Protein-energy malnutrition in northern Sudan: prevalence, socio-economic factors and family background

Increasing prevalence of type 2 diabetes mellitus and impact of ethnicity in north Sudan

BACKGROUND

Diabetes mellitus constitutes a global health threat, with increasing burden of disease in low and middle-income countries witnessing ongoing epidemiological transition including Sudan.

AIMS

To study the prevalence of type 2 diabetes mellitus (T2DM) and prediabetes and determine the relationship to gender, age, waist circumference, body mass index, residence and ethnicity among the adult population in north Sudan.

METHODS

A cross-sectional, population-based study in Northern State and River Nile State using random multi-stage cluster sampling targeting 5376 participants from 14 localities divided into 60 urban and 40 rural clusters. In each cluster, 60 households were studied. Blood glucose level and anthropometric measurements were recorded and a questionnaire containing demographic data was obtained from each participant.

RESULTS

The prevalence of T2DM among participants was 18.7% and prediabetes was 12.9%. Among people living with T2DM, 694(71.0%) were known cases of T2DM, whereas 284(29.0%) were newly diagnosed cases. The significant associated risk factors for T2DM included urban residence (AOR 1.23, 95%CI 1.09-1.41), age above 60 years (AOR 4.77, 95%CI 4.04-5.63), obese BMI (AOR 1.26, 95%CI 1.03-1.55) and central obesity (AOR 1.39, 95%CI 1.14-1.68). Compared to indigenous population, individuals of Egyptian descents (AOR 1.28, 95%CI 1.04-1.57) and mixed origin (AOR 1.24, 95%CI 1.04-1.48) had increased risk of T2DM.

CONCLUSION

The prevalence of T2DM and prediabetes in north Sudan have increased significantly since 1996 with variations between ethnicities which showed to be an independent risk factor for T2DM. Health authorities are recommended to set plans to meet the health needs of these communities.

The association between malaria and malnutrition among under-five children in Shashogo District, Southern Ethiopia: a case-control study

Background

Recent studies have presented conflicting findings about whether malaria is associated with an increased or decreased risk of malnutrition. Therefore, assessing the relationship between these two disastrous diseases in the most vulnerable groups, such as in children aged below 5 years (under-five children), may lead to the discovery of new low-cost and effective aides to current methods of malnutrition prevention in malaria-endemic areas. Therefore, this study was conducted to assess the relationship between malaria and malnutrition among under five children in an area with a high degree of malaria transmission.

Methods

The study involved comparing malnourished children aged 6–59 months and nourished children of the same age for their past exposure to malaria, in Shashogo District, Southern Ethiopia. A validated structured questionnaire was used to collect home to home socioeconomic data and anthropometric instruments for clinical data. The collected data were analysed using descriptive and inferential statistics by means of EpiData entry software and STATA data analysis software.

Results

A total of 356 (89 malnourished and 267 nourished) under-five children participated in the study. Previous exposure to Plasmodium infection was found to be a predictor for the manifestation of malnutrition in under-five children (P = 0.02 [OR = 1.87, CI = 1.115–3.138]). Children from a household with a monthly income of less than USD 15 were 4.5 more likely to be malnourished as compared to the other children (P = 0.001 [OR = 0.422, CI = 0.181–0.978]).

Conclusion

This study found that exposure to Plasmodium has a significant impact on the nutritional status of children. In addition, socio-demographic factors, such as family income, may play a role in determining whether children are malnourished or not and may lead to increased morbidity due to malnourishment in children living in malaria-endemic areas. Therefore, malnutrition control interventions should be consolidated with malaria prevention strategies particularly in high malaria transmission areas.

Social, dietary and clinical correlates of oedema in children with severe acute malnutrition: a cross-sectional study

BACKGROUND

Severe acute malnutrition is a serious public health problem, and a challenge to clinicians. Why some children with malnutrition develop oedema (kwashiorkor) is not well understood. The objective of this study was to investigate socio-demographic, dietary and clinical correlates of oedema, in children hospitalised with severe acute malnutrition.

METHODS

We recruited children with severe acute malnutrition admitted to Mulago Hospital, Uganda. Data was collected using questionnaires, clinical examination and measurement of blood haemoglobin, plasma c-reactive protein and α1-acid glycoprotein. Correlates of oedema were identified using multiple logistic regression analysis.

