Populous, economically dynamic, and rapidly urbanizing, the Asia Pacific both reflects and strongly shapes trends in global public health. A comparative assessment of chronic disease prevalence, risk factors, and policy responses in nine Pacific Rim cities shows that chronic diseases are rapidly becoming the leading cause of morbidity and mortality even in the lower income cities of the Pacific Rim. Policy responses are heterogeneous, with few sufficiently funded or adequately informed by evidence. Much could be learned from comparative research and rigorous evaluation of prevention and control initiatives in this region.

The objective of this paper is to estimate the causal effect of coresidence with an adult child on depressive symptoms among older widowed women in South Korea. Data from the first and second waves of the Korea Longitudinal Study of Aging were used. Analysis was restricted to widowed women aged ≥ 65 years with at least one living child (N=2,449). We use an instrumental variable approach that exploits the cultural setting where number of sons predicts the probability of an elderly woman's coresidence with an adult child but is not directly correlated with the mother's depressive symptoms. Our models adjust for age, education, total assets, residence, functional limitations, self-rated health, and various illnesses. Our robust estimation results indicate that, among older widowed women, coresidence with an adult child has a significant protective effect on depressive symptoms, but that this effect does not necessarily benefit those with clinically relevant depressive symptoms. Future demographic and social transitions in South Korea portend that older women’s increasing vulnerability to poor mental health is an important though less visible public health challenge.

The prevalence of antimicrobial resistance (AR) limits the therapeutic options for treatment of infections, and increases the social benefit from disease prevention. Like an environmental resource, antimicrobials require stewardship. The effectiveness of an antimicrobial agent is a global public good. We argue for greater use of economic analysis as an input to policy discussion about AR, including for understanding the incentives underlying health behaviors that spawn AR, and to supplement other methods of tracing the evolution of AR internationally. We also discuss integrating antimicrobial stewardship into global health governance.The prevalence of antimicrobial resistance (AR) limits the therapeutic options for treatment of infections, and increases the social benefit from disease prevention.
