A multilevel analysis of lifestyle variations in symptoms of acute respiratory infection among young children under five in Nigeria

Household heating fuels impact on Acute Respiratory Infection (ARI) symptoms among children in Punjab, Pakistan

Exposure to household air pollution (HAP) accounted for the loss of 86 million healthy lives in 2019, with almost half of all deaths due to lower respiratory infection among children under 5 years of age. Similarly, the situation in Punjab - Pakistan's largest province - is also not promising. This study was conducted to examine household energy consumption and respiratory symptoms among children under the age of five in rural and urban areas of Punjab. Using data from the Multiple Indicator Cluster Survey (MICS) 2017-18, logistic regression models were applied to the data of a sample of 35,000 children under the age of five living in households with polluting heating fuels. A hypothesis was formulated to investigate the relationship between polluting heating activities and respiratory infections among children under five. Those Children who live in households having traditional space heaters without chimneys are 50% more likely to have symptoms of Acute Respiratory Infection (ARI) compared to those whose households have chimneys with traditional space heaters. When households utilize polluting heating fuel, the likelihood of children experiencing rapid, shortness of breath increases by 49%, and the likelihood of children displaying ARI symptoms characterized by coughing rises by approximately 30%. This study proposed a complete banning of polluting heating activities and replacing it with cleaner ones using financial incentives. It is pertinent to raise awareness campaigns majorly focusing on the guidelines to adopt better heat output with less harmful emissions.

Prevalence, potential determinants, and treatment-seeking behavior of acute respiratory infection among children under age five in India: Findings from the National Family Health Survey, 2019-21

BACKGROUND

Acute respiratory infections (ARI) are a major cause of mortality and morbidity among under-five children worldwide, particularly in developing countries. Current evidence using nationally representative data on determinants and care-seeking behavior for ARI is limited in the Indian context. Hence, the present study complements the existing literature by examining the prevalence, determinants, and health-care-seeking behavior regarding ARI among Indian children under age five.

STUDY DESIGN

Cross-sectional study.

METHODS

The data for the present study were drawn from the fifth round of the National Family Health Survey (NFHS-5) conducted in 28 states and 8 union territories of India in 2019-21. A total of 222,233 children age less than five years were selected to estimate the prevalence and determinants of ARI, and 6198 children having ARI were selected to explore the treatment-seeking behavior. Bivariate analysis and multivariable binary logistic regression analysis were employed.

RESULTS

Among children under five years, 2.8% suffered from ARI in the two weeks preceding the survey, and 56.1% sought treatment for ARI. Younger age, a recent episode of diarrhea, maternal asthmatic history, and tobacco smoke exposure in the household increase the risk of having ARI. Further, having a separate room as a kitchen in the household reduces the likelihood of having ARI by 14% (AOR: 0.86; CI: 0.79-0.93). Female children (AOR: 0.88; CI: 0.77-1.00) and children belonging to households having difficulty in accessing transport to health facility (AOR: 0.83; CI: 0.69-0.99) are less likely to seek treatment.

CONCLUSION

The study identified several socio-demographic, maternal, and household characteristics associated with ARI and treatment seeking for ARI. The study also recommends making health centers more accessible to the people in terms of proximity and cost.

Systematic review of multilevel models involving contextual characteristics in African demographic research

Multilevel modelling has become a popular analytical approach for many demographic and health outcomes. The objective of this paper is to systematically review studies which used multilevel modelling in demographic research in Africa in terms of the outcomes analysed, common findings, theoretical rationale, questions addressed, methodological approaches, study design and data sources. The review was conducted by searching electronic databases such as Ebsco hosts, Science Direct, ProQuest, Scopus, PubMed and Google scholar for articles published between 2010 and 2021. Search terms such as neighbourhood, social, ecological and environmental context were used. The systematic review consisted of 35 articles, with 34 being peer-reviewed journal articles and 1 technical report. Based on the systematic review community-level factors are important in explaining various demographic outcomes. The community-level factors such as distance to the health facility, geographical region, place of residence, high illiteracy rates and the availability of maternal antenatal care services influenced several child health outcomes. The interpretation of results in the reviewed studies mainly focused on fixed effects rather than random effects. It is observed that data on cultural practices, values and beliefs, are needed to enrich the robust evidence generated from multilevel models.

Acute lower respiratory infections among children under five in Sub-Saharan Africa: a scoping review of prevalence and risk factors

BACKGROUND

Acute lower respiratory tract infections (ALRTIs) among children under five are still the leading cause of mortality among this group of children in low and middle-income countries (LMICs), especially countries in sub-Saharan Africa (SSA). This scoping review aims to map evidence on prevalence and risk factors associated with ALRTIs among children under 5 years to inform interventions, policies and future studies.

METHODS

A thorough search was conducted via four main databases (PubMed, JSTOR, Web of Science and Central). In all, 3,329 records were identified, and 107 full-text studies were considered for evaluation after vigorous screening and removing duplicates, of which 43 were included in this scoping review.

