EFFECT OF INSTITUTION-BASED MANAGEMENT FOR ELDERLY HEALTH PROMOTION PROGRAM IN NORTHEASTERN THAILAND.

The increasingly aging population raises a major challenge for health care in Thailand and worldwide. Health promotion has been considered a strategy for improving elderly quality of life. There are a small number of elderly people living in government elderly services in Thailand, and little is known about their health promotion behaviors and how these behaviors have been shaped in an institution-based setting. This study aimed to examine the current situation and effectiveness of the Institution-based Management for Elderly Health Promotion (IBM-EHP) program in enhancing the health and health promotion behaviors of the elderly living in two out of five government elderly home service institutes (GEHSI) in northeastern Thailand. The elderly participants in one GEHSI were assigned into the management group and received the IBM-EHP program (n=60), and those in another GEHSI were in the control group and received the usual care provided by the institution (n=55). Before and after (six months) the program implementation, assessments of knowledge, self-efficacy, received social support, health promotion behaviors, and health status depicted by fasting plasma glucose level and lipid profile of the participants in both groups were performed. Data collection used an interview guide, and clinical and diagnostic measurement methods. Data analysis used frequency, mean, standard deviation, paired simple t-test, independent t-test, and multiple regression. Results indicated that the management group, compared to the control group, demonstrated improvements in perceived self-efficacy, received social support, health promotion behaviors, and HDL-C level (p<0.05). Perceived self-efficacy and received social support were predictive factors, which contributed to explain 50.6% of the health promotion behaviors of the institutionalized elderly participants in the management group. Modification solutions for suitable health promotion behaviors of the institutionalized elderly persons should emphasize on enhancing their self-efficacy and social support from the elderly home service institute and their peers.

Adherence to antiretroviral therapy (ART) among people living with HIV (PLHIV): a cross-sectional survey to measure in Lao PDR.

RATIONALE: Since 2001, antiretroviral therapy (ART) for people living with HIV (PLHIV) has been available in the Lao People's Democratic Republic (PDR). A key factor in the effectiveness of ART is good adherence to the prescribed regimen for both individual well-being and public health. Poor adherence can contribute to the emergence of drug resistant strains of the virus and transmission during risky behaviors. Increased access to ART in low-income country settings has contributed to an interest in treatment adherence in resource-poor contexts. This study aims to investigate the proportion of adherence to ART and identify possible factors related to non-adherence to ART among people living with HIV (PLHIV) in Lao PDR. METHODS: A cross-sectional study was conducted with adults living with HIV receiving free ART at Setthathirath hospital in the capital Vientiane and Savannakhet provincial hospitals from June to November 2011. Three hundred and forty six PLHIV were interviewed using an anonymous questionnaire. The estimation of the adherence rate was based on the information provided by the PLHIV about the intake of medicine during the previous three days. The statistical software Epidata 3.1 and Stata 10.1 were used for data analysis. Frequencies and distribution of each variable were calculated by conventional statistical methods. The chi square test, Mann-Whitney test and logistic regression were used for bivariate analyses. Multiple logistic regression analysis was conducted to determine the predictors of non-adherence to ART. A p-value < 0.05 was considered to indicate statistical significance. RESULTS: Of a total of 346 patients, 60% reported more than 95% adherence to ART. Reasons for not taking medicine as required were being busy (97.0%), and being forgetful (62.2%). In the multivariate analysis, educational level at secondary school (OR=3.7, 95% CI:1.3-10.1, p=0.012); illicit drug use (OR=16.1, 95% CI:1.9-128.3, p=0.011); dislike exercise (OR=0.6, 95% CI:0.4-0.9, p=0.028), and forgetting to take ARV medicine during the last month (OR=2.3, 95% CI:1.4-3.7, p=0.001) were independently associated with non-adherence. CONCLUSIONS: Non-adherence to ART was associated with individual factors and exposure to ART. Priority measures to increase adherence to ART should aim to intensify counseling and comprehensive interventions, such as guidance for PLHIV on medication self-management skills, tailoring the regimen to the PLHIV life style, and improving adherence monitoring and health care services.