RESULTS

Of 120 children included, 77 (64%) presented with oedematous malnutrition. Oedematous children were slightly older (17.7 vs. 15.0 months, p = 0.006). After adjustment for age and sex, oedematous children were less likely to be breastfed (odds ratio (OR): 0.19, 95%-confidence interval (CI): 0.06; 0.59), to be HIV-infected (OR: 0.10, CI: 0.03; 0.41), to report cough (OR: 0.33, CI: 0.13; 0.82) and fever (OR: 0.22, CI: 0.09; 0.51), and to have axillary temperature > 37.5 °C (OR: 0.28 CI: 0.11; 0.68). Household dietary diversity score was lower in children with oedema (OR: 0.58, CI: 0.40; 85). No association was found with plasma levels of acute phase proteins, household food insecurity or birth weight.

CONCLUSION

Children with oedematous malnutrition were less likely to be breastfed, less likely to have HIV infection and had fewer symptoms of other infections. Dietary diversity was lower in households of children who presented with oedema. Future research may confirm whether a causal relationship exists between these factors and nutritional oedema.

Risk factors for severe acute malnutrition in children below 5 y of age in India: a case-control study

OBJECTIVE

To determine the possible risk factors for severe acute malnutrition (SAM) in children below 5 y admitted in a hospital in north India.

METHODS

This case-control study was conducted in a medical college hospital in children below 5 y of age. All cases of SAM (diagnosed as per WHO definition) between 6 and 59 mo of age were compared with age-matched controls with weight for height above -2SD of WHO 2006 growth standards. Data regarding socio-demographic parameters, feeding practices and immunization were compared between the groups by univariable and multivariable logistic regression models.

RESULTS

A total of 76 cases and 115 controls were enrolled. Among the 14 factors compared, maternal illiteracy, daily family income less than Rs. 200, large family size, lack of exclusive breast feeding in first 6 mo, bottle feeding, administration of pre-lacteals, deprivation of colostrum and incomplete immunization were significant risk factors for SAM. Regarding complementary feeding, it was the consistency, rather than the age of initiation, frequency and variety which showed a significant influence on occurrence of SAM. Multivariate analysis revealed that the risk of SAM was independently associated with 6 factors, namely, illiteracy among mothers, incomplete immunization, practice of bottle feeding, consistency of complementary feeding, deprivation of colostrum and receipt of pre-lacteals at birth.

CONCLUSIONS

The present study identifies certain risk factors which need to be focused on during health planning and policy making related to children with SAM in India.

Predicators for weight gain in children treated for severe acute malnutrition: a prospective study at nutritional rehabilitation center

Introduction. Despite being an important health problem in developing countries, there is little information available on factors affecting the severe acute malnutrition, especially nondietary factors. Objective. To study the impact of various factors, especially nondietary ones affecting directly or indirectly the weight gain in children with severe acute malnutrition. Method. A total of 300 children in the age group of 6 to 60 months meeting the WHO criteria for severe acute malnutrition were enrolled in the study. These children were provided special therapeutic diet as recommended by WHO/UNICEF protocol. Children were called for followup every 15 days up to 2 months after discharge to evaluate whether these children have achieved a final target weight gain of 15% of their admission weight. The impact of nondietary factors related to child, mother, and socioeconomic status was evaluated. Data collected through structured questionnaire were analyzed. Result. 172 (57.4%) of the total 300 children did not gain final target weight despite giving adequate diet. We observed that impact of various nondietary factors like mother's educational status and her knowledge about feeding practices, socioeconomic status, previous history, and present evidence of infection in child was important in determining the weight of child. No association was found with gender of child, BMI of mother, and father's educational status on the weight gain of child. Conclusion. The findings of this study confirm the association of many nondietary factors with weight gain in children treated for severe acute malnutrition. To reduce malnutrition emphasis should be given on these factors.

Risk factors for under-nutrition among children aged one to five years in Udupi taluk of Karnataka, India: A case control study

BACKGROUND

Despite her apparent economic success, India is plagued by a high burden of under-nutrition among children under five. This study was aimed at understanding some of the risk factors for under-nutrition in a region with favourable maternal and child health indicators.

