Regular dental check-up status and related factors among Thai residents in Japan.

The objectives of this online study were to determine the status of regular dental check-ups among Thai nationals living in Japan and to identify barriers to regular dental check-ups by comparing them with general health check-ups. We conducted the online survey twice, in 2021 and 2022, among Thai nationals aged 18 years and older living in Japan via social networking services by an organization that supports Thai nationals living in Japan. Respondents between the ages of 30 and 59 were included in this study. Independent factors included gender, age, length of stay in Japan, family economic status, confidence in Japanese and stay for work purposes. Dependent factors were regular dental check-ups and general health check-ups in the past year. Chi-square tests and multiple logistic regression analyses were used for analysis. 56.6% of respondents had regular dental check-ups. The adjusted odds ratio for the proportion of people with regular dental check-ups was significantly higher for those with high economic status, 2.15 (1.06-4.33), compared with those with low economic status. It was also significantly higher 1.88 (1.10-3.21) for those with confidence in the Japanese language compared with those without. The study suggested the need for Japanese language support in addition to financial support for dental health prevention programs for foreigners living in Japan.

The effect of video-mediated communication on father-infant bonding and transition to fatherhood during and after Satogaeri Bunben.

AIMS: The study aimed to explore the effect of video-mediated communication on father-infant bonding and transition to fatherhood during and after Satogaeri Bunben. BACKGROUND: Satogaeri Bunben is a Japanese perinatal tradition that results in the pregnant wife and husband living apart, which may interfere with father-infant bonding and transition to fatherhood. DESIGN/METHODS: A mixed-methods study was conducted from July 2012 to November 2015. Participants were divided into two groups (Treatment/Control). Quantitative data included Taiji kanjyo Hyotei Syakudo (TKHS) , communication methods, husband's visitation records and video-mediated communication records and satisfaction of video-mediated communication experience. Qualitative data included participants' journal entries about their experience and feelings toward their infants during Satogaeri Bunben. RESULTS: Fourteen treatment and thirteen control dyads/couples participated in the study. There were significant differences between groups in the frequency of fathers' visitation during Satogaeri Bunben, as well as on the THKS between groups in cross-sectional analysis and in treatment group in longitudinal analysis. Fathers' journal entries revealed the use of video-mediated communication in both groups, specifically commenting about these experiences and the impact of additional visual cues when communicating. CONCLUSION: Video-mediated communication provides a sense of virtual co-presence, which may help support father-infant bonding and transition to fatherhood; however, it does not completely substitute for face-to-face interaction.

The Impact of a Video-Mediated Communication on Separated Perinatal Couples in Japan.

Japanese communication relies heavily on nonverbal cues and context. The purpose of this study was to examine the impact of video-mediated communication (VMC) on communication satisfaction and marital relationships in young couples separated during the perinatal period as they honor the Japanese tradition of Satogaeri Bunben. Couples were assigned to the VMC treatment group ( n = 14) or control group ( n = 13). A mixed-methods approach to data collection and analysis was used. Longitudinal quantitative analysis from the Primary Communication Inventory and Intimate Bond Measure revealed significant differences between the Husband groups. Primary Communication Inventory and Intimate Bond Measure were strongly correlated regardless of group. Qualitative analysis of participant diaries revealed the addition of visual cues helped create a sense of "virtual co-presence," which was both positive and negative. In conclusion, VMC appears to improve communication in the separated Japanese perinatal couples, especially through the addition of visual cues provided with VMC.

[Mortality rates of foreign national residents in Japan: comparison with the Japanese population and a possible healthy migrant effect].

Objectives　This study clarified the health status of foreign nationals residing in Japan by comparing their current mortality rates with those of the Japanese population.Methods　We focused on foreign national residents and used official statistical data from 2010. Due to the possible overestimation of published death rates (PDRs), we computed calculated death rates (CDRs) for foreign national residents, using the number of registered foreign national residents as the denominator. We obtained this number from the Statistics on Foreign National Residents provided by the Ministry of Justice.Results　The all-cause age-adjusted mortality rates (per 100,000 population) of foreign national residents were 571.5 for men and 316.1 for women. The ratios with reference to the mortality rates of the Japanese population were 1.1 and 1.0 for men and women, respectively, indicating that the age-adjusted mortality rates for foreign national residents were similar to those of the Japanese population. However, the rate ratios by age group were 0.3-0.5 for those aged 20-34 years, 0.6-1.0 for those aged 35-59 years, and 1.0-1.4 for those aged ≥60 years, suggesting that the mortality rate of foreign national residents increases with age when compared to that of the Japanese population. Although the foreign population are thought to be disadvantaged in many ways, the mortality rates of the young and middle-aged groups were lower than those of the Japanese population. A similar tendency was observed in the cause-specific mortality rates of the young and middle-aged groups of foreign national residents, except the rates of mortality due to accidents and suicide in the middle-aged group, which were higher than those of the Japanese population. In those aged ≥60 years, the mortality rates were higher than those of the Japanese population overall, especially the mortality rates due to suicide.Conclusion　These results suggest that young and middle-aged foreign national residents are relatively healthy and that a healthy migrant effect exists in Japan. Because this health advantage may either decrease or converge with that of the native population after long-term residence as a previous research reported; without intervention, these lower mortality rates in the young and middle-aged foreign national residents may eventually increase or even exceed those of the Japanese population. More attention should be paid to middle-aged foreign national residents who have higher rates of mortality due to accidents and suicide as well as foreign national residents aged ≥60 years, who have an extremely high mortality rates due to suicide. Although overestimations and underestimations are still possible, CDRs are considered more appropriate than PDRs, since the impact is smaller. Future investigations should focus on the healthy migrant effect in Japan in order to address current and upcoming health issues among foreign national residents.