A randomized controlled trial to improve the quality of life of type 2 diabetic patients using a self-help group program.

The purpose of study was to determine the effect of a self-help group program on the quality of life among type 2 diabetic patients. The study subjects were type 2 diabetic patients attending one of six studied health centers or a community hospital in Saraburi Province, Thailand. At each health center/hospital, the patients were randomly allocated into the intervention group attending the self-help group program or the control group receiving diabetic services. Information was collected from September 2007 to April 2008 using a structured questionnaire with interview technique at baseline, 12 and 24 weeks. One hundred forty-six patients completed the program. Five self-help group programs carried out for 16 weeks gave instruction regarding building-up good relationships, improvement of knowledge about diabetes and skills for dietary control, skills in physical exercise, improvement of group structure, improvement of training skills for group leaders, self-monitoring, motivation in self-care activities and sharing experiences among group members. Descriptive statistics were used to provide basic information regarding the two groups. For analytical purposes the chi-square test and t-test were applied. The majority (77.4 %) of study participants were females. Most patients were either > or = 50 years old (52%) or 40-49 years old (37%). The intervention resulted in significantly higher scores in quality of life compared to controls at 12 and 24 weeks (p < 0.05). The findings indicate the program is effective for improving perceived quality of life. The program focused on enhancement of experience sharing among group members and participation in problem-solving. We recommend implementing this program for diabetic patients and patients with other chronic diseases at primary health care level.

Migrants and malaria risk factors: a study of the Thai-Myanmar border.

The objective of this study was to investigate factors influencing self-reported malaria among migrants living along the Thai-Myanmar border. Songkaria Village, with 1600 inhabitants and 290 households in Sangkhla Buri District, Kanchanaburi Province, was selected for the study due to its intense malaria transmission. One hundred twenty-five households were randomly selected. Household members were interviewed about the history of malaria, socioeconomic status and knowledge and practices in regard to malaria using a structured questionnaire. Of the respondents, 10%, 42%, and 48% belonged to the Thai, Mon, and Karen ethnic groups, respectively. About 40 % of Thai and Karen migrants and almost 30% of Mon migrants reported having suffered from malaria at least once. Multivariate analysis focused on migrants. The results identified three independent factors for previous malaria: a high risk occupation, ie working primarily in the forest [odds ratio (OR), 3.55; 95% confidence interval 1.3-10.0], ability to read Thai [OR, 4.13 (1.5-11.7)], and correct knowledge about malaria symptoms [OR, 5.18 (1.1-23.5)]. Working conditions among migrants played a major role in acquiring malaria. They could not afford to apply additional preventive measures, such as using a mosquito net or repellent to be used while working. The concept of enhancing the environment for migrants to enable them to protect themselves against malaria needs to be examined. Ways and means of improving the economic conditions of migrants should be considered to minimize exposure to the vector.

Improved control of non-communicable diseases (NCDs) requires an additional advanced concept for public health - a perspective from a middle-income country.

A major consequence of all elements of the 'epidemiological transition' is the rapid emergence of non-communicable diseases (NCDs) in low- and middle-income countries. In contrast to the outcomes of the 'Alma Ata Conference for Primary Health Care', it has not yet been possible to introduce an equally powerful health policy for the prevention and control of NCDs. Major strategies so far are to advise individuals not to smoke and drink alcohol in excess. Additionally, 'healthy' nutrition and increased physical activity are also advocated. Policy for preventing and working against NCDs is now part of the Sustainable Development Goals, specifically target 3.4. So far, attempts to soften the influence of NCDs on the health of the people in low- and middle-income countries have been unsuccessful. It is argued here that additional concepts on how public health could operate against NCDs are needed.  Major risk factors for NCDs interfere with and alter complex steps within the human metabolism.  This paper explores how human metabolism works by assessing advances in molecular biology and research in genetics, epigenetics and gerontology. Recent developments in these scientific disciplines shed light on the complexity of how human health is maintained and diseases are invoked. Public health bodies should be aware, interested and possibly contribute to the aforementioned areas of interest, as far as NCDs are concerned, and translate major developments in a way, that could be useful in improving population health.

