RESUMEN
This study aimed to 1) compare levels of high sensitivity c-reactive protein (hs-CRP), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-alpha) between overweight Thais and apparently healthy controls, and 2) investigate the association between serum hs-CRP, IL-6, and TNF-alpha levels and other biochemical parameters. A total of 180 health-conscious adults aged 25-60 years, who resided in Bangkok, participated in this study. No significant difference was found in age and sex between the overweight subjects and controls. Serum levels of hs-CRP, IL-6, TNF-alpha, glucose, lipid profile, body mass index (BMI), waist circumference (WC), hip circumference (HC) and waist hip ratio (WHR) were determined in these volunteers. The mean levels of white blood cells (WBC), uric acid, total cholesterol (TC), triglyceride (TG), and hs-CRP were significantly higher in the overweight subjects than those in the controls, whereas high density lipoprotein-cholesterol (HDL-C) values were significantly higher in the controls than the overweight subjects (p < 0.05). Hs-CRP levels were significantly positively correlated with levels of TG, BMI, WC, HC and WHR. HDL-C levels were significantly negative correlated with hs-CRP levels. In conclusion, the prevalence of elevated serum hs-CRP levels was higher in overweight subjects than controls. However, more data in larger and other population groups are needed to confirm this study.

From March to July 1998 the infection rates of 732 children aged below 15 years were assessed. The investigation was conducted in selected villages of the Bolikhamxai Province in Lao PDR. Socio-economic conditions and behavioral pattern were studied. The three soil-transmitted helminths, Ascaris lumbricoides, Trichuris trichiura and hookworm were found with prevalence rates of 67.14, 17.49 and 12.83%, respectively. Infection rates with other intestinal parasites were negligible. Of the children investigated, 56.7% harbored one and 20.45% more than one parasite. Except for hookworms, no statistically significant differences were found between genders. The probability of being infected with A. lumbricoides is associated with living in mountainous areas. For hookworms, infection is associated with staying in the plains. A river in the vicinity of the village is linked with the probability of being infested with Trichuris trichiura. Not to belong to a family with the ability to own expensive items increases the probability by almost two times of getting infested with A. lumbricoides. Unhygienic behavioral factors were important in increasing the probability of suffering from A. lumbricoides and T trichiura infection. Behavioral factors did not seem to be related to hookworm infections. It was concluded that after mass treatment, besides promoting the construction of toilets, it is also important to improve personal hygiene so that a lasting impact on the infection rate of the most prevalent parasites in Lao PDR could be achieved. Measures to control parasitic infections do not have to be postponed until a marked improvement of the economic situation has occurred.

The weight, height and body mass index (BMI), including waist/hip ratio, serum leptin and hematological parameters of 48 male and 166 female overweight (BMI > or = 25.00) Thai volunteers who came for a physical check-up at the Out-patient Department, General Practice Section, Rajvithi Hospital, Bangkok during the period March-October 1998, were investigated. There were statistically significantly higher levels of serum leptin, mean corpuscular mean corpuscular hemoglobin concentration (MCHC) and mean corpuscular volume (MCV) in the overweight than in the control subjects. The median serum leptin concentration in overweight subjects was 19.6 (2.0-60.0 ng/ml) compared with 9.0 (range 1.0-30.0 ng/ml) in the control subjects (p < 0.001). The medians of leptin in overweight and obese males were significantly higher than those of overweight and obese females. 66.7% (32 out of 48) of overweight and obese males were found to have elevated leptin levels, while 87.3% (145 out of 166) were found in overweight and obese females. Anemia was found in 18.7% of female overweight and obese subjects, using hemoglobin as an indicator. Significant associations were found between weight, height, BMI, waist, hip, waist/hip ratio, hemoglobin, hematocrit, and serum leptin in both male and female overweight subjects. A negative correlation was found between serum leptin and hemoglobin, and hematocrit in both overweight and obese subjects.

