Trend of Malaria Incidences and its Association with Rainfall in Kalahandi District of Odisha, India

In Odisha, Kalahandi is one of the most exposed and vulnerable districts to malaria incidences due to its poor socioeconomic condition and extreme climate. The study aimed to explore the temporal characteristics of malaria incidences in Kalahandi and to identify its relationship with rainfall for the period from 2011 to 2018. Out of the total blood films examined, 8.84% were found positive in Kalahandi between 2011 and 2018. Plasmodium falciparum is the most dominant species accounted 88.3% of the total cases. Very high mean annual parasitic index (API) >15 is recorded throughout the study years. The highest incidences are recorded in the monsoon season followed by postmonsoon. The correlation value of the annual blood examination rate with P. falciparum, Plasmodium vivax, and API has shown a very high positive correlation. Rainfall shows a (+) correlation with malaria incidences in the cold (0.47) and hot seasons (0.01) and (−) correlation in the monsoon (−0.54) and postmonsoon season (−0.54).

Iodine deficiency in urban slums of Bhubaneswar.

OBJECTIVE: The present study aimed at assessing the population prevalence of goiter and iodine deficiency in school children of 6-12 yr living in urban slums of Bhubaneswer, the capital city of Orissa. METHODS: A cross-sectional study was performed using the 30-cluster sampling methodology and surveillance methods for iodine deficiency as recommended by WHO/ICCIDD/UNICEF. The total goitre rate (n=1248), urinary iodine concentration (UIC) (n=411) and iodine content of edible salt (n=368) were measured. RESULTS: The goitre prevalence was 23.6% (grade 1=18.9%, grade 2=4.7%) with no significant gender variation. Goitre prevalence was significantly higher in children of 10-12 yr (P=0.012) and scheduled caste and tribe (P=0.003). Median urinary iodine concentration was 50.0 microg/l with 85.7% of children having values less than 100 microg/l, indicating as biochemical iodine deficiency. Median UIC was inversely in association with gradations of goitre. Children of 10-12 yr and scheduled caste/tribe communities had significantly higher median UIC (P=0.001) than their counterpart peers. About 51% of children were consuming salt having stipulated iodine content of 15 ppm. CONCLUSION: The study indicates moderate iodine deficiency in the population, despite a mandatory salt iodization programme in Orissa that has been in force since 1989. There is a need to improve the situation through enforcing monitoring of salt iodization to ensure quality and increasing the level of awareness about the iodized salt for sustainable prevention and control of iodine deficiency.

Lymphatic filariasis in Khurda district of Orissa, India: an epidemiological study.

A cross-sectional survey was undertaken to determine the prevalence of disease due to lymphatic filariasis in Khurda district of Orissa, India. The total disease attributable to filariasis was significantly higher in males (14.79%) than females (10.04%). However, elephantiasis is more prevalent in females, and adenolymphangitis is more prevalent in males than their counterparts. The prevalences of various forms of the disease are age dependent in both sexes. About one-seventh of men and women of higher age groups suffered from chronic debilitation forms of the disease. The study suggests that overt clinical forms of lymphatic filariasis constitute a major public health problem in the study area.

Nutritional status of preschool children in the drought affected Kalahandi district of Orissa.

A community-based cross-sectional study was undertaken to determine the magnitude of undernutrition and protein-energy malnutrition among young children during 1996-97 in drought affected Kalahandi district of Orissa. A total of 751 children aged 0-5 yr were studied for anthropometry and clinical signs of nutritional deficiencies from 15 Gram Panchayats selected using probability proportionate to size sampling. There was no significant difference between boys and girls for nutritional status. According to weight-for-age, 57.1 per cent of the children were suffering from underweight (< median -2SD) and 21.3 per cent of children had very low body weights which were < -3SD of standard. Height-for-age and weight-for-height data showed that 41.8 per cent of children suffered from stunting and 27.9 per cent recorded wasting. The children below one year of age had relatively lower prevalence of malnutrition than the other age groups. The prevalence of clinical PEM in the form of marasmus was found in 0.7 per cent of children, while kwashiorkor was absent. This study showed that malnutrition is still a leading problem among preschool children of Kalahandi district and this has not improved in spite of nutrition intervention programmes which are currently in operation.