FINDINGS

Findings indicate a high prevalence (between 1.9% to 60.2%) of ALRTIs among children under five in SSA. Poor education, poverty, malnutrition, exposure to second-hand smoke, poor ventilation, HIV, traditional cooking stoves, unclean fuel usage, poor sanitation facilities and unclean drinking water make children under five more vulnerable to ALRTIs in SSA. Also, health promotion strategies like health education have doubled the health-seeking behaviours of mothers of children under 5 years against ALRTIs.

CONCLUSION

ALRTIs among children under five still present a significant disease burden in SSA. Therefore, there is a need for intersectoral collaboration to reduce the burden of ALRTIs among children under five by strengthening poverty alleviation strategies, improving living conditions, optimising child nutrition, and ensuring that all children have access to clean water. There is also the need for high-quality studies where confounding variables in ALRTIs are controlled.

Associations Between Indoor Air Pollutants and Risk Factors for Acute Respiratory Infection Symptoms in Children Under 5: An Analysis of Data From the Indonesia Demographic Health Survey

OBJECTIVES

The study investigated the association between indoor air pollution (IAP) and risk factors for acute respiratory infection (ARI) symptoms in children under 5 years of age.

METHODS

A cross-sectional study was conducted using data derived from Indonesia Demographic and Health Survey in 2017. Binary logistic regression modeling was employed to examine each predictor variable associated with ARI among children under 5 years of age in Indonesia.

RESULTS

The study included a total of 4936 households with children. Among children under 5 years old, 7.2% reported ARI symptoms. The presence of ARI symptoms was significantly associated with the type of residence, wealth index, and father's smoking frequency, which were considered the sample's socio-demographic characteristics. In the final model, living in rural areas, having a high wealth index, the father's smoking frequency, and a low education level were all linked to ARI symptoms.

CONCLUSIONS

The results revealed that households in rural areas had a substantially higher level of reported ARI symptoms among children under 5 years old. Furthermore, the father's smoking frequency and low education level were associated with ARI symptoms.

Multilevel Analysis of Lifestyle and Household Environment for Toddlers With Symptoms of Acute Respiratory Infection (ARI) in Indonesia in 2007, 2012, and 2017

Introduction. The morbidity and mortality rate of Acute Respiratory Tract Infection (ARI) in children under 5 is relatively high in Indonesia. Socio-demographic characteristic is considered one of the factors causing ARI in Indonesia. However, no study analyzed the prevalence of ARI among toddlers and the differences among the determinant factors in multiple periods. Thus, this study aimed to analyze the prevalence trends and determinant factors associated with ARI symptoms in children under 5 in Indonesia in 2007, 2012, and 2017. Methods. This study analyzed cross-sectional survey data from the Demographic and Health Survey (DHS) in Indonesia during 2007, 2012, and 2017. Bivariate and multivariate analysis with logistic regression was performed using Stata version 15. The final results were expressed in Adjusted Odds Ratio (AORs) and 95% Confidence Interval (CI). Results. The findings showed a progress in prevalence trends with a decrease in the percentage of children with ARI symptoms from 11.25% (2007), then 5.12% (2012) to 4.22% (2017). Risk factors for toddlers experiencing ARI symptoms were as follows: younger maternal age (OR: 1.13, 95% Cl 0.70-1.81 in 2007, OR: 1.72, 95% Cl 1.03-2.88 in 2012 and OR: 0.98, 95% Cl 0.48-1.97 in 2017), smoking habits of family members (OR: 1.12, 95% Cl 0.85-1.48 in 2012, OR: 1.23, 95% Cl in 2017), poor drinking water quality (OR: 1.12, 95% Cl 0.85-1.48 in 2012 and OR: 1.23, 95% Cl in 2017), unavailable toilet facilities (OR: 1.27, 95% Cl 1.04-1.56 in 2007, OR: 1.24, 95% Cl 0.95-1.63 in 2012 and OR: 1.28, 95% Cl 0.97-1.68 in 2017). Conclusion. There was a decrease in the prevalence of ARI symptoms among children in 2007, 2012, and 2017, with no prominent differences in other related factors. The lifestyle and household environmental factors such as the use of dirty fuel, the presence of smokers in the household, the poor quality of drinking water, unavailable toilet facilities in addition to the maternal age and child age were the determinant factors that must be prioritized and improved. Family self-awareness should also be enhanced for better prospects for toddler survival.

Housing quality and its impact on Acute Respiratory Infection (ARI) symptoms among children in Punjab, Pakistan

Exposure to poor housing quality and household air pollution (HAP) are significant factors for morbidity and mortality in Pakistan. Children under five are particularly at risk of acute respiratory infections (ARIs). Globally, it has been estimated that 6.6 million children less than five years of age die every year from this disease. Little is known regarding the effect of HAP and poor housing quality on children's respiratory symptoms in Pakistan. Statistics concerning Pakistan's largest province, Punjab, are also not promising. Hence, an association between housing quality and respiratory symptoms among children under the age of five in Punjab has been studied in this paper. Using data from MICS 2017-18, logistic regression models were applied to the sample of 35000 children under the age of five living in poor housing quality. We estimated that acute respiratory infection (ARI) symptoms are higher among children when the floor of a house is made of natural material. However, the lower ARI symptoms were found among children living in a house with a wall made of natural material. On the other hand, we found that children residing in the western region of Punjab are at a higher risk of ARI symptoms. The findings remain consistent with the previous researchers. In addition to promoting increased access to quality housing material during construction activities, we suggest that critical community-based interventions are required to combat local issues and problems at the micro-level.

