Suicidality and migration among adolescents in Hong Kong.

Suicide as a cause of death among adolescents and migration as a component of population have been growing in importance. Very little research has been conducted on the connections between migration and suicidality among adolescents in Hong Kong, and so is the aim of this article. It uses census and registration data to study suicide mortality, and sample survey data collected for this purpose to investigate suicide attempt, suicide ideation, and self-injurious behavior. Relations between suicidality and socio-demographic/psychological factors replicated those found in the literature. Duration of residence was found important for the study of suicide among migrants. In both the bivariate and multivariate analyses, although the suicidality levels for short-duration (less than 10 years) adolescent migrants were very much lower than the local-born counterparts, those for the long-duration (10 years or more) migrants were very much higher. The findings support the Healthy Migrant Hypothesis and other related hypotheses in migrant mortality studies. They also reveal, in the light of the Integration Theory of Suicide, the problem of migrant integration into the host culture and society, an important social problem for the government to solve.

Gender differences in suicide risk by socio-demographic factors in Hong Kong.

Some peculiarly low male-to-female suicide ratios have been reported in the Far Eastern populations. This article attempts to investigate whether there are gender differences in suicide risk by socio-demographic factors in Hong Kong, and hereby to explain the low male-to-female suicide ratios. The effects of marital status, duration-of-residence, and occupational status on suicide are first studied by periodic suicide rates in 1990-1992, and 2000-2002, then by Poisson regression. Some interesting results are found: Unlike most findings elsewhere, migration in Hong Kong did not induce suicide; occupational status was negatively related to suicide only for men but not for women; the particularly low male-to-female suicide ratio was not due to a larger protection from marriage for men than for women as reported in the literature, but very probably to a very high suicide rate for the non-working population. The authors suggest some plausible explanations of the findings and hence further research to be conducted.

The long-term effects of auricular therapy using magnetic pearls on elderly with insomnia.

OBJECTIVE: To examine the long-term effect of auricular therapy using magnetic pearls administered for the elderly suffering from insomnia. DESIGN: A follow-up study after a randomized controlled trial. SETTINGS: Four hostels for the elderly in Hong Kong. INTERVENTIONS: This paper focuses on reporting the long-term effect of auricular therapy using magnetic pearls in the experimental group of a randomized controlled study. Fifteen volunteer participants were followed up at 1-, 3-, and 6-month intervals after a 3-week treatment course. OUTCOME MEASURES: Objective sleep parameters using actigraphic monitoring were collected at different intervals of time after the therapy. RESULTS: Results of RANOVA demonstrate that there was a significant difference of nocturnal sleep time (F(2.30,29.90)=3.63, P<0.05) and marginally differences of sleep efficiency (F(4,52)=2.52, P=0.05) at baseline, immediately after the therapy, and at the three time intervals at 1, 3 and 6 months. The results illustrate that the mean nocturnal sleep time (F=4.95, P=0.30, R(2)=0.91) and the mean sleep efficiency (F=13.50, P=0.19, R(2)=0.96) also remained constant over the 6-month follow up period. The results of least square polynomial regression analysis also illustrate that the mean NST (F=4.95, P=0.30, R(2)=0.91) and the mean sleep efficiency (F=13.50, P=0.19, R(2)=0.96) remained constant over the 6-month follow up period. CONCLUSION: The results of this follow up study indicate that auricular therapy using magnetic pearls could have a long-term effect, at least within the observed period of time, on improving the quality as well as the quantity of sleep among the elderly.

A health status indicator for the Chinese elderly in Hong Kong.

This paper proposes an instrument comprising of 28 questions on seven dimensions to assess the quality of life of a subpopulation. Our hierarchical model which utilizes Thurstone's Law of comparative judgment and Mckenna's modification will give a score from 0 to 100 of an individual's overall health quality. Also reported are the results of an implementation of the instrument on an elderly Chinese subpopulation in Hong Kong.

Neonatal onset of medium-chain acyl-coenzyme A dehydrogenase deficiency with confusing biochemical features.

A female neonate was seen because of shock, ketosis, and undetectable blood glucose. Initial urinary findings indicated the possibility of a defect of fatty acid beta-oxidation; subsequent studies showed that she had medium-chain acyl-coenzyme. A dehydrogenase deficiency. This case highlights the fact that the initial symptoms may occur in the first few days of life, and that the presence of ketosis does not exclude the possibility of a fatty acid oxidation defect; the profiles of urinary organic acids and acylglycines may not be characteristic at that time.