Methamphetamine use and correlates in two villages of the highland ethnic Karen minority in northern Thailand: a cross sectional study.

BACKGROUND: The prevalence of methamphetamine use and human immunodeficiency virus (HIV) incidence are high in lowland Thai society. Despite increasing social and cultural mixing among residents of highland and lowland Thai societies, however, little is known about methamphetamine use among ethnic minority villagers in the highlands. METHODS: A cross-sectional survey examined Karen villagers from a developed and a less-developed village on February 24 and March 26, 2003 to evaluate the prevalence and social correlates of methamphetamine use in northern Thailand. Data were collected in face-to-face interviews using a structured questionnaire. RESULTS: The response rate was 79.3% (n = 548). In all, 9.9% (males 17.6%, females 1.7%) of villagers reported methamphetamine use in the previous year. Methamphetamine was used mostly by males and was significantly related to primary or lower education; to ever having worked in town; to having used opium, marijuana, or heroin in the past year; and to ever having been diagnosed with a sexually transmitted infection (STI). CONCLUSION: Since labor migration to towns is increasingly common among ethnic minorities, the prevention of methamphetamine use and of HIV/STI infection among methamphetamine users should be prioritized to prevent HIV in this minority population in Thailand.

[Epidemiology of sexually transmitted diseases in Japan--its international characteristics].

Japan has witnessed the rise of STDs, and the increase in the number of HIV cases infected through sexual contact in the last decade. Background of these trends will be the exceptionally high prevalence of paid sex in Japan among developed countries and the diversified unprotected sexual behaviors that have prevailed among general population since 1990s. STDs are also increasing and HIV infection through sexual contact has resumed to increase among other developed countries in the same period of time. Coordinated research among developed countries is becoming increasingly important to clarify the specific and general causes of such phenomena and thus to explore the possibility of coordinated responses toward these global challenges.

Prevalence and correlates of sexual behaviors among karen villagers in northern Thailand.

A cross-sectional survey was conducted in two mountainous villages of the Karen, a major ethnic minority in Thailand. The participants were 566 villagers aged 15-54 years (371 in Village A, 195 in Village B; response rate=81.9%). Premarital/extramarital sex was experienced by 10-20% of the sexually active respondents and sex with a female sex worker (FSW) by 12.6% of males. Premarital sex was independently associated with being a Christian and occupational experience in town; extramarital sex was associated with Village A and drug use; sex with a FSW was associated with being unmarried, a nonfarmer, and occupational experience in town. Approximately 80% of the married participants never used a condom with their spouse, and nearly one-third never did so with a boy/girlfriend or a FSW. A history of sexually transmitted infections (STIs) was associated with sex with a FSW. These findings suggest that nontraditional sexual practices are prevalent and could potentially threaten Karen communities with the spread of HIV.

Psychological process from hospitalization to death among uninformed terminal liver cancer patients in Japan.

BACKGROUND: Although the attitude among doctors toward disclosing a cancer diagnosis is becoming more positive, informing patients of their disease has not yet become a common practice in Japan. We examined the psychological process, from hospitalization until death, among uninformed terminal cancer patients in Japan, and developed a psychological model. METHODS: Terminal cancer patients hospitalized during the recruiting period voluntarily participated in in-depth interviews. The data were analyzed by grounded theory. RESULTS: Of the 87 uninformed participants at the time of hospitalization, 67% (N = 59) died without being informed of their diagnosis. All were male, 51-66 years of age, and all experienced five psychological stages: anxiety and puzzlement, suspicion and denial, certainty, preparation, and acceptance. At the end of each stage, obvious and severe feelings were observed, which were called "gates." During the final acceptance stage, patients spent a peaceful time with family, even talking about their dreams with family members. CONCLUSION: Unlike in other studies, the uninformed patients in this study accepted death peacefully, with no exceptional cases. Despite several limitations, this study showed that almost 70% of the uninformed terminal cancer patients at hospitalization died without being informed, suggesting an urgent need for culturally specific and effective terminal care services for cancer patients in Japan.

Proteomic analysis of rice embryo: an approach for investigating Galpha protein-regulated proteins.

The rice dwarf1 (d1) mutant, which lacks the alpha subunit of a heterotrimeric G protein (Galpha protein), shows abnormal morphology due to shortened internodes, dark green leaves and grains that are small and round. Proteome analysis was used in this study to aid in determining the function of Galpha protein in rice embryos. Using 2-DE, seven seed embryo proteins were shown to be down-regulated in the d1 mutant as compared with its wild type. These seven proteins included a receptor for activated C-kinase (RACK) and six rice embryo globulin-2 proteins (REG2). The six REG2 have similar molecular masses with minor differences in pI. In addition to the reduced accumulation of RACK in the d1 mutant, the increase in QL/d1, in which a constitutively active form of the Galpha protein is expressed, was significantly higher as compared with wild type. The level of accumulation of these seven proteins during seed development and maturation did not change significantly until the 2nd wk after pollination. Reduced accumulation of these seven proteins started in the d1 mutant at the 3rd wk after pollination, and continued until seed maturation was complete. All seven proteins were completely absent 24 h after imbibition in both d1 mutant and its wild type. However, the phytohormone abscisic acid promoted the expression level of RACK after imbibition in the wild type as compared with d1 mutant. These results suggest that RACK is regulated by Galpha-protein and plays an important role in a basic cellular process as well as in rice embryogenesis and germination.