A multilevel analysis of the social determinants associated with symptoms of acute respiratory infection among preschool age children in Pakistan: A population-based survey

BACKGROUND

As advocated by WHO in "Closing the Health Gap in a Generation", dramatic differences in child health are closely linked to degrees of social disadvantage, both within and between communities. Nevertheless, research has not examined whether child health inequalities include, but are not confined to, worse acute respiratory infection (ARI) symptoms among the socioeconomic disadvantaged in Pakistan. In addition to such disadvantages as the child's gender, maternal education, and household poverty, the present study also examined the linkages between the community environment and ARI symptoms among Pakistan children under five. Furthermore, we have assessed gender contingencies related to the aforementioned associations.

METHODS

Using data from the nationally representative 2017-2018 Pakistan Demographic and Health Survey, a total of 11,908 surviving preschool age children (0-59 months old) living in 561 communities were analyzed. We employed two-level multilevel logistic regressions to model the relationship between ARI symptoms and individual-level and community-level social factors.

RESULTS

The social factors at individual and community levels were found to be significantly associated with an increased risk of the child suffering from ARI symptoms. A particularly higher risk was observed among girls who resided in urban areas (AOR = 1.42; p<0.01) and who had a birth order of three or greater.

DISCUSSIONS

Our results underscore the need for socioeconomic interventions in Pakistan that are targeted at densely populated households and communities within urban areas, with a particular emphasis on out-migration, in order to improve unequal economic underdevelopment. This could be done by targeting improvements in socio-economic structures, including maternal education.

Determinants of acute respiratory infection among under-five children in rural Ethiopia

INTRODUCTION

In low- and middle-income nations, acute respiratory infection (ARI) is the primary cause of morbidity and mortality. According to some studies, Ethiopia has a higher prevalence of childhood acute respiratory infection, ranging from 16 to 33.5%. The goal of this study was to determine the risk factors for acute respiratory infection in children under the age of five in rural Ethiopia.

METHODS

A cross-sectional study involving 7911 children under the age of five from rural Ethiopia was carried out from January 18 to June 27, 2016. A two stage cluster sampling technique was used recruit study subjects and SPSS version 20 was used to extract and analyze data. A binary logistic regression model was used to identify factors associated with a childhood acute respiratory infection. The multivariable logistic regression analysis includes variables with a p-value less than 0.2 during the bivariate logistic regression analysis. Adjusted odds ratios were used as measures of effect with a 95% confidence interval (CI) and variables with a p-value less than 0.05 were considered as significantly associated with an acute respiratory infection.

RESULTS

The total ARI prevalence rate among 7911 under-five children from rural Ethiopia was 7.8%, according to the findings of the study. The highest prevalence of ARI was found in Oromia (12.8%), followed by Tigray (12.7%), with the lowest frequency found in Benishangul Gumuz (2.4%). A multivariable logistic regression model revealed that child from Poor household (AOR = 2.170, 95% CI: 1.631-2.887), mother's no education (AOR = 2.050,95% CI: 1.017-4.133), mother's Primary education (AOR = 2.387, 95% CI:1.176-4.845), child had not received vitamin A (AOR = 1.926, 95% CI:1.578-2.351), child had no diarrhea (AOR = 0.257, 95% CI: 0.210-0.314), mothers not working (AOR = 0.773, 95% CI:0.630-0.948), not stunted (AOR = 0.663, 95% CI: 0.552-0.796), and not improved water source (AOR = 1.715, 95% CI: 1.395-2.109). Similarly, among under-five children, the age of the child, the month of data collection, anemia status, and the province were all substantially linked to ARI.

CONCLUSIONS

Childhood ARI morbidity is a serious health challenge in rural Ethiopia, according to this study, with demographic, socioeconomic, nutritional, health, and environmental factors all having a role. As a result, regional governments, healthcare staff, and concerned groups should place a priority on reducing ARI, and attempts to solve the issue should take these variables into account.

How has the COVID-19 pandemic affected gastrointestinal surgery for malignancies and surgical infections?

