Caretakers' perception towards using zinc to treat childhood diarrhoea in rural western Kenya

Childhood diarrhoea: a cross-sectional survey on maternal knowledge, hygienic practices and use of oral zinc for home management in a Nigerian community

Introduction

diarrhoea is the second leading cause of morbidity and mortality in young children. The aim was to assess maternal knowledge, hygienic practices and home management (HM) of diarrhoea with oral rehyrdation therapy (ORT) and oral zinc in children aged 6-23 months in western Nigeria. Predictors of good knowledge and practice were also assessed.

Methods

this was a community based analytic cross-sectional study. Multistage sampling was used to select mothers of children 6-23 months of age. Data were collected using pre-tested, interviewer administered questionnaires and analyzed using SPSS version 20. Bivariate analysis and multiple logistic regression for predictor variables were done. Level of significance was set at 0.05.

Results

three hundred and seventy one (371) respondents were interviewed (mean age 30.4 ± 5.02 years). 305 (82.2%) had good knowledge of diarrhoeal diseases, 208(56.1%) had good knowledge of home management of childhood diarrhoea, 274 (73.9%) had good maternal hygienic practices and 161 (61.2%) of the 263 mothers who had managed diarrhoea in their children, had good practice. Only 34 (12.9%) of them used zinc tablets and 11 (32.4%) did not complete the full course. Maternal age 30-39 years predicted good knowledge (AOR 3.19 CI 2-6.05). Predictors of good home management practices were: maternal age 30-39 years (AOR 2.78 CI 1.44-5.37), >40 years (AOR 5.55 CI 1.54-20.01) and younger age of the index child, 6-11 months (AOR 4.83 CI 2.29-10.18).

Conclusion

mothers had poor knowledge of the role of zinc supplementation in childhood diarrhoea and use of zinc tablets for diarrhoea was very low. Community based health education should be carried out.

Tuberculosis case finding using population-based disease surveillance platforms in urban and rural Kenya

Background

Tuberculosis (TB) case finding is an important component of TB control because it can reduce transmission of Mycobacterium tuberculosis (MTB) through prompt detection and treatment of infectious patients.

Methods

Using population-based infectious disease surveillance (PBIDS) platforms with links to health facilities in Kenya we implemented intensified TB case finding in the community and at the health facilities, as an adjunct to routine passive case finding conducted by the national TB program. From 2011 to 2014, PBIDS participants ≥15 years were screened either at home or health facilities for possible TB symptoms which included cough, fever, night sweats or weight loss in the preceding 2 weeks. At home, participants with possible TB symptoms had expectorated sputum collected. At the clinic, HIV-infected participants with possible TB symptoms were invited to produce sputum. Those without HIV but with symptoms lasting 7 days including the visit day had chest radiographs performed, and had sputum collected if the radiographs were abnormal. Sputum samples were tested for the presence of MTB using the Xpert MTB/RIF assay. TB detection rates were calculated per 100,000 persons screened.

Results

Of 11,191 participants aged ≥15 years screened at home at both sites, 2695 (23.9%) reported possible TB symptoms, of whom 2258 (83.8%) produced sputum specimens. MTB was detected in 32 (1.4%) of the specimens resulting in a detection rate of 286/100,000 persons screened. At the health facilities, a total of 11,762 person were screened, 7500 (63.8%) had possible TB symptoms of whom 1282 (17.1%) produced sputum samples. MTB was detected in 69 (5.4%) of the samples, resulting in an overall detection rate of 587/100,000 persons screened. The TB detection rate was higher in persons with HIV compared to those without at both home (HIV-infected - 769/100,000, HIV-uninfected 141/100,000, rate ratio (RR) – 5.45, 95% CI 3.25–22.37), and health facilities (HIV-infected 3399/100,000, HIV-uninfected 294/100,000, RR 11.56, 95% CI 6.18–18.44).

Conclusion

Facility-based intensified TB case finding detected more TB cases per the number of specimens tested and the number of persons screened, including those with HIV, than home-based TB screening and should be further evaluated to determine its potential programmatic impact.

Modelling protection behaviour towards micronutrient deficiencies: Case of iodine biofortified vegetable legumes as health intervention for school-going children

BACKGROUND/OBJECTIVES

Despite successes recorded in combating iodine deficiency, more than 2 billion people are still at risk of iodine deficiency disorders. Rural landlocked and mountainous areas of developing countries are the hardest hit, hence the need to explore and advance novel strategies such as biofortification.

SUBJECTS/METHODS

We evaluated adoption, purchase, and consumption of iodine biofortified vegetable legumes (IBVL) using the theory of protection motivations (PMT) integrated with an economic valuation technique. A total of 1,200 participants from three land-locked locations in East Africa were recruited via multi-stage cluster sampling, and data were collected using two, slightly distinct, questionnaires incorporating PMT constructs. The survey also elicited preferences for iodine biofortified foods when offered at a premium or discount. Determinants of protection motivations and preferences for iodine biofortified foods were assessed using path analysis modelling and two-limit Tobit regression, respectively.

RESULTS

Knowledge of iodine, iodine-health link, salt iodization, and biofortification was very low, albeit lower at the household level. Iodine and biofortification were not recognized as nutrient and novel approaches, respectively. On the other hand, severity, fear, occupation, knowledge, iodine status, household composition, and self-efficacy predicted the intention to consume biofortified foods at the household level; only vulnerability, self-efficacy, and location were the most crucial elements at the school level. In addition, results demonstrated a positive willingness-to-pay a premium or acceptance of a lesser discount for biofortification. Furthermore, preference towards iodine biofortified foods was a function of protection motivations, severity, vulnerability, fear, response efficacy, response cost, knowledge, iodine status, gender, age. and household head.

CONCLUSIONS

Results lend support for prevention of iodine deficiency in unprotected populations through biofortification; however 'threat' appraisal and socio-economic predictors are decisive in designing nutrition interventions and stimulating uptake of biofortification. In principle, the contribution is threefold: 1) Successful application of the integrated model to guide policy formulation; 2) Offer guidance to stakeholders to identify and tap niche markets; 3) stimulation of rural economic growth around school feeding programmes.