Public health research needs for molecular epidemiology and to emphasize homeostasis - could the omnipotent endopeptidase inhibitor α-2-macroglobulin be a meaningful biomarker?

Public health authorities in low- and middle-income countries face dramatic challenges in handling rapidly increasing non-communicable diseases (NCDs), due to the epidemiological- and particularly nutritional transition. Among major reasons for the development of NCDs are smoking and alcohol, but overnutrition and obesity are also major threats to population health. Obesity is related to diabetes and cancer, but also has a genetic background. It is difficult to recommend a healthy nutrition. This is because of conflicting nutritional conceptions, and given the complexity of human metabolism understanding this topic can be difficult for the laymen.  Public health measures advocating physical activity and refraining from high intake of energy, sugar and soft drinks need to be enhanced by supporting the 'intrinsic motivation' to preserve a good health. The mission of public health should be to increase awareness about the complexity of human metabolism, and the involvement of genetic and epigenetics in health and diseases. To maintain homeostasis, means to keep an optimal relationship between catabolism and synthesis, seems to be of particular interest. Preconditions for this is, that public health institutions within the administration- and academic sector follow up developments in life science and molecular biology and conduct population-based research making use of molecular epidemiology, especially those related to key metabolic steps and maintenance of 'homeostasis', in balancing catabolism and anabolism. A prospective biomarker for this situation might be α-2-macroglobulin.

Quality of life and compliance among type 2 diabetic patients.

A cross-sectional study was conducted to explore the quality of life (QOL) and compliance among type 2 diabetic patients in Saraburi Province, Thailand. Compliance was assessed by evaluating dietary intake and life style patterns useful for diabetes patients to maintain health and prevent complications of the disease. A multistage sampling technique was used for selecting patients from 2 districts (Wihan Daeng and Nong Don) and subjects were classified into 2 groups according to a quality of life (QOL) score (good = 70, poor to moderate = 94) using WHOQOL-BREF-THAI criteria. Data were collected from September to December 2007 using a self-administered questionnaire. Simple descriptive statistics were used to provide basic information about the two groups and for analytical purposes the chi-square test and multiple logistic regression were applied. The majority (78.7%) of study participants were females. Most patients belonged to the age groups of either > 50 years (50%) or 40-49 years (36.6%). Bivariate analysis revealed socio-demographic factors were not significantly associated with QOL (p > 0.05). As far as compliance was concerned dietary control and drug intake were significantly associated with QOL (p < 0.05). Multivariate analysis indicated that overall compliance was associated with QOL (OR = 1.91, 95% CI = 1.02-3.57). We conclude that good QOL is significantly related to good compliance. Therefore, diabetic patients should be made aware that following the suggestions to prevent side effects of the disease and trying to stay healthy despite suffering from the disease will significantly improve their QOL.

Low birth weight infants born to HIV-seropositive mothers and HIV-seronegative mothers in Chiang Rai, Thailand.

The low birth weight (LBW) infant has a much higher risk of mortality and morbidity in infancy and early childhood. This study examined the effects of maternal HIV infection and other risk factors for LBW (< 2,500 g). A retrospective study of mothers who delivered at Mae Chan Hospital from 1997 to 2002 was conducted. Logistic regression was used to adjust for confounding factors. There were 266 infants born to HIV-seropositive mothers and 5,872 infants born to HIV-negative mothers. Low birth weight was significantly associated with maternal HIV status, gestational age, antenatal care, maternal age less than 20 years, and > 35 years. Maternal HIV positive status, young maternal age and gestational age were significant factors after adjusting for potential confounders. No significant effect of hilltribe on LBW was found. The results underline the need for nutritional surveillance and dietary counseling. HIV-seropositive women must receive early and continuing antenatal care for good pregnancy outcomes.