The coronavirus disease 2019 (COVID-19) pandemic has affected infection control and prevention measures. We investigated the impact of the COVID-19 pandemic on postoperative infections and infection control measures in patients underwent gastrointestinal surgery for malignancies. We retrospectively evaluated changes in clinicopathological features, frequency of alcohol-based hand sanitizer use, frequency of postoperative complications, and microbial findings among our patients in February-May in 2019 (Control group) and 2020 (Pandemic group), respectively. Surgical resection in pathological stage III or IV patients was more frequently performed in the Pandemic group than in the Control group (P = 0.02). The total length of hospitalization and preoperative hospitalization was significantly shorter in the Pandemic group (P = 0.01 and P = 0.008, respectively). During the pandemic, hand sanitizer was used by a patients for an average of 14.9±3.0 times/day during the pandemic as opposed to 9.6±3.0 times/day in 2019 (p<0.0001). Superficial surgical site infection and infectious colitis occurred less frequently during the pandemic (P = 0.04 and P = 0.0002, respectively). In Pandemic group, Enterobacter, Haemophilus, and Candida were significantly decreased in microbiological cultures (P < 0.05, P < 0.05, P = 0.02, respectively) compared with Control group. Furthermore, a significant decrease in Streptococcus from drainage cultures was observed in the Pandemic group (P < 0.05). During the COVID-19 pandemic, a decrease in nosocomial infections was observed in the presence of an increase in alcohol-based hand sanitizer use.

Determinants of Acute Respiratory Infection Among Children Under-Five Years in Indonesia

BACKGROUND

Acute respiratory infection (ARI) among children under five years has been identified as a risk factor for child morbidity, leading to child mortality in Indonesia. Many factors may cause ARI; however, determinants associated with ARI remain unclear in Indonesia.

OBJECTIVES

This study sought to analyze the determinants of ARI among children aged under five years in Indonesia.

METHODS

This study was cross-sectional and utilized secondary data from the 2017 Indonesian Demographic and Health Survey (IDHS). A total of 15,993 children under five years old were selected as respondents. Chi-squared test and binary logistic regression were used to examine the determinants of ARI among children under five years in Indonesia.

RESULTS

Children aged 1 year [Odds Ratio (OR) = 1.43, 95% CI = 1.04-1.97], children aged 2 years [OR = 1.54, 95% CI = 1.12-2.11], mother's occupation [OR = 1.24, 95% CI = 1.01-2.154], poorest wealth index [OR = 1.91, 95% CI = 1.26-2.89], poor [OR = 1.50, 95% CI = 1.01-2.21], region of residence: Western Indonesia [OR = 1.96, 95% CI = 1.28-2.00], Middle of Indonesia [OR = 2.19, 95% CI = 1.44-3.33] were significantly associated with ARI among children under five years in Indonesia.

CONCLUSIONS

This study revealed that the determinants of ARI among children under five years in Indonesia remain related to the socio-demographic aspect. This research highlighted that the family's and the living area's wealth index remains essential in improving children's health outcomes.

PRACTICE IMPLICATIONS

Our findings support increasing awareness of the low-income family through adequate information and health promotion. Advancing the feasibility, accessibility, and affordability of health information and health services across all Indonesian regions should be strengthened.

Family Health Behavior: Preventive Measures against Acute Respiratory Infections in Under-5 Children

BACKGROUND

The under-5 mortality rate in Indonesia is 32 per 1,000 live births, still higher than the SDG target. Acute respiratory infections (ARIs), as one of the leading causes of death, must be prevented. Arguments emerge concerning the association of home crowding, health behavior, and the incidence of ARI.

METHODS

A cross-section analysis with the Indonesia Demographic and Health Survey (IDHS) 2017 dataset is performed. Samples are restricted to 16,555 children aged 0-59 months who lived with their mother (eligible women interviewed) during the survey. For each of the variables observed during this study, missing data must be omitted as exclusion criteria. A 100 per cent answer rate was achieved. Logistic regression was used to determine ARI-associated factors, by examining the effect of each explanatory factor (independent variables) on the odds ratio of ARI (one dependent binary variable).

RESULTS

The prevalence of ARI was more common among children living in the poorest households (AOR 1.66; 95% CI, 1.20 - 2.28) and those exposed to indoor tobacco smoke pollution (AOR 1.27; 95% CI, 1.04-1.56). On the other hand, those aged 0-5 months (AOR 0.59; 95% CI, 0.43-0.82), living at home with improved sanitation (AOR 0.74; 95% CI, 0.61-0.89), and exclusively breastfed (AOR 0.85; 95% CI, 0.73-0.99) were less likely to have ARI.

CONCLUSIONS

Home crowding is not associated with ARI. Efforts should be focused on preserving family health behavior. The family functioned as a health-support system for their under-5 children by establishing an indoor tobacco smoking-free zone, practicing exclusive breastfeeding, and enhancing hygiene facilities.

