Perception of premenstrual syndrome and attitude of evaluations of work performance among incoming university female students.

BACKGROUND: Premenstrual syndrome (PMS) is a common condition, and for 5% of women, the influence is so severe as to interfere with their mental health, interpersonal relationships, or studies. Severe PMS may result in decreased occupational productivity. The aim of this study was to investigate the influence of perception of PMS on evaluation of work performance. METHODS: A total of 1971 incoming female university students were recruited in September 2009. A simulated clinical scenario was used, with a test battery including measurement of psychological symptoms and the Chinese Premenstrual Symptom Questionnaire. RESULTS: When evaluating employee performance in the simulated scenario, 1565 (79.4%) students neglected the impact of PMS, while 136 (6.9%) students considered it. Multivariate logistic regression showed that perception of daily function impairment due to PMS and frequency of measuring body weight were significantly associated with consideration of the influence of PMS on evaluation of work performance. CONCLUSION: It is important to increase the awareness of functional impairments related to severe PMS.

Low socioeconomic status may increase the risk of central obesity in incoming university students in Taiwan.

BACKGROUND: Obesity is related to social disparity. The objective of the study was to evaluate different indicators of parental SES with the association of central obesity in young adult Taiwanese students. METHODS: This study was cross-sectionally designed and a total of 4552 subjects were recruited. Each subject completed a self-administrated questionnaire and received anthropometric and laboratory measurements. The indicators of SES in study subjects included parental education, occupation, household incomes, childhood and current index of social position (ISP), measured according to the modified Hollingshead's ISP. Central obesity was defined as waist circumference ≥90 cm in men and ≥80 cm in women. RESULTS: The prevalence of central obesity was 10.7% in this study. When compared to subjects with normal waist circumferences, subjects with central obesity were older, had a higher BMI, both systolic and diastolic blood pressure, a higher proportion of male gender, family history of diabetes and hypertension, alcohol consumption habit, and a higher proportion of low current household income, current parental blue collar occupational level, and lower current and childhood parental ISP level. Multivariate analysis showed the current parental household income and ISP were significantly higher indicators of risk of central obesity after adjustment for possible confounding factors. The odds ratios were 1.26 and 1.30, respectively. CONCLUSIONS: Our results showed that low household income and current ISP were independently associated with the risk of central obesity. Therefore, young adults with low SES should be an important target group for prevention and management of central obesity in school health promotion programs.

Factors associated with premenstrual syndrome - a survey of new female university students.

Premenstrual syndrome (PMS) can impact an individual's interpersonal relationships, social interactions, productivity, lifestyle, school performance and emotional well-being. This study was designed to explore the factors associated with PMS in new female university students in Taiwan. The test battery included a self-administered structured questionnaire, the five-item brief symptoms rating scale, the Pittsburgh Sleep Quality Index and the Chinese Premenstrual Symptom Questionnaire. Additionally, details of the participants' lifestyles and family and personal histories of physical illness were recorded. Serum lipids were also measured. Of all the participants (N = 1699), 39.85% were defined as having PMS. Using logistical regression analysis, we found a positive relationship between PMS and consuming more foods containing egg yolk, greater alcohol intake, poorer sleep quality, higher likelihood of psychiatric morbidity, family history of dyslipidemia, and a higher serum cholesterol level. The results show that PMS is prevalent among new female university students and that lifestyle and nutritional/metabolic factors may play a role in this disorder.

A study on the sleep quality of incoming university students.

This study was designed to examine the prevalence and the risk factors of poor sleep quality in 4318 incoming university students in Taiwan. The test battery comprised a self-administered structured questionnaire, including items related to personal medical history and lifestyle habits, the Measurement of Support Functions (MSF), Pittsburgh Sleep Quality Index (PSQI), Chinese Internet Addiction Scale-Revision (CIAS-R), neuroticism subscale of the Maudsley Personality Inventory (MPI), and the 12-item Chinese Health Questionnaire (CHQ-12). Of the total study population, 2360 students (54.7%) were classified into the poor sleep quality group, as defined by a PSQI score ≥6. Based on the results of multivariate logistic regression analysis, poor sleep quality was significantly associated with undergraduate students, female gender, skipping breakfast, tea drinking, a higher tendency toward internet addition, poor social support, higher neuroticism, and higher CHQ scores. Poor sleep quality is prevalent among incoming university students in Taiwan, and more work is needed on the identification of the factors influencing poor sleep, and in providing systematic education in the importance of sleep and time management skills to university students.

