The influences of socio-individual determinants and health information seeking on health-promoting behaviors among migrant women: A cross-sectional study.

AIM: This study aimed to examine the effects of socio-individual and health information-seeking variables on health-promoting behaviors among migrant women living in Korea. METHODS: A descriptive, cross-sectional design was used. A convenience sample comprising 190 Filipino marriage-migrant women from G City and J province, South Korea, were recruited between November and December 2015. Participants completed self-report surveys examining health-promoting behaviors, health information seeking, and socio-individual determinants. RESULTS: The most popular health information sources were healthcare professionals (39.0%), family or friends (31.6%), and the Internet (28.9%). Most respondents (90.5%) possessed smart devices; 55.8% used them to seek health information, while 9.5% used health-related applications. The health information that migrant women searched for online mainly concerned their health, diet/nutrition, and physical activity. Education (ß = .15, p = .008), health status (ß = -.10, p = .038), and smart device possession (ß = .20, p = .032) were factors influencing health-promoting behaviors. CONCLUSIONS: Considering the high use of smart devices among migrant women in Korea, these findings suggest the need for an accessible, reliable, and easily understandable Internet-based health information source to facilitate their health-promoting behaviors.

Reinterpretation of curved Hammett plots in reaction of nucleophiles with aryl benzoates: change in rate-determining step or mechanism versus ground-state stabilization.

A kinetic study is reported for the reaction of the anionic nucleophiles OH-, CN-, and N 3 - with aryl benzoates containing substituents on the benzoyl as well as the aryloxy moiety, in 80 mol % H2O - 20 mol % dimethyl sulfoxide at 25.0 degrees C. Hammett log k vs sigma plots for these systems are consistently nonlinear. However, a possible traditional explanation in terms of a mechanism involving a tetrahedral intermediate with curvature resulting from a change in rate-determining step is considered but rejected. The proposed explanation involves ground-state stabilization through resonance interaction between the benzoyl substituent and the electrophilic carbonyl center in the two-stage mechanism. Accordingly, the data are nicely accommodated on the basis of the Yukawa-Tsuno equation, which gives linear plots for all three nuceophiles. Literature reports of the mechanism of acyl transfer processes are reconsidered in this light.