Fuel type use and risk of respiratory symptoms: A cohort study of infants in the Northern region of Ghana

Little evidence exists about the association between fuel type use and risk of respiratory symptoms among infants; we aimed to evaluate this hypothesis through a cohort study in the Northern Region of Ghana. The study was carried out from April 2018 to May 2019. We recruited 28 weeks old pregnant women at selected hospitals and prospectively followed them at birth in the hospital ward to register their newborns and at homes when the baby had attained 3 to 7 months to collect data on respiratory symptoms of infants. A logistic regression model was used to investigate the odds of respiratory symptoms in infants. Exactly 1270 infants completed the study; the average age of women was 27.1 years and standard deviation of 5.1. The study found that infants of mothers who cooked with charcoal and those with firewood had increased odds of having cough with cold 4.10 (95% CI, 2.21-7.61) and 3.95 (95% CI, 2.06-7.58), increased odds of congestion, phlegm with cold by 3.89 (95% CI, 1.73-8.79) and 3.45 (95% CI, 1.44-8.26), increased odds of wheezing 4-14 days or nights by 1.68 (95% CI, 0.72-3.91) and 3.37 (95% CI, 1.41-8.04) and increased odds of seeking medical treatments in a health facility for chest illness by 3.97 (95% CI, 1.31-12.02) and 6.67 (95% CI, 2.14-20.77) in comparison with liquid petroleum gas respectively. Some significant predictors of respiratory infections were maternal malaria, hospitalisations of an infant after birth, residence, cooking location, composite breastfeeding, sharing of a bedroom with infant and air-conditioner or fan in the living room. Our findings indicate increased odds of infant respiratory symptoms in households using solid fuel in Ghana. Although our observational design precludes ascribing any causal relationships, our results are consistent with other studies suggesting clean fuel use during pregnancy and infancy may benefit this vulnerable age group.

Place of food cooking is associated with acute respiratory infection among under-five children in Ethiopia: multilevel analysis of 2005-2016 Ethiopian Demographic Health Survey data

Background

Globally, acute respiratory infections are among the leading causes of under-five child mortality, especially in lower-income countries; it is associated with indoor exposure to toxic pollutants from solid biomass fuel. In Ethiopia, 90% of the population utilizes solid biomass fuel; respiratory illness is a leading health problem. However, there is a paucity of nationally representative data on the association of household cooking place and respiratory infections. Besides, evidence on the variability in the infection based on the data collected at different times is limited. Therefore, this study is intended to assess the association of food cooking place with acute respiratory infections and the variability in households and surveys.

Methods

The current analysis is based on the Ethiopian Demographic and Health Survey data collected in 2005, 2011, and 2016 and obtained via online registration. The association of food cooking place with acute respiratory infection was assessed using multilevel modeling after categorizing all factors into child level and survey level, controlling them in a full model. The analyses accounted for a complex survey design using a Stata command “svy.”

Result

A total of 30,895 under-five children were included in this study, of which 3677 (11.9%) children had an acute respiratory infection, with 12.7% in 2005, 11.9% in 2011, and 11.1% in 2016. The risk of having an infection in under-five children in households that cooked food outdoors was 44% lower (AOR = 0.56, 95% CI = 0.40, 0.75) compared to those households that cooked the food inside the house. There was a statistically significant difference among the children among surveys to have an acute respiratory infection.

Conclusion

The risk of having children with acute respiratory infection is lower in the households of cooking food outdoor compared to indoor. The infection difference in different surveys suggests progress in the practices in either food cooking places or the fuel types used that minimize food cooking places location or the fuel types used that minimizes the risk. But, the infection is still high; therefore, measures promoting indoor cooking in a well-ventilated environment with alternative energy sources should take place.

A Qualitative Study on Family Role in the Care and Prevention of Acute Respiratory Infection Among Children in Primary Health Care

Background. Acute Respiratory Infection (ARI) is a common reason that parents seek help to primary health care. In 2016, almost 65% (64.4%) pneumonia and less than 36% (35.6%) non-pneumonia cases were found among the children in Malang. Members of families have important roles to play in individual's health, especially the children. The aim of this study was to explore the roles of family members in the care and prevention of children with ARI. Method. This was a qualitative study, with a phenomenological approach involving 12 informants. An in-depth interview was conducted on each informant having children with recurrent ARI during a space of 3 months in the primary health care. Information collected from the interviews were transcribed and analyzed into different themes. Results. The 4 themes identified include ARI in children, parent roles, influences of family members, and family problems. Different styles of parenting were established between the fathers and mothers also between the mothers and grandmothers on preventing ARI. The behavior of other family members impact both on the risk and prevention of ARI. Some of the identified problems capable of affecting children's health include inability to control the children, unstable income and the stressed condition of most mothers. Conclusion. Behavior of family members impacts on the prevention of ARI among the children. Problems within the family could affect the mothers' or caregivers' psychology, which might in turn impact on the care given to the children infected with ARI or in preventing it.