Under the supervision of the central and local health authorities, a pilot project was conducted in four villages in the Luangprabang Province, Lao PDR. The objective of the project was to test different regimes to supplement females with oral iron preparations to reduce iron deficient anemia (IDA) and control iodine deficiency disorders (IDD) in school children. Compared with iron sulphate tablets, iron fumerate tablets were well accepted and good compliance results were achieved. Hemoglobin concentration improved only in the group of females taking iron fumerate tablets. The goiter rate decreased from approximately 90% to about 45% for school children, regardless of whether iodine salt were used by their families or whether iodine capsules were used to treat the children. The latter attempt was hampered by the fact that also in the control village iodine fortified salt was used. This was due to a governmental attempt to control IDD nation-wide. Therefore, also in the control village a significant decrease in the goiter rate was observed.

A project to promote the health and nutritional status of women and pre-school children was started from 1995 to 1997 in three villages in Suvannakhet Province, Lao PDR. One village served as control. In 1995, for the baseline survey, 456 females, and in 1997, for the final evaluation, 363 females from the four villages volunteered for further investigations. An attempt was made to involve all females in the reproductive age residing in the villages. At the same time also the nutritional status of 321 and about 540 randomly selected pre-school children respectively was also assessed through physical examination and anthropometric measurements. Intervention measures included introducing growth charts and taking regular anthropometric measurements of women in the reproductive age and of pre-school children. Training in nutritional aspects such as giving colostrum to new-borns, prepare proper weaning food and supplementary feeding, animal-raising and home gardening was also introduced and provided to health personnel, village leaders and in women clubs. Special attention was given to the control of acute infectious diseases. The conventional EPI program was enforced as well. Health education in matters of mother and child health care was also provided. The proportion of undernourished women was rather high at about 15%. For pre-school children, the proportion of wasting was around 5%, and of stunting 50% and above. Intervention did not improve the nutritional status either of the women or of the children. It was concluded that the time span of two years is too short for a decrease in the proportion of undernourishment to be observed. An improvement was achieved for some indicators of mother and child health care. This seems to indicate the population's willingness to follow suggestions to improve their health. Most probably, if attempts to improve the nutritional status were continued, an improvement in this aspect could also be observed, if the population can be encouraged to take actions and develop initiatives by themselves.

An intervention project focusing on the health of women in the reproductive age was conducted in three districts of Khon Kaen Province, northeast Thailand between 1991 and 1996. Main emphasis was placed on improving reproductive health, the nutritional status including the iron deficiency anemia (IDA) as well as iodine deficiency disorders (IDD), and the parasitic diseases liver fluke (Opisthorchis viverrini) and hookworm. For implementation a community based Primary Health Care approach was used including the training of health officials in health matters, primary health care workers and villagers as well as enhancing health education and the dissemination of health information. The health delivery system was encouraged to take appropriate actions such as in the treatment of parasitic diseases and the control of IDA and IDD. Monitoring was done on a regular basis. The outcome of the project was assessed by comparing baseline data compiled from a random sample of the target population with the results of the final evaluation. An attempt to compare results obtained from villages within and outside of the project area failed most probably because of spill over effects. A number of important indicators on family planning and mother and child health care improved during the time the project was implemented; this included practising family planning, and participation in antenatal care. Also the proportion of females becoming pregnant for the first time when 20 years or older increased. Child-raising also improved in that almost all females gave colostrum to their babies by this time. Almost 75% of the women breast-fed their children. Improvements occurred in the nutritional status as far as the micronutrients iron and iodine were concerned, however the overall nutritional status of females did not change, but a rather high proportion of females were found to be overnourished. The project failed in reducing abortion and the proportion of females becoming pregnant when they are 18 years old or younger. It was also not possible to improve the usage of postnatal care. As anticipated, the results achieved so far are most suitable in serving as a training ground and providing a favorable example to improve family planning, mother- and child health care, and also the general health of females in the region, particularly in neighboring countries such as Lao PDR, Cambodia and Vietnam.

