Sexlessness among Married Chinese Adults in Hong Kong: Prevalence and Associated Factors

THE JOURNAL OF SEXUAL MEDICINE, Issue 11 2009
Jean H. Kim ScD
ABSTRACT Introduction., Despite recent media coverage in the topic of sexless marriages in East Asia, population-based studies examining the absence of sexual activity among nonelderly married individuals are scant. Previous studies have not simultaneously examined sociodemographic, physiological, and lifestyle predictors of sexless marriages. Aims., To determine the prevalence of past-year sexlessness and the associated factors among the married Chinese adults in Hong Kong. Methods., An anonymous, population-based telephone survey was conducted on 2,846 married Chinese men and women between the ages of 25 and 59 in Hong Kong. Main Outcome Measures., The prevalence of past-year sexlessness and the associated factors and mental health symptoms were examined. Results., The prevalence of past-year sexlessness between the ages of 25,34 years, 35,44 years and 45,59 years was 5.5, 5.1, and 17.0%, respectively, among married males, and 8.3, 12.4, and 31.6%, respectively, among married females. Older age and poor spousal relationship were associated with sexlessness for females, whereas lack of interest in sex, older age, and lower education were significant factors for males. Married women demonstrated statistically significant associations between sexlessness and poorer mental health indicators, such as lower quality of life and being bothered by the unavailability of a sex partner. Conclusions., Sexlessness is prevalent among certain subgroups of urban Chinese couples in Hong Kong, and the large discrepancy in sexlessness between married men and women in each age strata suggests a high prevalence of extramarital relationships. Contrary to commonly held beliefs, there was a stronger association between sexlessness and poorer psychosocial symptoms among married females than males. Sexless marriages are an underappreciated phenomenon among urban Chinese individuals. Kim JH, Lau JTF, and Cheuk KK.

The Distribution of Follicular Units in the Chinese Scalp: Implications for Reconstruction of Natural-Appearing Hairlines in Orientals

DERMATOLOGIC SURGERY, Issue 6 2002
Ren-Yeu Tsai MD
background. Follicular transplantation using hair in its naturally occurring groups, called follicular units (FUs), has become the most popular technique in hair restoration surgery. Recently follicular transplantation was performed with a qualitative and quantitative concept to achieve the best clinical result. The characteristics and distribution of FUs are well studied in Caucasians and widely applied in hair transplantation surgery. objective. In order to understand the normal distribution of FUs in the Chinese scalp, we counted the number of hairs and FUs in normal Chinese scalp to provide general information for surgical planning and design in bald Chinese patients. methods. A total of 50 normal and 50 bald Chinese adults were enrolled to count the hairs on their scalp. One hundred bald patients receiving hairline reconstruction were also prospectively quantitatively evaluated. results. In normal Chinese scalp, an average 71.78 FUs/cm2 and 137.08 hairs/cm2 were calculated with a follicular density of 1.91 hairs/FU. Two-hair FUs are the predominate group (50.29%). In bald patients, an average of 68.07 FUs/cm2 was found, which was less than that of the occipital scalp in normal nonbald patients. In reconstruction of the frontal hairline, a total of 700,1000 FUs were implanted with an average density of 30 FUs/cm2. conclusion. We found the average number of FUs (0.72 FU/mm2) was less than that in Caucasian patients (1 FU/mm2). The average density of 30 FUs/cm2 implanted was suitable to reconstruct a natural frontal hairline in bald Chinese patients, which can achieve about 40% of normal hair density. Our results could provide the hair surgeon with general information about hair distribution on the Chinese scalp for surgical planning and design in their patients. [source]

Alcohol abuse in a metropolitan city in China: a study of the prevalence and risk factors

ADDICTION, Issue 9 2004

ABSTRACT Aims To investigate the prevalence of alcohol abuse in modern China and to explore the risk factors that may be associated with alcohol abuse. Design A face-to-face interview was carried out in a random sample with 2327 respondents. Setting Respondents were selected randomly from Wuhan City, Hubei Province, China, between May and June 2002. Participants Fifteen,65-year-old urban Chinese adults. Measurements Scores for alcohol abuse and related risk factors were the main measures. Findings (1) Nearly 15% of urban Chinese adults aged 15,65 were alcohol abusers. (2) Deviant drinking habits of mother, schoolmates, colleagues or friends all had a negative impact on the respondent's alcohol drinking behaviours, and higher economic status, current smokers, being male and being older were identified as risk factors related to alcohol abuse. In particular, if a drinker's mother used alcohol frequently then this drinker was more likely to become an alcohol abuser than those drinkers whose mothers did not use alcohol frequently (P = 0.0001). Fathers' drinking behaviours do not have a significant impact on the alcohol abusers. Conclusions In addition to common risk factors such as economic status, deviant peers' and fellows' drinking behaviours and negative attitudes to alcohol drinking, maternal alcohol drinking habit influenced significantly the offspring's drinking habits. Therefore, efficient intervention and education of healthy drinking habits in early motherhood is necessary for Chinese women. [source]

