Factors Associated with Pesticide Risk Behaviors among Rice Farmers in Rural Community, Thailand

The need to use large amounts of pesticides has raised environmental health and human health concerns. Several reports reveal that many farmers in Thailand continue to be poisoned through unsafe practices in the use of pesticides. Few studies exist that examine pesticide risk behaviors and beliefs among rice farmers in Thailand. The study objective was to evaluate health beliefs and behaviors associated with pesticide risk behaviors among rice farmers in the Khlong Seven community from March to December 2010. Data collection from 482 rice farmers was completed by observation, in-depth interviews, and focus group discussions. We found the main potential exposure pathways included: take-home exposure; ingestion from food intake, especially vegetables and drinking water; environment risks, especially the proximity of family homes to farms, spray drift areas, and; the most concern stemmed from their practice. Major factors of pesticide poisoning in the Khlong Seven community were the unsafe use of pesticides including erroneous beliefs of farmers about pesticide toxicity, lack of attention to safety precautions, environmental hazards, and information about first aid and antidotes written on the container labels, the use of faulty spraying equipment or lack of proper maintenance of spraying equipment, and wearing protective gear and appropriate clothing during the handling of pesticides. This study concludes that an intervention program is necessary to improve safer pesticide behaviors and to decrease pesticide exposure among rice farmers in Khlong Seven community.

KAP Study on Contraception in Teenage Pregnancy at Antenatal Care Clinic and Delivery Room in Chulalongkorn Memorial Hospital

Objective: To assess knowledge, attitude, and practice about contraception in pregnant teenagers.Materials and Methods: This was a cross-sectional descriptive study. Data collection started from September 2009 to March 2010. Pregnant teenagers, aged 12-19 years old, attending ANC clinic or delivery room at King Chulalongkorn Memorial Hospital were enrolled. The questionnaire consists of four parts; demographic data, contraceptive knowledge, attitudes about pregnancy and contraception, and past contraceptive practices. Data were analyzed using descriptive statistics, chi square test, t-test and Pearson correlation.Results: A total of 150 complete questionnaires from 285 cases of teenage pregnancy in this study period were collected and analyzed. The mean age of subjects was 17.7 years. Only 52.7% used any contraception at first intercourse. Contraceptive pill was the most common method used (59.5%) and only one-fourth chose condom. Up to 74% of participants were pregnant for the first time and 72% informed that their current pregnancies were unintended. The mean contraceptive knowledge score was 70.0 ± 9.7%. Their knowledge short-acting contraception was significantly more than long-acting contraception (P<.001). There was a correlation between knowledge and use of contraception at first intercourse (P=.012) and a trend of correlation between knowledge and attitude although not significant. Most of teenagers decided to use contraception by themselves. When they had any problems, only 19% went to see a doctor. Sources of contraceptive information were mainly from school teaching and mass media.Conclusion: Knowledge on contraception in pregnant teenagers was in average level. There was a correlation between knowledge and the use of contraception at first sexual intercourse. Most cases decided to use contraception themselves (63.5%). Pills was the most common contraceptive method (63.5%)

Effect of immediate neonatal zidovudine on prevention of vertical transmission of human immunodeficiency virus type 1

AbstractObjectives: To describe the effects of various short zidovudine (ZDV) prophylactic regimens on vertical transmission of human immunodeficiency virus type 1 (HIV-1) infection, especially the effect of immediate neonatal ZDV prophylaxis.Materials and Methods: The study included children of HIV-1-infected mothers who were born at a teaching hospital in Bangkok. The ZDV prophylaxis regimens varied by time periods that included: (1) no ZDV (1991–1996); (2) antenatal oral ZDV, 250 mg given twice a day starting at 34 to 36 weeks' gestation and continued until labor (1995–1998); (3) antenatal oral ZDV plus immediate neonatal oral ZDV, 6 mg/0.6 mL/dose started within the first 2 hours after birth and continued at 6-hour intervals for 4 to 6 weeks (1997–1998); and (4) intrapartum intravenous ZDV given in addition to regimen 3 (1998–1999). Neonatal ZDV was administered within 2 hours after birth in 95% of the neonates.Results: In a cohort of 136 children born at least 9 months before the analysis date, the HIV-1 vertical infection rates were: (1) no ZDV, 11 of 48 (22.9%, 95% confidence interval [Cl] = 12.0–37.3); (2) late antenatal ZDV, 10 of 47 (21.3%, 95% Cl = 10.7–35.7); (3) late antenatal ZDV plus immediate neonatal ZDV, 0 of 28 (0%, 95% Cl = 0–12.3); (4) late antenatal, intrapartum intravenous ZDV, plus immediate neonatal ZDV, 0 of 13 (0%, 95% Cl = 0–24.7). An estimated 0% (95% Cl = 0–8.6) of the infants who received immediate neonatal ZDV with or without intrapartum ZDV were infected, as compared with 22.1% (95% Cl = 14.2–31.8 ) of those who received no ZDV or only late antenatal ZDV (P < 0.001).Conclusion: The results of this study suggests high protective effect of immediate administration of neonatal ZDV. Perinatal components of antiretroviral prophylaxis provided the best results for protecting against vertical HIV-1 transmission