The specific activities of antioxidant enzymes, [eg superoxide dismutases (SOD), glutathione peroxidase (GPX) and catalase (CAT)], anthropometric measurements, including waist/hip ratio of 48 male and 167 female overweight persons (body mass index (BMI) > or = 25.0 kg/m2) compared with a 26 male and 80 female control group (BMI = 18.5-24.9 kg/m2) of Thai volunteers who attended the Out-patient Department, General Practice Section, Rajvithi Hospital, Bangkok, for a physical check-up during March-October, 1998, were investigated. There was a slightly significant difference between the median age of the sexes. The medians of height, weight, and waist/hip ratio in males were significantly higher than those in female overweight and obese subjects. The median of arm circumference (AC), mid arm muscle circumference (MAMC) in males was significantly higher than those in female overweight and obese subjects (p < 0.05). The prevalences of hypertension based on systolic and diastolic blood pressure of > or = 160/> or = 95 mmHg, were 8.3% and 37.5% for males and 5.4% and 18.6% for females, respectively. There was no significant difference between the median of antioxidant enzymes (SOD, GPX and CAT) between the sexes. No significant differences in the antioxidant enzymes in male overweight/obese persons and normal controls were presented, whereas antioxidant enzymes in female overweight/obese persons were statistically lower than in control females (p < 0.05). A significantly higher SOD, GPX, and CAT status was observed in normal subjects compared with overweight/obese subjects (p < 0.01). A higher prevalence of SOD < or = 2,866 U/gHb, GPX (< or = 15.96 U/gHb in females was found, compared with males. A high percentage of lower catalase (CAT < or = 19.2x10(4) IU/gHb) was found in both sexes (64.5% in males and 64.5% in females). In obese subjects (BMI > or = 30.0 kg/m2), there were significantly positive relationships between systolic and diastolic blood pressure, systolic blood pressure and waist/hip ratio, and SOD could be related to weight, BMI as well as GPX and CAT, whereas the opposite result was observed for age and SOD.

Intestinal helminths are a very common but still rather unrecognized public health problem. An attempt was undertaken to control the three important parasites, ie Ascaris, Trichuris and hookworm. Two villages in Vientiane Province in Lao PDR were selected, one as an intervention and the other as control village. Intervention measures started by providing mass treatment against Ascaris, Trichuris, hookworm and other intestinal parasitic infections in both villages. Health education and other intervention measures were implemented in the intervention village, which significantly influenced the re-infection rates in this village. These achievements were not due to an improvement of the availability of toilets or personal hygiene alone but more to the villagers' improved understanding of the route of the parasitic infections. It was concluded that intervention methods should be directed more towards particular age groups. Particular attention should be paid to control parasitic infections among females.

The aim of the project was to improve the knowledge and attitude towards birth spacing by training the villagers in the selected villages of Vientiane Province in Lao PDR in family planning, providing them with the various family planning methods, and improving antenatal (ANC) and postnatal (PNC) care in the villages. Throughout the province, traditional birth attendants (TBA) were trained on several occasions during the project period. There were clear indications that reproductive health improved between 1995 and 1997. Considerable improvements were observed in the percentage of women making use of ANC and practising birth spacing by using some form of contraception or other. The most common methods used were contraceptive pills and injectables. In the case of child mortality a slight decrease was found in the percentage of women having their first pregnancy below the age of 18 years. A still unsolved problem is the high number of abortions.

In 7 villages on the foothills of the Houayxai district of the Bokeo Province in Lao PDR between midyear 1995 to midyear 1997 an attempt was made to test the acceptability and use of DDT impregnated bed nets as well as environmental and behavioral risk factors. About 380 women between 15 to 45 years old and their children in the age range of 1 to 14 years had been studied. A pre-tested questionnaire had been applied and blood from women and children was taken from the finger prick and a conventional thick and thin blood smear was performed, fixed Giemsa stained and examined for malaria parasites. DDT (dichlorodiphenyltrichloroethane) impregnated mosquito nets were distributed in the intervention villages. The availability of mosquito nets increased statistically significant from approximately 50% to 70% for all family members in the intervention area between 1995 and 1997 and statistically significant decreased in the control area from 79% to 45.1%. There was a statistically significant decrease in malaria attacks as claimed by the females for the intervention area but not for the control villages. The proportion of positive blood smears did decrease overall for women and children in between 1995 to 1997. Occupation, location of the house and use of mosquito nets had been determined as the most important risk factors.

