Determinants of alcohol consumption and marijuana use among young adults in the Republic of Palau.

BACKGROUND: This study aimed to describe the status of alcohol consumption and drug use among young adults as well as their determinants. METHODS: We conducted a cross-sectional study of 356 young adults (aged 18 to 24 years) living in Palau in 2013. The prevalence of self-reported alcohol and marijuana usage were compared within and between sexes, age groups, ethnicities, and education levels. RESULTS: The proportion of current drinking was higher in people aged 21-24 than in those aged 18-20 (73.2% vs. 60.9%, p = 0.09 in men and 48.3% vs. 30.0%, p = 0.02 in women), while that of marijuana use did not differ between the age groups. The proportions of current drinking and marijuana use were higher in Palauan than in other ethnicities (current drinking: 70.6% vs. 40.6%, p = 0.005 in men and 38.8% vs. 16.6%, p = 0.04 in women; lifetime marijuana use: 80.0% vs. 52.9%, p = 0.02 in men and 56.1% vs. 30.6%, p = 0.09 in women). The proportion of frequent (3 times or more) marijuana users was higher for the lower educated than for the higher educated (62.5% vs. 32.1%, p < 0.001 in men and 33.9% vs. 24.4%, p = 0.12 in women). CONCLUSIONS: Sex, age, ethnicity, and education were significant determinants of alcohol and marijuana use.

Profile of Non-communicable Disease Risk Factors Among Young People in Palau.

BACKGROUND: Although non-communicable diseases (NCDs) have become the predominant health problems of Palauan society, there have been no comprehensive data on NCD risk factors available to develop effective control strategies. Therefore, the first Palauan national STEPwise approach to risk factor Surveillance (STEPS) was completed in mid-2013 to provide information on its adult population aged 25 to 64 years. This study aims to obtain corresponding data from the younger adults aged 18 to 24 years, who remained to be surveyed. METHODS: We conducted an epidemiological study, targeting the 18- to 24-year-old age group. A survey station and a mobile team were established to recruit voluntary participants dwelling in Koror. A slightly modified WHO STEPS instrument was used, including a structured questionnaire for behavioral risk factors, physical measurements, and blood tests. RESULTS: A total of 356 young people were recruited during the survey. In both sexes, nearly half of the participants were overweight/obese. The prevalence of hypertension was higher in men than in women (17.6% vs 1.7%). Raised blood glucose and impaired fasting glucose were observed in 3.5% and 5.2% of the total participants, respectively. About 36% of the subjects were observed to have raised levels of total cholesterol. More than 70% of the young people were current tobacco users, in terms of all kinds of tobacco products. CONCLUSIONS: The current survey, for the first time, revealed a high prevalence of NCD risk factors, especially overweight/obesity and tobacco use, among young people in Palau. This indicates that swift measures against NCDs are required even in this young age group.

Suicide-related events among child and adolescent patients during short-term antidepressant therapy.

AIMS: Antidepressants have been of limited use for adolescent subjects with depression because of drug-induced suicide-related events (SRE). Therefore, we investigated actual suicidality and its risk factors during antidepressant therapy among child and adolescent patients in clinical settings. METHODS: The risks of SRE, consisting of suicidal ideation, self-mutilation and suicide attempt, were prospectively monitored among 70 child and adolescent patients (15.4 ± 2.8 years) during the first 3 months of antidepressant therapy. RESULTS: The proportion of SRE decreased from 47.1% to 22.9% after the treatment. Subjects with persistent risks of SRE were significantly characterized by female sex (P < 0.05), psychotic features (P < 0.001), borderline personality disorder (P < 0.01), previous SRE (P < 0.001), and such baseline psychopathology as anhedonia (P < 0.005), irritability (P < 0.005) and hopelessness (P < 0.001). Discriminant analysis showed that baseline severity of SRE, borderline personality disorder and psychotic features were closely associated with SRE during antidepressant therapy. Total scoring using those three pretreatment factors predicted risks of SRE with sufficient sensitivity (81%)/specificity (98%) as well as high positive likelihood ratio (43.9). CONCLUSIONS: These findings suggest that deteriorated risk of SRE in child and adolescent patients receiving antidepressants should not be overestimated while some pretreatment characteristics may be useful to predict the outcome of SRE after antidepressant therapy.
