Studies were carried out from June 1974 to May 1975 on the socio-economic status, health and nutritional status of the people in 4 villages, in the irrigation area of the Nong Wai Pioneer Agricultural Project of Khon Kaen Province, Northeast Thailand. The result obtained were compared with those in 2 non-irrigated villages in the same province, in order to identify the health and nutritional problems which might arise during the water resource development in the irrigation area. It was found that in the irrigated villages 90% of the peoples were farmers, while in the non-irrigated villages all were farmers. The socio-economic status of the people in the irrigated villages was much better than those in the non-irrigated ones. The income per family in the former was about three times greater than that in the latter. In the study of the health conditions of the villagers, the vulnerable age group including pre-school children under 7 years of age and school children in the elementary school class 1 and class 2, aged 7-9 years old, served as subjects for investigation. Haematological and physical examinations revealed many children with mild to moderate anaemia, vitamin B2 deficiency and a few cases of hepatomegaly. Anaemic children were found to be more prevalent in the non-irrigated villages than in the irrigated area. The overall parasitic infection rates in children in the irrigated and non-irrigated villages were similar with respect to severity of the infection. Hookworm infection, opisthorchiasis, strongyloidiasis and giardiasis were the leading parasitic infections, while amoebiasis was rare. Ascariasis and trichuriasis were not found. However, the first two helminthic infections had a low grade of intensity. The nutritional status of pre-school children, showed that there were more children with good growth in the irrigated villages than in the non-irrigated one. Serum proteins, albumin and globulin, and urinary urea nitrogen-creatinine ratio revealed normal findings indicating that the children had sufficient protein intake. The results of the urinary hydroxyproline-creatinine index suggested that many of the children in both groups of the villages were at marginal malnutrition status. Surveys on domestic animals including cattle, buffaloes, pigs, and field rats revealed no important zoonotic diseases except leptospirosis in a few rats. Some fish were found to harbour metacercariae of Opisthorchis viverrini, while some snails were positive for cercariae of O. viverrini, Schistosoma spindale, and Echinostoma malayanum. The overall findings indicated that the water resource development by establishing better irrigation, resulted in an improved socio-economic and nutritional status among the villagers, but health conditions and associated parasitic diseases and some nutritional deficiency still existed in the children. However, the findings from this study provide only preliminary data concerning the socio-economic status, health, and nutritional status of the villagers in the irrigation area...

The relationships between S. haematobium, hookworm, malaria, hemoglobin level, splenomegaly, and hepatomegaly before and 8 months after treatment with a single dose of metrifonate or praziquantel were studied in Kenyan primary schoolchildren in an area where anemia, S. haematobium, and hookworm are common and malaria is holoendemic. Children with light to moderate S. haematobium infection were examined (Exam 1), assigned at random to groups receiving placebo (PL, n = 104), metrifonate (MT, n = 103, dose 10 mg/kg body weight) or praziquantel (PR, n = 105, dose 40 mg/kg body weight), treated, and examined 8 months later (Exam 2). At Exam 2, 62% of the MT group still passed S. haematobium eggs vs. 13% in the PR group. Egg reduction rates were substantial in both groups, but greater in the PR group; geometric mean egg counts in both groups were very low. Prevalence and intensity in the PL group had not changed between exams. Hookworm egg counts were significantly reduced in the MT group (59% egg reduction rate); malarial infection had increased in all 3 groups, presumably due to the long rainy season between exams. Hookworm egg count was the most significant predictor of initial hemoglobin level, followed by S. haematobium egg count and presence of malarial infection. Treatment with a single dose of MT or PR can produce substantial decreases in S. haematobium infection 8 months later.

Schistosomiasis japonica and soil-transmitted helminthiasis are endemic parasitic diseases in the People's Republic of China (PR China). As very few studies have reported on the distribution and interaction of multiple species helminth infections, we carried out a comparative study of households in a rural village and a peri-urban setting in the Dongting Lake area of Hunan province in November and December 2006 to determine the extent of single and multiple species infections, the underlying risk factors for infection, and the relationships with clinical manifestations and self-reported morbidity. In each household, stool samples were collected and subjected to the Kato-Katz method for identifying Schistosoma japonicum, Ascaris lumbricoides, hookworm and Trichuris trichiura infections. Clinical examinations were performed and questionnaire surveys conducted at both household and individual subject levels. Complete parasitological, clinical and questionnaire data were obtained for 1,298 inhabitants of the two settings. The overall prevalences of single infections of S. japonicum, A. lumbricoides, hookworm and T. trichiura were 6.5%, 5.5%, 3.0% and 0.8%, respectively; the majority of the infections were of light intensity. We found significant negative associations between wealth and infections with S. japonicum and A. lumbricoides. Clinical manifestations of splenomegaly, hepatomegaly and anaemia were prevalent (9.0%, 3.7% and 10.9%, respectively), the latter two being significantly (P<0.05) associated with schistosomiasis. Self-reported symptoms were more common among females but there was considerable under-reporting in both sexes when relying only on spontaneous recall. Our findings may guide the design and targeting of a more equitable, comprehensive and integrated parasitic disease control programme in Hunan province and in other areas of PR China.

The occurrence and spatial distribution of intestinal helminth infection in children is fairly well understood. However, knowledge on how helminth infections govern intestinal morbidity is scarce. We conducted a cross-sectional study to assess and quantify the relationship between single and multiple species helminth infection with clinical and self-reported morbidity indicators and nutritional status in Champasack province, southern Lao People's Democratic Republic (Lao PDR). A random sample of 1313 children, aged 6 months to 12 years, from villages in nine rural districts were enrolled and examined for helminth infection using duplicate Kato-Katz thick smears. Morbidity was assessed by self-reported symptoms, coupled with clinical examination and appraisal of nutritional status and anaemia. Bivariate and multivariate logistic regression was employed to study associations between helminth infection and morbidity indicators and anaemia. We found considerable morbidity among the surveyed children, including hepatomegaly (13.7%), pale conjunctiva (13.2%) and abdominal pain (10.4%). Anaemia was recorded in 60.4% of the children, whilst signs of stunting and low body mass index (BMI) were observed in 49.8% and 33.3% of the surveyed children, respectively. Hookworm and Opisthorchis viverrini were the predominant helminth species with prevalences of 51.0% and 43.3%, respectively. The prevalence of Schistosoma mekongi in the surveyed children was 5.6%. Multiple species helminth infections were recorded in 40.4% of the study cohort. Morbidity was associated with specific helminth species infection (e.g. S. mekongi with hepatomegaly; adjusted odds ratio (aOR): 9.49, 95% confidence interval (CI): 2.07-43.51) and multiparasitism (e.g. two or more helminth species with abdominal pain; aOR: 2.40, 95% CI: 1.46-3.93). Anaemia was associated with hookworm infection (aOR: 1.64, 95% CI: 1.16-2.34) and multiparasitism (aOR: 1.64, 95% CI: 1.18-2.29). Low BMI was associated with O. viverrini infection (aOR: 1.68, 95% CI: 1.14-2.49) and multiparasitism (aOR: 1.42, 95% CI: 1.01-2.00). The multiple strong associations reported here between helminth infections (single or multiple species) and intestinal morbidity among children in rural parts of southern Lao PDR call for concerted efforts to control helminth infections, which in turn might improve children's health and development.