Endemic goitre has re-emerged in Thailand. This is particularly dangerous for children since iodine deficiency disorders (IDDs) might negatively influence their intellectual and mental development. In order to assess the situation, the iodine content of breast milk was determined and a method is proposed on how to monitor IDDs in lactating mothers later on. Seventy-five lactating women aged from 15 to 45 years, from 12 villages of 3 districts, namely Chumpae. Srichompu and Pupaman within the mountainous areas of Khon Kaen province, Northeast of Thailand were investigated. The breast milk from 46.7 per cent of mothers was found to be below recommended standards. In addition, 52.0 per cent of the women investigated had low urinary iodine excretion. The risk of women with low iodine excretion was 15 fold higher in comparison to women with sufficient iodine excretion to provide breast milk for their babies with insufficient iodine content. It is concluded that urinary iodine excretion can be used to monitor the IDDs in lactating mothers.

The study was carried out from September to November 1997 in Phrae Province of northern Thailand. A total of 95 adult patients with Opisthorchis-like ova in their stools were randomly treated with two different manufactured Praziquantels. Group 1, consisting of 49 patients, received a single dose of 40 mg per kg Praziquantel manufactured by the Thai Government Pharmaceutical Organization. Group 2 (46 patients) received Biltricide at the same dosage. Haplorchis taichui, H. yokogawai, Echinostome spp., O. viverrini, Taenia saginata and Enterobius vermicularis were expelled in the stools after treatment. Minute intestinal flukes were detected in 64% of patients. O. viverrini was found in lower proportion of 17%. By formalin-ether concentration examination one stool specimen from each patient, the cure rate in both groups on the 30th day of treatment was 100%. The side effects of the two different Praziquantel treatments were mild with no significant difference. Praziquantel, regardless of its manufacture, proved effective against O. viverrini and other minute intestinal flukes (H. taichui, H. yokogawai and Echinostome spp).

To improve the health and nutritional status of school children in an area of iodine deficiency disorders (IDD) by means of different iodine fortifications in salt, fish sauce and drinking water, anthropometric assessment for nutritional measurement, including hematological status, were performed. There was a significant difference in the weight and height of the children from the four schools investigated, before and after supplementation in each school. The prevalence of anemia (as indicated by hematological measurement) and iodine deficiency (as indicated by urinary iodine concentration in the children from the four schools) were assessed and compared before and after iodine supplementation; a decrease in prevalence was found in all school children, however, serum ferritin did not change before and after supplementation.

Serum vitamin B12, folic acid, ferritin and haematological variables were investigated in six hundred and seven women from 12 villages of 3 districts namely Chumpae, Srichumpu and Pupaman of Khon Kaen province, Northeast Thailand within the age range of 15-45 years. The cut-off point of haemoglobin concentration < 12 g/dl was applied for defining the normal and anaemic group (17.3%). The result showed that the concentration of ferritin, folic acid and vitamin B12 in the anaemic group were less than that of the normal group. Forty six out of 607 women or 7.6 per cent were found to be undernourished and 27.2 per cent of females were overnourished. The prevalence of deficiencies of vitamin B12, folic acid and ferritin were 6.3 per cent, 4.3 per cent and 12.5 per cent respectively.

Three hundred and fifty-five individuals, 152 males and 203 females, aged between 30 and 74 years, were randomly selected in a two stage selection process from rural communities in three districts of Khon Kaen Province, Northeast Thailand. The prevalence of impaired glucose tolerance (IGT) and non-insulin dependent diabetes mellitus (NIDDM) in the rural area of Northeast Thailand were measured. In addition, the validity of the urine stick and fasting blood sugar as screening tools against the two hours glucose loading test as golden standard were determined. The survey was conducted in July 1995. The glucose loading test was performed on 277 individuals. IGT and NIDDM were classified according to current World Health Organization suggestions. Prevalence rates for IGT were 18.1 per cent and for NIDDM 11.9 per cent. No difference was found between males and females, also when controlled for age. NIDDM prevalence increased with age but IGT rates already were high in the younger age groups. This finding suggests that IGT precedes NIDDM in Thailand. The validity of the urine stick as a screening tool in communities was insufficient, with a sensitivity of less than 20 per cent. When using fasting blood sugar as a screening test, the sensitivity was close to 44 per cent and the specificity 90 per cent. It is concluded that the urine stick is not a useful screening tool and the method of using blood sugar concentrations for screening have to be improved before it can be applied within communities.