Dietary patterns and their association with the components of metabolic syndrome: A cross-sectional study of adults from northeast Thailand.

Background: Nutritional transition influences a shift in eating behaviour that is associated with a rise in the prevalence of non-communicable diseases (NCDs). Metabolic syndrome (MetS) comprises a set of NCD risk factors. This study aimed to investigate dietary patterns and to determine the relationship between dietary patterns and MetS and its components. Methods: A cross-sectional study was conducted among 468 healthy adults aged 35-60 years who were residents of a semi-urban district of one of the central provinces in the northeast of Thailand. A factor analysis identified dietary patterns based on the consumption of 21 food groups, which were assessed by using a semi-quantitative food frequency questionnaire. MetS was identified by using the harmonized criteria that were stipulated by six leading international organisations. The association between dietary patterns and MetS and its components were evaluated by multiple logistic regressions. The confounding factors adjusted in the model were age, sex, smoking status, physical activity, and medication intake. Results: Two dietary patterns were identified: a traditional pattern characterised by high intakes of sticky rice and animal source foods; a mixed pattern included high intakes of white rice and a variety of food groups. The two dietary patterns did not show any association with MetS. Participants in the highest tertile of the traditional pattern was significantly related to high triglycerides (adjusted OR = 1.74, 95% CI: 1.10-2.88), in comparison to those from the lowest tertile, whereas participants in the highest tertile of the mixed pattern was inversely associated with abdominal obesity (adjusted OR= 0.49, 95% CI: 0.30-0.81) than those in the lowest tertile. Conclusions: Adherence to a traditional dietary pattern among the northeast Thai adults, in the context of nutrition transition, was associated with high triglyceride levels while the mixed dietary pattern was inversely related to abdominal obesity.

Methylenetetrahydrofolate reductase (MTHFR) polymorphism (C677T) in relation to homocysteine concentration in overweight and obese Thais.

We analyzed the association between MTHFR (C677T) gene polymorphism with serum concentrations of homocysteine, folate, and vitamin B12 in 37 male and 112 female overweight/ obese Thai volunteers (BMI > or = 25.00 kg/m2), and compared them with 23 male and 90 female control subjects (BMI = 18.5-24.99 kg/m2). Statistically significant higher levels of serum homocysteine were found in the overweight/obese subjects than the control subjects (p < 0.05). Serum folic acid levels in the overweight/obese subjects were significantly lower than the control subjects (p < 0.05). When the data were grouped according to homocysteine concentration and MTHFR gene polymorphism, there were significantly higher homocysteine concentrations in the overweight/obese subjects than the control subjects in wild type gene polymorphism (CC) in the hyperhomocysteine group (homocysteine >10.0 mmol/l) (p < 0.05), but in genotype polymorphism (CC, CT, TT) there were lower folic acid and vitamin B12 concentrations in the overweight/obese subjects than in the control subjects. In the hyperhomocysteine groups, there was no significant difference in the frequencies of MTHFR (C677T) gene polymorphism between the overweight/obese subjects and the control subjects. Folic acid and gene polymorphism were found to be significantly related to the overweight/ obese and control groups in logistic regression analysis (p < 0.05). The results support the supposition that folic acid is more important than vitamin B12.

Community participation for thalassemia prevention initiated by village health volunteers in northeastern Thailand.

The study was conducted to assess the achievement of a thalassemia screening program at a community level supported by village health volunteers (VHVs) of 2 subdistricts in the northeast of Thailand. One subdistrict served as the intervention and the other as the control area. A training program was organized for the village health volunteers from the intervention area. Essential information about the risk and danger of thalassemia was given to the participants who wanted to have children in the community as well. Of the 206 individuals who wanted to have children living in the intervention area, 190 (92.2%) agreed to undergo screening. Of the 196 individuals within the control area, only 26 (13.3%) voluntarily participated in the screening tests. Attitude toward prevention and knowledge about the disease improved significantly in both areas, but the differences between the scores were statistically significantly higher for individuals living in the intervention area.

