Principal component analysis of socioeconomic factors and their association with malaria in children from the Ashanti Region, Ghana.

ABSTRACT:

Background

The socioeconomic and sociodemographic situation are important components for the design and assessment of malaria control measures. In malaria endemic areas, however, valid classification of socioeconomic factors is difficult due to the lack of standardized tax and income data. The objective of this study was to quantify household socioeconomic levels using principal component analyses (PCA) to a set of indicator variables and to use a classification scheme for the multivariate analysis of children<15 years of age presented with and without malaria to an outpatient department of a rural hospital.

Methods

In total, 1,496 children presenting to the hospital were examined for malaria parasites and interviewed with a standardized questionnaire. The information of eleven indicators of the family's housing situation was reduced by PCA to a socioeconomic score, which was then classified into three socioeconomic status (poor, average and rich). Their influence on the malaria occurrence was analysed together with malaria risk co-factors, such as sex, parent's educational and ethnic background, number of children living in a household, applied malaria protection measures, place of residence and age of the child and the mother.

Results

The multivariate regression analysis demonstrated that the proportion of children with malaria decreased with increasing socioeconomic status as classified by PCA (p<0.05). Other independent factors for malaria risk were the use of malaria protection measures (p<0.05), the place of residence (p<0.05), and the age of the child (p<0.05).

Conclusions

The socioeconomic situation is significantly associated with malaria even in holoendemic rural areas where economic differences are not much pronounced. Valid classification of the socioeconomic level is crucial to be considered as confounder in intervention trials and in the planning of malaria control measures.

Project description:BackgroundChildhood immunization is one of the most cost effective health interventions but its rate has been declining recently in Ghana. Information on immunization coverage and determinants is needed to improve immunization programmes. The objective of this study was to determine the prevalence and factors associated with incomplete immunization of children (12-23 months) in Kwabre East District, Ghana.MethodsA cross-sectional, community-based survey involving 322 children and their mothers was carried out. Data were collected on socio-demographic characteristics of mothers, childhood immunization history and mothers' knowledge and practices of immunization using a structured questionnaire. Children were classified as incompletely immunized if they failed to receive at least one of 8 vaccine doses: - one dose of Bacillus Calmette-Guérin (BCG), 3 doses each of pentavalent, 3 doses of polio and one dose of measles per WHO/UNICEF definition. Chi-square and logistic regression analyses were used to identify the factors associated with incomplete immunisation.ResultsThe prevalence of incomplete immunization was low (15.5%) suggesting high immunisation coverage but the coverage of the second measles dose, taken at 18 months of age, was the lowest (23.9%). Most of the mothers knew the importance of immunisation (95.7%) and at least one vaccine-preventable disease or symptom (84.9%). Two factors associated with incomplete immunisation in bivariate analyses (community of residence, and mother's knowledge of number of oral polio vaccines given to children) were no longer significant in a logistic regression model. Compared to children in Aboaso, children in Gyamfi Wonoo (AOR = 1.81, 95% CI = 0.80-4.08), Mamponteng (Bonwunu) (AOR = 0.59, 95% CI = 0.24-1.48) and Mamponteng (Town) (AOR = 0.63, 95% CI = 0.26-1.55) had similar odds of incomplete immunisation. Similarly, mother's lack of knowledge of the number of doses of polio vaccine given to children had no effect on the odds of incomplete immunisation (AOR = 0.53, 95% CI = 0.22-1.26).ConclusionsImmunization coverage is high in the Kwabre East district but very few children received the second measles dose. None of the maternal and child factors assessed is associated with immunisation coverage. Further research is needed to identify the determinants of immunisation coverage and the reasons for the low uptake of second measles dose in the study area.

Project description:Background:Iodine deficiency is a public health problem. The universal salt iodization (USI) program is the main, simple, and cost-effective intervention strategy to control iodine deficiency. The study examined the iodine status in school-aged children in Ashanti region, Ghana, using thyroid volumes along with urinary iodine concentrations, the methods recommended by the WHO/ICCIDD for monitoring the sustained impact of USI programs. Methods:This cross-sectional study was conducted among school-aged children (6-12 years) from randomly selected schools in the central and northern part of the Ashanti region, Kumasi Metropolis, and Ejura-Sekyedumase Municipality, respectively. A total of 852 children were enrolled in the study. Thyroid volume and urinary iodine concentrations of the children were determined using the standardized methods recommended by WHO/ICCIDD. Anthropometric measurements were also evaluated. Results:The mean values of thyroid volume in female and male school-aged children were 3.53?±?0.09 and 3.32?±?0.07, respectively. The thyroid size was significantly associated with age (P < 0.0001), weight (P < 0.0001), height (P < 0.0001), BMI (P < 0.05), and BSA (P < 0.0001) by Pearson's correlation in both males and females. The P50 (median) thyroid volumes of school children investigated in this study were generally larger compared to the WHO/ICCIDD reference data by age and body surface area. The median value of urinary iodine concentration was 201.85??g/L, which showed significant sex difference (P value <0.0001). Excessive iodine nutrition (?300??g/L) was observed among 34.4% of male children and 27.6% of female children. Also, 12.8% of the male and 19.5% of the female children had UIC below requirement (<100??g/L). The criteria of thyroid volume per age yielded a goitre prevalence of 2.2%. In contrast, the criteria of thyroid volume by body surface area yielded a goitre prevalence of 0.9%. Conclusion:The study clearly indicated that adequate iodine nutrition exists generally among the school children. However, insufficient and excessive iodine intakes still persist among some of the children. The establishment of local reference values for thyroid volume that might be applicable to precisely define goitre prevalence in the Ghanaian context is highly recommended.