The nutritional and health status of road sweepers in Bangkok was investigated. Fifty-seven males and one hundred thirty-four females from 10 districts were selected for the study. The districts were sampled as cluster at random. From each district selected about 50% of road sweepers volunteered to participate in the investigation. Through questionnaires the age, marital status, place of origin, drinking and smoking habits were assessed. Anthropometric measurements, blood pressure and the lipid profile of these subjects were determined. According to a physical check-up and X-rays taken, all individuals investigated were apparently healthy. The age of the study group varied between 26 and 57 years. The median for the males was 47 years and for the females 37.5 years. Almost all the road sweepers were married. Smoking and alcohol drinking was widespread. Over- and undernutrition was found among the group investigated. 26.3% of the males and 1.5% of the females were undernourished. According to their systolic values, 15.8% of the males and 6.7% of the females were suffering from hypertension, and 38.6% of the males and 15.7% of the females had hypertension according to their diastolic values. 58.2% of the females and 29.3% of the males were overnourished. 57.9% of the males and 59.7% of the females had cholesterol levels above 200 mg/dl. Pathological values of LDL cholesterol were determined in 26.3% of the males and 28.4% of the females. The habit of consuming tonic drinks was widespread among the workers. The study concluded that behavior risk factors are highly prevalent in the group of workers belonging to the lower socio-economic class. Further investigations are presently being undertaken to study the after-effects of air pollution among this group of workers. The results will be subsequently reported in future publications.

The risk of developing liver cirrhosis, hepatoma (HCC) and bile duct carcinoma (BDC) have been associated with homozygous alpha 1-antitrypsin (AT) deficiency especially linked to the Z allele. While the association between liver cancers and AT deficiency remains debatable, the risk of adult AT deficiency carriers to develop liver cirrhosis has not been assessed quantitatively. Liver cancers and liver diseases with subsequent liver cirrhosis are highly prevalent in tropical countries such as Thailand and heterozygous AT phenotypes are rather common in this country as well. The aim of this study was to assess the risk of developing liver cirrhosis, HCC and BDC by means of case-control studies with Thai patients and controls in connection with AT deficiency. For hepatitis, HCC and BDC to association with AT deficiency was detected. Carriers of PiMZ phenotype in Thailand have a high risk to develop liver cirrhosis (odds. ratio of 10.8, 95% confidence interval = 1.3-88.1). Patients with predisposing diseases should be screened for Pi phenotypes so that rigorous measures to combat the occurrence of liver cirrhosis can be implemented.

Serum vitamin B12, folic acid, ferritin and haematological variables were investigated in eighty-seven male and nineteen female construction site workers in Bangkok. Haemoglobin concentration, haematocrit and MCHC were found to be higher in male than in female workers. Serum ferritin was slightly higher in males than in females. Serum B12 was found to be higher in male than in female workers and serum folic acid level were significantly higher in female than in male workers. Vitamin B12 deficiency was found in 2.3 per cent and folic acid deficiency in 6.9 per cent of the male workers. Serum vitamin B12 and folic acid levels were normal for female workers. The adequate serum levels of vitamin B12 and folic acid might be the result of the habit of the workers to consume tonic drinks which contain glucose, caffeine, and vitamins especially vitamins B6, and B12.

Methods of iodine fortification were tested among women of child bearing ages in four villages of Khon Kaen province, an endemic area of goiter in northeast Thailand, Ban Wang Pa Dum, Ban Pa Klauy and Ban Non Chart received iodine fortified in fish sauce, salt and drinking water respectively, whereas, Ban Non Sa-aad served as a control village. Urine iodine concentrations were investigated before supplement and after three and six months of the experimental period. Three months after supplement, urine iodine levels of villagers from Ban Non Chart and Ban Non Sa-aad were higher than those of Ban Wang Pa Dum and Ban Pa Klauy. Six months later, subjects from Ban Wang Pa Dum and Ban Pa Klauy who had received fortified fish sauce and iodinated salt respectively had significantly higher urine iodine concentrations than those of the other two villages. The result implied that fortified fish sauce and iodinated salt were well accepted by the villagers. However, fortified fish sauce might be the best and most feasible method because villagers use fish sauce more constantly in cooking and salting dishes.