Serum homocysteine, B12 and folic acid concentration in Thai overweight and obese subjects.

This study investigated levels of serum homocysteine, vitamin B12, folic acid, vitamin B6 and vitamin C, in 37 male and 112 female overweight and obese Thai volunteers (body mass index; BMI > or = 25.00), and 23 male and 90 female normal-weight Thai volunteers, who came for a physical check-up at the Out-patient Department, General Practice Section, Rajvithi Hospital, Bangkok from March to October of 2000. Data included anthropometric measurements and waist/hip ratios. All anthropometric variables, except height, were significantly higher for the overweight subjects than for the normal subjects. Statistically significantly higher levels of serum homocysteine were found in the overweight subjects. Serum homocysteine concentrations in overweight and obese males were significantly higher than in overweight and obese females. Serum folic acid and vitamin C in the overweight and obese were found to be statistically significantly lower than in the control subjects. No statistically significant difference in vitamin B12 was found in the overweight and obese subjects compared with the normal control subjects. The medians of serum folic acid and vitamin C concentrations for the overweight and obese males were significantly lower than those of the overweight and obese females. A negative correlation was found between serum folic acid and homocysteine concentrations in all overweight and obese subjects. A significant negative correlation between serum folic acid and vitamin B6 was observed in both male and female overweight and obese subjects. The results of the investigation suggest that homocysteine levels in overweight and obese subjects seem to be caused by insufficient dietary folic acid intake and probably not by B12 deficiency.

The effect of cigarette smoking on ceruloplasmin and C3 complement: risk of cardiovascular disease (atherosclerosis).

Serum ceruloplasmin, C3 complement and albumin in 119 male smokers and 65 male non-smoker; from a military unit in Bangkok were investigated in this study. The serum ceruloplasmin concentration was found to be significantly higher in smokers than in non-smokers. However, the serum albumin concentration in smokers was statistically significantly lower than in non-smokers. Significant associations were also found between ages, albumin levels and the quantity of cigarettes smoked. There was a significant positive correlation between serum ceruloplasmin and C3 complement concentrations. An association between the quantity of cigarettes smoked and albumin was also found, as well as a significant relationship between smoking and the quantities of cigarettes smoked to serum ceruloplasmin levels when smoking and the quantity of cigarettes smoked were taken as independent variables, and the serum ceruloplasmin levels as a dependent variable. This might suggest that high concentrations of the acute-phase protein, i.e. ceruloplasmin, might constitute a risk of developing atherosclerosis or cardiovascular disease in smokers.

Serum copper, zinc, ceruloplasmin and superoxide dismutase in Thai overweight and obese.

The serum copper, selenium, ceruloplasmin, superoxide dismutase (SOD) (specific activities of antioxidant enzymes), anthropometric measurements, including waist/hip ratio 51 male and 190 female overweight subjects (body mass index (BMI) > or = 25.0 kg/m2) compared with a 26 male and 83 female control group (BMI = 18.5-24.9 kg/m2) Thai volunteers who attended the Out-patient Department, General Practice Section, Rajvithi Hospital, Bangkok, for a physical check-up from March to October, 1998, were investigated. There was no age difference between the overweight group and the controls. All of the anthropometric variables, except the height of the overweight group, were significantly higher than those of the normal subjects. The medians of weight and waist/hip ratio of overweight and obese males were significantly higher than those of overweight and obese females. Serum ceruloplasmin, copper were statistically significantly higher in overweight subjects than in the controls. However, serum zinc and superoxide dismutase activity in the overweight group were found to be lower than in the control group. Higher serum ceruloplasmin, copper, zinc and superoxide dismutase activity were shown in the female overweight group than in the male overweight group. Ceruloplasmin was found to correlate positively with copper concentration but negatively related with superoxide dismutase enzyme activity. A negative correlation was found between serum copper and zinc concentrations in both sexes of the overweight and obese subjects. Low SOD activity found in the overweight and obese subjects might be caused by low zinc intake.

B vitamins, vitamin C and hematological measurements in overweight and obese Thais in Bangkok.