Project description:BackgroundStudies have reported a poor diet quality among children in Ghana and other developing countries. Inadequate dietary diversity among children may lead to deficiencies in micronutrient intake necessary for growth and other cognitive functions. Understanding factors associated with infants' diverse diets is a key step to promoting adequate infant and young child nutrition. This study sought to determine the factors associated with food consumption and dietary diversity (DD) among infants.MethodsIn this cross-sectional study among 1503 mothers-infant (aged 6-18 months) pairs from rural, urban, and peri-urban districts of Ashanti Region, factors associated with food consumption and DD were evaluated. The FAO 18-food group DD questionnaire was used to determine previous food group intake, while a structured questionnaire was used to capture data on the mother's socio-demographic parameters and child morbidity. Data were analyzed using descriptive statistics, the Chi-square test, and binary logistic regression to compare mothers and infants who had adequate and inadequate DDS of 9 out of 18 food groups and the predictors of dietary diversity.ResultsAbout 64.7% of the infants did not meet the minimum dietary diversity. Over two-third (77.4%) of the children consumed maize porridge the previous day. Foods which were less consumed included vegetables (35%), animal milk (38.9%), and meat (organ 14%, any meat 26%). The mean food group intake from 18 food groups was 7.0, and the majority (64.7%) did not meet the recommended 9 food group intake. Significantly more younger children (6-11 months) (74%, p<0.001) compared with older children (12-18 months) (52.5%) did not meet the minimum DDS. Also compared with the older children, the younger ones had above two times increased odds of inadequate DD (OR = 2.5, p<0.001, 95% CI = 1.4-4.4). When controlled for gender, children from peri-urban areas (OR = 5.2, p = 0.260, 95% CI = 0.2-93.2) and rural areas (OR = 1.8, p = 0.650, 95% CI = 0.2-9.3) had increased odds of lower DD than urban children. Children of unemployed caregivers had an increased odds of low DD (OR = 2.3 p<0.001, 95% CI 1.7-3.2) compared with children of employed caregivers. Finally, children of caregivers with better nutrition knowledge (nine correct answers from 12 questions) had lower odds of having lower dietary diversity (adjusted OR = 0.9, p = 0.85, 95%CI = 0.5-1.6) than those with less knowledge.ConclusionsLow DD was common among infants and associated with infants age, caregivers' areas of residence, employment status, and level of nutrition education. Children who did not meet the minimum dietary diversity were not fed particular foods such as vegetables, animal milk, and organ meat. Proper maternal nutrition education and feeding practices targeting age-specific needs and community livelihood support systems are necessary to improve dietary diversity of infants.

Project description:BackgroundIron Deficiency Anaemia (IDA) is reportedly high in pregnant adults and the causes well studied. However, among pregnant teenagers, the levels and associated factors of IDA are not fully understood.MethodsIn a prospective cohort study among Ghanaian pregnant teenagers, aged 13-19 years, IDA prevalence and associated factors were investigated. Sociodemographic data, household hunger scale (HHS), lived poverty index (LPI), FAO's women's dietary diversity score (WDDS) and interventions received during antenatal care (ANC) were obtained from 416 pregnant teenagers in Ashanti Region, Ghana. Micronutrient intakes using a repeated 24-hour dietary recall, and mid-upper arm circumference (MUAC) were determined and blood samples analysed for haemoglobin (Hb), serum levels of ferritin, prealbumin, vitamin A, total antioxidant capacity (TAC), C-reactive protein (CRP), and zinc protoporphyrin (ZPP).ResultsAnaemia (Hb cutoff <11.0 g/dL) was 57.1%; deficient systemic supply of iron stores (31.4%), depleted body stores of iron (4.4%), inadequate dietary iron intake (94.5%), and inadequate multiple micronutrient intakes (49.5%), were all notable among study participants. Between-subject effects using Generalized Linear Modelling indicated malaria tablet given at ANC (p = 0.035), MUAC (p = 0.043), ZPP (p<0.001), ZPP/Hb ratio (p<0.001) and depleted body iron stores (DBIS) (p<0.001) to significantly affect Hb levels. Pregnant teenagers with a high ZPP/Hb ratio (OR = 9.7, p<0.001, 95%CI = 6.0-15.8) had increased odds of being anaemic compared to those with normal ZPP/Hb ratio. Participants who were wasted (OR = 1.2, p = 0.543, 95%CI = 0.6-2.3), and those with depleted iron stores (OR = 3.0, p = 0.167, 95%CI = 0.6-14.6) had increased odds of being anaemic. Participants who experienced hunger were close to 3 times more likely (OR = 2.9, p = 0.040, 95%CI = 1.1-7.8) for depleted iron stores, compared to those who did not experience hunger. Also, participants with inadequate multiple micronutrients intakes (OR = 2.6, p = 0.102, 95%CI = 0.8-8.4), and those with low serum levels of ferritin (OR = 3.3, p = 0.291, 95%CI = 0.4-29.2) had increased odds of depleted body iron stores.ConclusionsIDA is common among pregnant teenagers and the related factors include malaria tablets given at ANC, maternal hunger, maternal MUAC, a deficient systemic supply of iron, depleted body iron stores, ZPP, and ZPP/Hb ratio. Appropriate interventions are urgently needed to address the causes of IDA among pregnant teenagers.