Prevalence and etiology of elevated serum alanine aminotransferase level in an adult population in Taiwan

JOURNAL OF GASTROENTEROLOGY AND HEPATOLOGY, Issue 9 2007

Abstract Background:, The prevalence and etiologies of elevated alanine aminotransferase (ALT) have geographic variations and they are rarely reported in Taiwan. Through a population-based screening study, the prevalence and etiologies of elevated ALT in an adult population of Taiwan were assessed. Methods:, A cross-sectional community study in a rural village of Taiwan was conducted in 3260 Chinese adults (age ,18 years) undergoing ultrasonography (US), blood tests, and interviews with a structured questionnaire. The diagnostic criteria of non-alcoholic fatty liver disease (NAFLD) included alcohol intake <20 g/week for women or <30 g/week for men, negative hepatitis B virus (HBV) and hepatitis C virus (HCV) infections, no known etiologies of liver disease, and US consistent with fatty liver. Results:, The prevalence of elevated ALT was 11.4% (372/3260). The probable cause of this elevation was excess alcohol consumption in 0.8%, HBV in 28.5%, HCV in 13.2%, both HBV and HCV in 2.2%, NAFLD in 33.6%, and unexplained cause in 21.8%. The etiologic distribution of elevated ALT was similar in both genders, although elevation was more common in men compared to women (17.3%vs 6.1%, P < 0.05). The prevalence of elevated ALT in NAFLD was 18.1% (125/691), and the positive predictive value was 33.6% (125/372). The development of NAFLD was related to increasing age (age between 40 years and 64 years, odds ratio [OR] 1.59, 95% confidence interval [CI]: 1.25,2.01; age , 65 years, OR 1.46, 95%CI: 1.08,1.96), fasting plasma glucose (FPG) , 126 mg/dL (OR 1.54, 95%CI: 1.11,2.14), bodymass index (BMI) , 25 kg/m2 (OR 5.01, 95%CI: 4.13,6.26), triglyceridemia , 150 mg/dL (OR 1.96, 95%CI: 1.58,2.42), and hyperuricemia (OR 1.50, 95%CI: 1.22,1.84). Elevated ALT was related to male gender, BMI , 25 kg/m2, and triglyceridemia , 150 mg/dL in subjects without known etiologies of liver disease (all P < 0.05). Conclusions:, Non-alcoholic fatty liver disease appears to be the commonest cause of elevated ALT and presumed liver injury in Taiwan. The development of NAFLD is closely associated with many metabolic disorders. Metabolic disorders are also related to elevated ALT in subjects without known etiologies of liver disease. [source]

Objective The relationship between body mass index (BMI) and stroke incidence and mortality remains controversial, particularly in Asian populations. Methods We conducted a prospective cohort study in a nationally representative sample of 169,871 Chinese men and women age 40 years or older. Data on body weight was obtained at baseline examination in 1991 using a standard protocol. Follow-up evaluation was conducted in 1999 to 2000, with a response rate of 93.4%. Results After excluding those participants with missing body weight or height values, 154,736 adults were included in the analysis. During a mean follow-up of 8.3 years, 7,489 strokes occurred (3,924 fatal). After adjustment for age, gender, physical inactivity, urbanization, geographic variation, cigarette smoking, diabetes, and education, compared with participants of normal weight (BMI 18.5,24.9), relative hazard (95% confidence interval) of incident stroke was 0.86 (0.80,0.93) for participants who were underweight (BMI < 18.5), 1.43 (1.36,1.52) for those who were overweight (BMI 25,29.9), and 1.72 (1.55,1.91) for those who were obese (BMI , 30). The corresponding relative hazards were 0.76 (0.66,0.86), 1.60 (1.48,1.72), and 1.89 (1.66,2.16) for ischemic stroke and 1.00 (0.89,1.13), 1.18 (1.06,1.31), and 1.54 (1.27,1.87) for hemorrhagic stroke. For stroke mortality, the corresponding relative hazards were 0.94 (0.86,1.03), 1.15 (1.05,1.25), and 1.47 (1.26,1.72). Linear trends were significant for all outcomes (p < 0.0001). Interpretation These results suggest that elevated BMI increases the risk of both ischemic and hemorrhagic stroke incidence, and stroke mortality in Chinese adults. ANN NEUROL 2010;67:11,20 [source]