A pilot project: handwashing educational intervention decreases incidence of respiratory and diarrheal illnesses in a rural Malawi orphanage

Children who live in orphanages represent a population particularly vulnerable to transmissible diseases. Handwashing interventions have proven efficacy for reducing the rate of transmission of common infectious diseases. Few studies have analyzed the delivery of health interventions for children in orphanages in sub-Saharan Africa. To address this gap, we conducted an ecological assessment and piloted a handwashing intervention in an orphanage in rural Malawi, focusing on caregiver knowledge and behaviors, child handwashing behaviors, and disease incidence. A secondary study aim was to demonstrate program feasibility for a future randomized controlled trial. Orphanage caregivers participated in a three-module educational intervention on handwashing based on WHO recommendations and workshops on how to teach the curriculum to children. Seventeen orphanage caregivers and 65 children were monitored for handwashing behavior and child disease incidence. Friedman's tests were conducted to compare changes in caregiver knowledge and behaviors. Child handwashing behaviors and surveillance of child disease incidence were measured pre- and post-intervention. There were significant increases in caregiver hand hygiene knowledge. At six months post-intervention, handwashing with soap increased significantly among caregivers (p < 0.001) and was observed in children. The incidence of acute respiratory infections decreased from 30% to 6% post-intervention, resulting in an 80% decrease. The incidence of diarrhea decreased from 9.2% to 6.2% post-intervention, resulting in a 33% decrease. A brief educational intervention may improve handwashing knowledge and behaviors and help to decrease the incidence of common infectious diseases in an orphanage in rural Malawi. In addition, the caregiver uptake of the intervention demonstrated feasibility for future studies.

The burden and risks of pediatric pneumonia in Nigeria: A desk-based review of existing literature and data

BACKGROUND

Pneumonia is a leading killer of children under-5 years, with a high burden in Nigeria. We aimed to quantify the regional burden and risks of pediatric pneumonia in Nigeria, and specifically the states of Lagos and Jigawa.

METHODS

We conducted a scoping literature search for studies of pneumonia morbidity and mortality in under-5 children in Nigeria from 10th December 2018 to 26th April 2019, searching: Cochrane, PubMed, and Web of Science. We included grey literature from stakeholders' websites and information shared by organizations working in Nigeria. We conducted multivariable logistic regression using the 2016 to 2017 Multiple Cluster Indicators Survey data set to explore factors associated with pneumonia. Descriptive analyses of datasets from 2010 to 2019 was done to estimate trends in mortality, morbidity, and vaccination coverage.

RESULTS

We identified 25 relevant papers (10 from Jigawa, 8 from Lagos, and 14 national data). None included data on pneumonia or acute respiratory tract infection burden in the health system, inpatient case-fatality rates, severity, or age-specific pneumonia mortality rates at state level. Secondary data analysis found that no household or caregiver socioeconomic indicators were consistently associated with self-reported symptoms of cough and/or difficulty breathing, and seasonality was inconsistently associated, dependant on region.

CONCLUSION

There is a clear evidence gap around the burden of pediatric pneumonia in Nigeria, and challenges with the interpretation of existing household survey data. Improved survey approaches are needed to understand the risks of pediatric pneumonia in Nigeria, alongside the need for investment in reliable routine data systems to provide data on the clinical pneumonia burden in Nigeria.

Association of biomass fuel smoke with respiratory symptoms among children under 5 years of age in urban areas: results from Bangladesh Urban Health Survey, 2013

BACKGROUND

Little is known regarding the effect of exposure to biomass fuel smoke inhalation on respiratory symptoms in the Bangladeshi population which is a major health hazard in most of the developing countries. This study aims to explore the association between respiratory symptoms and biomass fuel smoke exposure among children under 5 years of age.

METHODS

Data were extracted from the Bangladesh Urban Health Survey conducted in 2013. A total of 10,575 mothers with at least one surviving children were selected. Respiratory symptoms among children under 5 years of age were considered as the primary outcome. Sequential multiple logistic regression models were used to observe the association between respiratory symptoms and biomass fuel smoke exposure adjusting the effect of residential factors and mother and child characteristics.

RESULTS

Around 40% of the mothers exclusively used biomass fuel irrespective of the kitchen location and 54% of them were habituated in indoor cooking. The prevalence of respiratory symptoms of under-five children among in-house and outdoor biomass fuel users was 23.0% and 21.9%, respectively. Results of fitted multiple logistic regression models showed that the odds of having respiratory symptoms among children under 5 years of age were increased due to in-house biomass fuel use [OR = 1.18; 95% CI, 1.04-1.36] compared with the non-biomass user. An increased risk of respiratory symptoms was also significantly associated with mother's birth complication [OR = 1.51; 95% CI, 1.36-1.67], non-government organization (NGO) membership of mothers [OR = 1.32; 95% CI, 1.16-1.51], age of the child (6-23m) [OR = 1.29; 95% CI, 1.10-1.52], and nutritional status (stunting) [OR = 1.18; 95% CI, 1.06-1.31].

CONCLUSION

This study found the use of in-house biomass fuel as a significant risk factor associated with respiratory symptoms of children under 5 years of age. More longitudinal studies should be designed to establish a causal relationship between HAP (household air pollution) and respiratory symptoms among children with more direct measures of HAP and clinical procedure.

