Perceived discrimination and depressive symptoms: a study of Vietnamese women who migrated to South Korea due to marriage.

International migrants are one group that is vulnerable to discrimination and mental health problems. This study examined the experience of perceived discrimination and its impact on depressive symptoms among women who migrated in the specific context of marriage. Using social constructionism and the stress appraisal model, this study conceptualized perceived discrimination as a potential source of stress and hypothesized that it would negatively impact the mental health of migrant women. A survey sample of 212 Vietnamese marriage migrant women in South Korea was used for the final analysis. Perceived discrimination was measured using the adapted Everyday Discrimination Scale (EDS). Overall, approximately 62% of the sample reported having at least one discriminatory encounter based on the nine items of the EDS. The results of the multivariate analyses indicated that perceived discrimination posed a significant risk to mental health (ß = 0.43, p < .001). The experience of perceived discrimination increased the amount of explained variance of depressive symptoms by 17%. Findings highlighted the adverse mental health consequences of daily unfair treatment and disrespect in interpersonal contexts and the importance of social policies and programs that promote respect for cultural diversity.

Acculturation, Acculturative Stress, and Depressive Symptoms in International Migrants: A Study with Vietnamese Women in South Korea.

Globally, there have been increasing numbers of migrant women; these women are at an increased risk for depressive symptoms. The purpose of this study was to examine the associations among acculturation, acculturative stress and depressive symptoms in Vietnamese women who migrated to South Korea through marriages. We hypothesized that acculturative stress would serve as a mediator in the relationship between acculturation and depressive symptoms. Our findings from surveys with 217 Vietnamese immigrant women showed that the indirect effect of acculturation on depressive symptoms, mediated through acculturative stress [- .15 (.04)], was significant (bias corrected 95% confidence interval for the indirect effect = - .25, - .08). Low levels of acculturation increased acculturative stress, which in turn led to the elevated symptoms of depression. Our findings not only illuminate the adaptation processes of international, female migrants but also suggest avenues to protect and promote their mental well-being.

Preferential accumulation of fatty acids in the testis and ovary of cultured and wild sweet smelt Plecoglossus altivelis.

The effect of dietary lipid on the fatty acid composition of muscle, testis and ovary of cultured sweet smelt, Plecoglossus altivelis, was investigated and compared with that of wild sweet smelt. Cultured fish were fed three different diets for 12 weeks: a control diet rich in docosahexaenoic acid (DHA, 22:6n-3) and eicosapentaenoic acid (EPA, 20:5n-3) (CO group); a diet deficient in DHA and EPA (DP group); and a diet rich in alpha-linolenic acid (ALA, 18:3n-3), but deficient in DHA and EPA (LP group). The fatty acid composition of muscle and gonad lipids was related with dietary fatty acids. Despite the difference in DHA and EPA content in the diets, muscles and gonads, respectively, contained almost equal levels of DHA and EPA in each CO and DP group. However, the muscle and gonad of the LP group showed a lower level of DHA than other groups, due to having the highest level of ALA. In the wild fish muscle, the DHA content was similar to that of CO and DP groups, but the EPA content showed the highest level in all groups. There was no difference in the muscle fatty acid proportions between male and female. On the other hand, the testes of cultured and wild fish were rich in DHA, EPA, docosapentaenoic acid and arachidonic acid, while ovaries were rich in oleic, palmitoleic, linoleic acids and ALA. Moreover, of all the groups, the fish fatty acid composition of the LP group was closest to that of wild fish. These results indicate that in the sweet smelt, tissue n-3 polyunsaturated fatty acids (PUFAs) greater than C20 can be synthesized from dietary precursors and special fatty acids are preferentially accumulated to the testis or ovary, respectively, to play different physiological functions.