Increased arterial stiffness in subjects with impaired glucose tolerance and newly diagnosed diabetes but not isolated impaired fasting glucose.

CONTEXT: Studies have shown that diabetes mellitus increased brachial-ankle pulse-wave velocity (baPWV), but the impact of impaired fasting glucose (IFG) and impaired glucose tolerance (IGT) remains controversial. OBJECTIVE: Our objective was to investigate the impact of the different glycemic states on baPWV in a relatively healthy Chinese population. DESIGN, SETTING, AND PATIENTS: We enrolled 4938 subjects in the health examination center of the National Cheng Kung University Hospital from October 2006 to August 2009 after excluding those who were under medications for diabetes, hypertension, or hyperlipidemia or had a history of cardiovascular disease. MAIN OUTCOME MEASURES: The baPWV values to assess arterial stiffness were calculated as the distance traveled by the pulse wave divided by the time taken to travel the distance. The participants were classified into normal glucose tolerance (NGT; n = 3777), isolated IFG (n = 221), IGT (n = 726), and newly diagnosed diabetes (NDD; n = 214) groups. RESULTS: The mean values of baPWV were 1284.9 ± 205.2, 1379.6 ± 226.8, 1408.1 ± 251.7, and 1500.8 ± 282.5 cm/sec in NGT, isolated IFG, IGT, and NDD groups, respectively. The isolated IFG, IGT, and NDD groups had a higher baPWV value as compared with the NGT group. In a multiple linear regression test, both IGT and NDD groups, but not the isolated IFG group, had significantly higher baPWV values after adjustment for age, sex, body mass index, waist to hip ratio, smoking, alcohol consumption, habitual exercise, systolic blood pressure, and lipid profiles. CONCLUSIONS: Subjects with IGT and NDD, but not isolated IFG, exhibit a greater arterial stiffness.

Sleep duration is a potential risk factor for newly diagnosed type 2 diabetes mellitus.

U-shaped patterns have been observed for the relationship between sleep duration and diabetes. In addition, prediabetes is associated with the risk of cardiovascular diseases and diabetes. However, there are few studies investigating the relationship between sleep duration and prediabetes/newly diagnosed diabetes. The aim of this study is to examine the relationship between sleep duration and prediabetes/newly diagnosed diabetes in a Taiwanese population. After excluding the subjects with a high risk of obstructive sleep apnea, those with a positive history of diabetes, or those taking hypnotic drugs, a total of 3470 adults were recruited from a health checkup center. Each subject completed a self-administrated structured questionnaire on sleep duration and lifestyle factors. Prediabetes/diabetes was defined following the definition of the American Diabetes Association. Subjects with different sleep durations were classified into short (<6.0 hours), normal (6.0∼8.49 hours), and long sleepers (≥8.5 hours). The proportion of subjects with normal glucose tolerance, prediabetes, and newly diagnosed diabetes was 71.9%, 22.9%, and 5.2%, respectively. There were significant differences in age, sex, weight, education level, body mass index, waist-to-hip ratio, systolic and diastolic blood pressure, alcohol and coffee drinking habits, family history of diabetes, and sleep duration among the 3 glycemic groups. In multinomial regression, both short and long sleepers had a higher risk of newly diagnosed diabetes; and the odds ratio were 1.55 (95% confidence interval, 1.07-2.24) and 2.83 (1.19-6.73), respectively. However, sleep duration was not found to relate to prediabetes. In conclusion, both short and long sleep durations were independently associated with newly diagnosed diabetes, but not with prediabetes.

The risk factors of Internet addiction--a survey of university freshmen.

This study was designed to explore the risk factors of Internet addiction in 1360 freshmen of the National Cheng Kung University in Taiwan in 2003. The test battery included a self-administrated structured questionnaire, the Chinese Internet Addiction Scale-Revision (CIAS-R), the 12-item Chinese Health Questionnaire (CHQ-12), the Measurement of Support Functions (MSF), and the neuroticism subscale of the Maudsley Personality Inventory (MPI). Of the total study population, there were 680 college freshmen (17.9%) in the Internet addiction group, as defined by high CIAS-R scores. Using logistic regression analyses, we found positive relationships between Internet addiction and male gender, neuroticism scores and the CHQ score. In addition, the freshmen who skipped breakfast and those who had poorer social support also had a higher probability of Internet addiction. Internet addiction is prevalent among university freshmen in Taiwan. Risk factors included male gender, habit of skipping breakfast, mental health morbidity, deficient social support; and neurotic personality characteristics.