Do fuel type and place of cooking matter for acute respiratory infection among Afghan children? Evidence from the Afghanistan DHS 2015

In Afghanistan, acute respiratory infection (ARI) is a leading cause of under-five mortality. Previous studies on the effects of cooking fuel on ARI have only looked at the types of cooking fuel, and not the effects of the location of the cooking place. The present study aimed to assess the effects of fuel type and place of cooking on the prevalence of ARI among under-five children in Afghanistan. Descriptive statistics and multilevel logistic regression analysis were performed for 31,063 children using data from the first round of the Afghanistan Demographic and Health Survey conducted in 2015. Overall, 13% of the children suffered from ARI symptoms in the 2 weeks before the survey, but this varied widely across the country. The multilevel analysis showed that, compared with households using clean cooking fuel in a separate building or outside, households using clean cooking fuel within the house and without a separate kitchen had a 32% lower risk [95% confidence interval (CI)=0.51-0.91] of having under-five children with ARI, and those using clean fuel in a separate kitchen in the house had a 17% lower risk (95% CI=0.67-1.03). On the other hand, households using polluting cooking fuel in the house without a kitchen had a 14% (95% CI=0.91-1.44) higher risk of having under-five children with ARI, and those using polluting cooking fuel in the house with a separate kitchen had a 5% (95% CI=0.85-1.30) higher risk, after adjusting for other covariates. The findings indicate that type of cooking fuel is not the only issue affecting ARI in children. Place of cooking (in a house with or without a separate kitchen versus outside) also affects the risk of ARI among under-five children. The study also found that mother's education and occupational status, community poverty and ethnicity are other important factors affecting the prevalence of ARI in under-five children in Afghanistan.

Prevalence, determinants and health care-seeking behavior of childhood acute respiratory tract infections in Bangladesh

Background

Acute respiratory infections (ARIs) are one of the leading causes of child mortality worldwide and contribute significant health burden for developing nations such as Bangladesh. Seeking care and prompt management is crucial to reduce disease severity and to prevent associated morbidity and mortality.

Objective

This study investigated the prevalence and care-seeking behaviors among under-five children in Bangladesh and identified factors associated with ARI prevalence and subsequent care-seeking behaviors.

Method

The present study analyzed cross-sectional data from the 2014 Bangladesh Demographic Health Survey. Bivariate analysis was performed to estimate the prevalence of ARIs and associated care-seeking. Logistic regression analysis was used to determine the influencing socio-economic and demographic predictors. A p-value of <0.05 was considered as the level of significance.

Result

Among 6,566 under-five children, 5.42% had experienced ARI symptoms, care being sought for 90% of affected children. Prevalence was significantly higher among children < 2 years old, and among males. Children from poorer and the poorest quintiles of households were 2.40 (95% CI = 1.12, 5.15) and 2.36 (95% CI = 1.06, 5.24) times more likely to suffer from ARIs compared to the wealthiest group. Seeking care was significantly higher among female children (AOR = 2.19, 95% CI = 0.94, 5.12). The likelihood of seeking care was less for children belonging to the poorest quintile compared to the richest (AOR = 0.03, 95% CI = 0.01, 0.55). Seeking care from untrained providers was 3.74 more likely among rural residents compared to urban (RRR = 3.74, 95% CI = 1.10, 12.77).

Conclusion

ARIs continue to contribute high disease burden among under-five children in Bangladesh lacking of appropriate care-seeking behavior. Various factors, such as age and sex of the children, wealth index, the education of the mother, and household lifestyle factors were significantly associated with ARI prevalence and care-seeking behaviors. In addition to public-private actions to increase service accessibility for poorer households, equitable and efficient service distribution and interventions targeting households with low socio-economic status and lower education level, are recommended.

Effectiveness of hand hygiene practices in preventing influenza virus infection in the community setting: A systematic review

Background

Hand hygiene is known to be an effective infection prevention and control measure in health care settings. However, the effectiveness of hand hygiene practices in preventing influenza infection and transmission in the community setting is not clear.

Objective

To identify, review and synthesize available evidence on the effectiveness of hand hygiene in preventing laboratory-confirmed or possible influenza infection and transmission in the community setting.

Methods

A systematic review protocol was established prior to conducting the review. Three electronic databases (MEDLINE, Embase and the Cochrane Library) were searched to identify relevant studies. Two reviewers independently screened the titles, abstracts and full-texts of studies retrieved from the database searches for potential eligibility. Data extraction and quality assessment of included studies were performed by a single reviewer and validated by a second reviewer. Included studies were synthesized and analyzed narratively.

Results

A total of 16 studies were included for review. Studies were of low methodological quality and there was high variability in study design, setting, context and outcome measures. Nine studies evaluated the effectiveness of hand hygiene interventions or practices in preventing laboratory-confirmed or possible influenza infection in the community setting; six studies showed a significant difference, three studies did not. Seven studies assessed the effectiveness of hand hygiene practices in preventing laboratory-confirmed or possible influenza transmission in the community setting; two studies found a significant difference and five studies did not.

Conclusion

The effectiveness of hand hygiene against influenza virus infection and transmission in the community setting is difficult to determine based on the available evidence. In light of its proven effectiveness in other settings, there is no compelling evidence to stop using good hand hygiene practice to reduce the risk of influenza infection and transmission in the community setting.

