency ratios and sensitivities. The study was approved by the ethics committee of the Korea Ministry of Health and Welfare.

Results

Eight candidate strategies were developed to improve the effectiveness of military anti-smoking interventions as follows: (1) development of outcome enhancement plans for smoking cessation programs for the military, (2) development of differentiated smoking cessation programs for specific groups, (3) building of community network for continuity and accessibility of anti-smoking project, (4) building of industry-academia-government networks for anti-smoking project, (5) improvement of the perception of and strengthen the reward for smoking cessation, (6) development of a training system for army clinicians for the delivery of smoking cessation services, (7) creation of a certification system for smoking cessation programs, and (8) development of an evaluation system of project performance for smoking cessation. Through the analytic hierarchy process survey, the military specificity and its sub-criterion of practicality were selected as the top concerns of decision criteria for the anti-smoking strategies among the decision criteria of outcome improvement, military specificity, publicness, and economic efficiency. The most important strategy was to improve the perception of and strengthen the reward for smoking cessation. This strategy was most focused on the creation of an anti-smoking environment and improvement of the effectiveness of the projects. The creation of a training system for army clinicians for the delivery of smoking cessation services ranked second.

Conclusion

In conclusion, motivating smoking cessation and utilizing well-trained army clinicians were found to be the most important anti-smoking strategies for the Korean military. This study might provide valuable insights for policy makers to reduce tobacco use in the Korean military.