The dynamic changes of socio-economics leading to the industrialisation of countries are known to affect lifestyle and nutritional behaviours of the population. Review of the literature on the prevalence of obesity showed increasing numbers of the overweight and obese during the past decade. However, information on health and nutritional status of the obese in Thailand has not been widely publicized. This study reveals the vitamin status and hematological picture in 270 overweight and obese Thais in Bangkok, Thailand, compared with 175 normal subjects. No statistically significant differences in haemoglobin and hematocrit were observed in the overweight compared with the control subjects. The prevalence of anaemia was 9.8 per cent among male and 17.2 per cent among female overweight and obese subjects compared with 2.6 per cent and 21.2 per cent in male and female normal controls using the cut-off point of haemoglobin concentration as an indicator of anaemia. Prevalence of hypertension was exhibited in both male and female overweight and obese subjects. Even if there were no statistically significant differences in vitamin B1, B2 and B6 in overweight and obese subjects compared with the controls, high percentages of vitamin C and vitamin B2 deficiencies were observed. Vitamin B2 deficiency was detected in 19.7 per cent of overweight and obese males as well as in 28.7 per cent of overweight and obese females using glutathione reductase activity coefficient (alpha EGR) < 1.5 as the cut-off point. However, clinical signs of vitamin B2 deficiencies were rare. There was also a high percentage of vitamin C (antioxidant vitamin) deficiency in 51.5 per cent of the overweight and obese subjects and 41.7 per cent of the controls, respectively. The results suggest more attention should be paid to health study and nutritional problems for the overweight and obese population, especially concerning vitamins and oxidative stress. Further research is still needed in these aspects.

Health status of diabetes type 2 patients in Thailand contradicts their perception and admitted compliance.

A nationwide data set about the health status of diabetes mellitus type 2 (DM) patients and a questionnaire of a sub-sample of the DM patients about their know-how, behavior and perception about health care had been re-assessed. Laboratory results revealed that in average 70% of the patients had been over nourished, over 50% had abnormal cholesterol-, over 55% had high triglyceride levels and 51% had high density lipid (HDL) values below 45 mg/dl. Sixty percent of patients had glycated hemoglobin (HbA1c) levels over 7%. About 60% of study participants answered a questionnaire. In contrast to the laboratory findings about 90% claimed to take the medicine as the doctor advised, 60% said that they adjusted their food intake as advised and more than 80% said that they know well how to take care of themselves. They were only superficially informed about the complications of DM. Almost 95% were satisfied with the health service they receive and over 70% were satisfied with their health status. The results are discussed in connection with the need to control DM on the basis of primary health care (PHC). It is argued that the assessment of health programs solely through questionnaires might be misleading, if the findings are not confirmed by clinical and biochemical parameters.

Relationship of tobacco smoking with serum vitamin B12, folic acid and haematological indices in healthy adults.

OBJECTIVES: To investigate the effects of tobacco smoking on serum vitamin B12, folic acid and haematological parameters in healthy Thai smokers and non-smokers. DESIGN: Cross-sectional study of smokers and non-smokers in a military unit in Bangkok, Thailand. SETTING: A military unit in Thailand. SUBJECTS: One hundred and twenty-three male smokers from a military unit in Bangkok, who participated voluntarily in the study, were investigated. Sixty-six male non-smokers from the same unit were selected as controls. Fasting blood samples were collected for investigation of vitamin B12, folic acid and haematological variables. RESULTS: The serum folic acid concentration of smokers was lower than that of non-smokers, but was not statistically significantly different. Haemoglobin was lower in smokers than in non-smokers; 16.3% of smokers were anaemic compared with only 3.0% of non-smokers. Anaemia was not related to folate deficiency. The white blood cell count was found to be higher in smokers than in non-smokers. CONCLUSION: The results of this study suggest that there were low serum folic acid concentrations in smokers compared with non-smokers, which might contribute to the development of vascular and cardiovascular diseases. The higher white blood cell count might be indicative alterations in the immune functions of smokers.