Household environment and symptoms of childhood acute respiratory tract infections in Nigeria, 2003-2013: a decade of progress and stagnation

BACKGROUND

Acute respiratory infections (ARIs) remains a disease of public health importance in Nigeria. Though, previous studies have identified factors associated with childhood ARI symptoms, the progress made in reducing the burden of this major childhood morbidity in the past decade in Nigeria has not been quantified. Therefore, this study describes the trends in the prevalence and factors associated with ARI symptoms among under-five (U5) children in Nigeria between years 2003 and 2013.

METHODS

A retrospective cross-sectional analysis of nationally representative data from the Nigeria Demographic and Health Surveys (NDHS) for years 2003, 2008 and 2013 was done. The study sample included women of reproductive age who had U5 children presenting with a cough accompanied with short rapid breaths in the last 2 weeks prior data collection. Data were analysed using complementary log regression model.

RESULTS

Prevalence of ARI symptoms were 10.3, 4.6 and 3.8% for years 2003, 2008 and 2013 respectively. The use of unclean cooking fuel was not associated with ARI symptom in 2003 and 2008, but in 2013 (OR = 2.50, CI: 1.16-5.42). Living in houses built with poor quality materials was associated with higher risk of ARI symptoms in 2008 (OR = 1.34, CI: 1.11-1.61) and 2013 (OR = 1.59, CI: 1.32-1.93). Higher risk of ARI symptoms was also associated with younger child's age, Northern regions and household wealth quintile between 2003 and 2013.

CONCLUSIONS

Though there has been a significant progress in the reduction of the prevalence of ARI symptoms between 2003 and 2013, the same could not be said of household environmental risk factors. Interventions to reduce the contributory effects of these factors to the occurrence of ARI symptoms should be instituted by government and other relevant stakeholders.

Environmental Risks Associated with Symptoms of Acute Respiratory Infection among Preschool Children in North-Western and South-Southern Nigeria Communities

The exposure-disease-stress model places young children in their physical and social contexts and considers the extent and intensity of associational links to symptoms of acute respiratory infection (ARI), taking in to account a range of biological, social, and environment components. This study uses the 2013 Nigeria Demographic and Health Survey to assess the individual and environmental risks present in the North-Western and South-Southern Nigerian communities and examines their associations with ARI symptoms. The descriptive findings show that the prevalence of ARI symptoms is significantly higher among preschool children in the North-Western province (5.7%) than in the South-Southern province (1.4%) (p < 0.001). In addition to regional differences, multilevel logistic models further indicate that the increased likelihood of a child suffering from ARI symptoms is significantly associated with the dry season (aOR 1.42; 95% CI: 1.02–1.97) and household poverty (aOR 1.42; 95% CI: 1.01–1.99), even after adjusting for the cooking fuel used and various other characteristics of the children, households, and communities. These findings underscore the importance of taking into account environmental risks when addressing specific regional variations in ARI symptoms, because these determinants differ between communities in Nigeria. As it is imperative to achieve minimum levels of child health, in order to improve economic development across regions, future health policies aiming to promote child health will benefit from taking a region-specific perspective into consideration.

Factors contributing to regional inequalities in acute respiratory infections symptoms among under-five children in Nigeria: a decomposition analysis

BACKGROUND

Acute respiratory infections (ARI) are major causes of morbidity and mortality in many low-income countries. Although factors associated with ARI symptoms in children under 5 years of age have been identified; however, variation in their prevalence resulting from regional-specific proximate determinants has received little attention. Therefore, we aim to investigate the specific regional determinants of overall and wealth-related inequality in children having ARI in Nigeria over a decade.

METHODS

We analyzed trends in development of ARI symptoms among children under 5 years of age in Nigeria using nationally representative cross sectional surveys carried out in 2003, 2008 and 2013. Overall- and household wealth index based- inequality in the distribution of prevalence of ARI symptoms were estimated by region using Gini index and Concentration Index, respectively. Multivariate logistic regressions for complex survey and decomposition analysis for both indexes were used to calculate percentual contribution.

RESULTS

We found a decreasing trend in development of ARI symptoms over the decade between regions. Children in South Western region had reduced likelihood of developing the symptoms. Concentration index (CI) for the prevalence of ARI symptoms over the years and across regions had negative values (all p < 0.05). Gini index (GI) varies from 0.21 in North East to 0.62 in South Western region. Furthermore, the mapping showed that the extent at which both inequalities contribute to ARI symptoms prevalence in each region is different. The four major sources of wealth-related inequalities were poor households, no maternal education, biomass cooking, and rural area. The major contributors to overall inequalities were having a child aged 6 to 23 months, having no maternal education, having no vaccination card, and having a high birth order/short birth interval.

CONCLUSIONS

Although ARI prevalence decreased over the decade, it has remained unequally distributed between regions and over the time. The sources of those inequalities are context sensitive. Thus, in future health promotion initiatives, it is imperative to account for regional variations in the distribution of ARI.