Efficacy and tolerability of a monophasic combined oral contraceptive containing nomegestrol acetate and 17β-oestradiol in a 24/4 regimen, in comparison to an oral contraceptive containing ethinylestradiol and drospirenone in a 21/7 regimen

Objectives: The primary objective was to assess the efficacy, cycle control and tolerability of a monophasic combined oral contraceptive (COC) containing nomegestrol acetate (NOMAC) and 17β-oestradiol (E2). Effects on acne were evaluated as a secondary objective. Results: were compared to those of a COC containing drospirenone (DRSP) and ethinylestradiol (EE). Methods Women (aged 1850 years) were randomised to receive NOMAC/E2 (2.5 mg/1.5 mg) in a 24/4-day regimen (n = 1591) or DRSP/EE (3 mg/30 μg) in a 21/7-day regimen (n = 535) for 13 cycles. Results: Estimated Pearl Indices for NOMAC/E2 and DRSP/EE were 0.38 and 0.81 in women aged ≤ 35 years and 0.31 and 0.66 for all women (18-50 years), respectively. Scheduled withdrawal bleedings were shorter and lighter among users of NOMAC/E2 and were sometimes absent altogether. Intracyclic bleeding/spotting was infrequent in both groups, and decreased over time. Type and frequency of adverse events were similar to those typically reported for COCs. Conclusions: These data show that NOMAC/E2 provides high contraceptive efficacy with acceptable cycle control as well as an overall adverse event profile similar to that of DRSP/EE

A Comparative Efficacy of Low-Dose Combined Oral Contraceptives Containing Desogestrel and Drospirenone in Premenstrual Symptoms

Objective. To compare the efficacy of low-dose COC containing desogestrel (DSG) with drospirenone (DRSP) in the changes of premenstrual symptoms. Methods. In an open-label randomized controlled trial, 90 women with premenstrual syndrome who required COC were randomly recruited and allocated equally to receive either 6 cycles of 20 micrograms ethinyl estradiol (EE)/150 micrograms DSG (DSG group) or 20 micrograms EE/3 mg DRSP (DRSP group) in 24/4 extended regimen. Analysis of covariance and repeated analysis of variance were used to determine the difference of mean Women's Health Assessment Questionnaire (WHAQ) scores changes between groups, within group, and in premenstrual, menstrual, and postmenstrual phases. Results. Baseline characteristics and WHAQ scores were comparable. At the ends of the 3rd and the 6th cycles, mean WHAQ scores of all the 3 phases in DRSP group showed significant reduction and were significantly lower than those in DSG group. DSG group showed significant reduction in both premenstrual and menstrual phases after the 6th cycle. Adverse effects were comparable in both groups. In conclusion, low-dose COC containing either DSG or DRSP reduced premenstrual symptoms, but the latter showed greater efficacy and earlier reduction

The Effect of a Single Bout of Chinese Archery on Core Executive Functions in Preadolescent Children in Shanghai

Background: Recent literature has demonstrated that acute physical activity benefits the transfer of executive functions. However, further studies indicated the type of variability in the effect of physical activity on executive functions. Therefore, this study initially explored the effect of a single bout of Chinese archery on subdomains of core EFs in preadolescent children; Method: Eligible participants were allocated either an intervention group (n = 36) or a control group (n = 36). The subjects in the intervention group received a 45-min Chinese archery session. The primary outcomes were the performance of core EFs (inhibition control, working memory, and cognitive flexibility) in preadolescent children, assessed with psychological paradigms (Fish Flanker Task, N-Back Task, and DCCS (Border version), respectively). Paired t-test and ANCOVA were used to analyze the mean difference in the performance of core EFs within and between subjects, respectively; Results: Considering reaction time and accuracy, we explored the impressive performance in three cognitive tasks with acute Chinese archery; Conclusion: The finding suggests that a single bout of Chinese archery benefited three subdomains of core EFs in healthy preadolescent children

Prevalence of Diabetes and Relationship with Socioeconomic Status in the Thai Population: National Health Examination Survey, 2004–2014

Objective. To determine the prevalence and trend of diabetes, related glycemic control, and influential socioeconomic (SES) factors in the Thai population aged ≥20 years during 2004–2014. Methods. Data from the Thai National Health Examination Survey 2004, 2009, and 2014 were used. Age-adjusted prevalence was calculated, and the associations of education levels with prevalence of diabetes and glycemic control were examined using logistic regression. Results. Age-adjusted prevalence of diabetes increased from 7.7% in 2004 to 7.8% in 2009 and 9.9% in 2014 (8.9% among men and 10.8% among women). Proportions of undiagnosed diabetes were slightly decreased but remained high in 2014 (51.2% for men and 41.3% for women). Diabetes prevalence was higher among those with primary education in both sexes; however, undiagnosed diabetes was higher among women with secondary and university educations. The percentages of those treated and controlled slightly improved among men (45.9%) but not among women (36.4%). Unmet glycemic control was also higher among women with secondary education levels and among men with university-level educations. Conclusions. Epidemic diabetes continues to grow in the Thai population, particularly in individuals with lower educational attainment. Measures to detect new cases and strengthen glycemic control should be scaled up