METHOD

A case control study was carried out among children aged one to five years attending the paediatric outpatient department in six rural health care centres in Udupi taluk of Karnataka in Southern India. A total of 162 children were included in the study, of which 56 were cases. A semi-structured questionnaire was used to interview the caregivers of the children and the nutritional status was graded according to the Indian Academy of Paediatrics (IAP) grading of protein-energy malnutrition.

RESULTS

Under-nutrition was associated with illness in the last one month [OR- 4.78 (CI: 1.83 -12.45)], feeding diluted milk [OR-14.26 (CI: 4.65 - 43.68)] and having more than two children with a birth interval ≤2 years [OR- 4.93 (CI: 1.78 - 13.61)]. Lack of exclusive breast feeding, level of education of the caregiver and environmental factors like source of water did not have an association.

CONCLUSION

Childhood illness, short birth interval and consumption of diluted milk were some of the significant contributory factors noted among this population. Information, Education, Communication (IEC) campaigns alleviating food fads and promoting birth spacing is needed.

What's new? Investigating risk factors for severe childhood malnutrition in a high HIV prevalence South African setting

AIM

To identify risk factors for severe childhood malnutrition in a rural South African district with a high HIV/AIDS prevalence.

DESIGN

Case-control study.

SETTING

Bushbuckridge District, Limpopo Province, South Africa.

PARTICIPANTS

100 children with severe malnutrition (marasmus, kwashiorkor, and marasmic kwashiorkor) were compared with 200 better nourished (>-2 SD weight-for-age) controls, matched by age and village of residence. Bivariate and multivariate analyses were conducted on a variety of biological and social risk factors.

RESULTS

HIV status was known only for a minority of cases (39%), of whom 87% were HIV positive, while 45% of controls were stunted. In multivariate analysis, risk factors for severe malnutrition included suspicion of HIV in the family (parents or children) (OR 217.7, 95% CI 22.7-2091.3), poor weaning practices (OR 3.0, 95% CI 2.0-4.6), parental death (OR 38.0, 95% CI 3.8-385.3), male sex (OR 2.7, 95% CI 1.2-6.0), and higher birth order (third child or higher) (OR 2.3, 95% CI 1.0-5.1). Protective factors included a diverse food intake (OR 0.53, 95% CI 0.41-0.67) and receipt of a state child support grant (OR 0.44, 95% CI 0.20-0.97). A borderline association existed for family wealth (OR 0.9 per unit, 95% CI 0.83-1.0), father smoking marijuana (OR 3.9, 95% CI 1.1-14.5), and history of a pulmonary tuberculosis contact (OR 3.2, 95% CI 0.9-11.0).

CONCLUSIONS

Despite the increasing contribution of HIV to the development of severe malnutrition, traditional risk factors such as poor nutrition, parental disadvantage and illness, poverty, and social inequity remain important contributors to the prevalence of severe malnutrition. Interventions aiming to prevent and reduce severe childhood malnutrition in high HIV prevalence settings need to encompass the various dimensions of the disease: nutritional, economic, and social, and address the prevention and treatment of HIV/AIDS.

Clinical epidemiology of paediatric disease at Nchelenge, north-east Zambia

In a combined retrospective and prospective 4-year study of 6412 children consecutively admitted to St Paul's Hospital, Nchelenge, north-east Zambia, the clinical epidemiology of paediatric disease was described. One diagnosis per admission was noted. Protein-energy malnutrition (PEM) was diagnosed clinically and by means of a modified Wellcome scheme using weight-for-height and Z scores. Correlation coefficients were calculated between monthly admission rates and relative humidity, rainfall and temperature. The age distribution of admitted children showed several distinct groups. Type I (malaria, acute gastro-enteritis, pneumonia and meningitis) had its peak in the 1st 7 months of age, type II (burn wounds and measles) had its main prevalence between the ages of 2 and 4 years, and type III (trauma, typhoid fever, snake bite and tropical ulcer) occurred mainly between 4 and 14 years of age. Admission rates for PEM, PEM subtypes, pneumonia, trauma and snake bite correlated with wet season variables. Malaria and acute gastro-enteritis were extremely common throughout the year. A measles epidemic in the dry season was initially followed by an increase in marasmus, whereas oedematous malnutrition only assumed epidemic proportions associated with a post-measles rise in admission rates of pneumonia. Clinical epidemiological data at the district level is a powerful tool for understanding the pattern of serious paediatric disease in the community.
