Clinical and Epidemiological Determinants of Lower Respiratory Tract Infections in Hospitalized Pediatric Patients

Background

Lower respiratory tract infection (LRTI) is the main cause of pediatric mortality and morbidity in low- and middle-income countries.

Purpose

This study was carried out to determine the clinical and epidemiological characteristics of children with LRTI.

Method

A retrospective study was conducted on all pediatric patients who were hospitalized due to LRTI in Abuzar Hospital (Ahvaz, Iran) during one year. Incomplete medical records and children who were treated on an outpatient basis, as well as infants younger than 1 month of age, were excluded. The patients were evaluated in terms of epidemiological, clinical, and paraclinical characteristics.

Results

A total of 303 hospitalized children and infants were identified. Their mean age was 29.09 ± 38.96 months (range 1 month-15 years), and 59.4% of them were males. The highest frequency of patients was at the age below one year (50.8%, n = 154). Pneumonia and bronchitis were the most common LRTIs. Respiratory (54.6%) and neurological (21.6%) diseases were the most prevalent underlying medical conditions. Admission was more common in winter (n = 120, 39.6%) and spring (n = 79, 26.1%). The mean length of stay (LOS) in the hospital was 8.2 ± 5.5 days, and the overall mortality rate was 11.6%. In addition, 65 patients were severely underweight and 271 patients were malnourished. Moreover, there was a significant association between mortality and disease diagnosis (p < 0.05). Furthermore, there was a significant association between having an underlying disease and consanguineous parents (p < 0.01), as well as the frequency of hospitalization (p < 0.001).

Conclusion

Additional studies are required to determine factors contributing to disease severity among children with LRTI to develop appropriate preventive and therapeutic strategies.

Prevalence and Correlates of Undernutrition in Young Children Living in Urban Slums of Mumbai, India: A Cross Sectional Study

Background: Young children living in urban slums are vulnerable to malnutrition and subsequently poor health outcomes, but data on the correlates of stunting, underweight, wasting, and anemia specifically among 10-18 month-old children in India remain limited. Objective: In this analysis, we sought to describe the prevalence of and examine correlates for different markers of undernutrition, including stunting, underweight, and anemia among 10-18 month-old children living in urban slums, an understudied vulnerable group. Methods: Children and their mothers (n = 323) were screened for anthropometry, demographics, and complete blood counts for hemoglobin concentration between March and November 2017 (Clinicaltrials.gov ID: NCT02233764). Correlates included child and mother's age, sex, birth order, birth weight, illness episodes, hemoglobin concentration, family income, maternal height, and maternal education level. Risk ratios (RR, 95% CI) for binary outcomes (stunting, underweight, wasting and anemia) and mean differences (β, 95% CI) for continuous outcomes (anthropometric Z-scores, hemoglobin concentration) were calculated using multivariate binomial and linear regression (SAS 9.4). Results: The prevalence of stunting was 31.2%, underweight 25.1%, wasting (9.0%), and anemia (76%) among all children. Male children had a higher prevalence of poor growth indices and lower anthropometric Z-scores than females. Male sex, low birthweight, shorter maternal height, report of ≥1 episodes of illness within the past month, older maternal age, and birth order ≥2 were also associated with poor growth and anemia in multivariate models. Correlates of undernutrition were different among females and males. Female children had a 40% (20, 60%) higher risk of anemia associated with diarrhea, and male children who were firstborn had a 20% (0, 70%) lower risk of anemia. Conclusions: These results show that poor growth and anemia among young children is prevalent in urban slums of Mumbai, and that sex of the child may play an important role in informing interventions to address undernutrition.

Assessment of Malnutrition Risk in Canadian Pediatric Hospitals: A Multicenter Prospective Cohort Study

OBJECTIVE

To assess the prevalence, causes, and consequences of malnutrition, as well as the evolution of nutritional status, in Canadian pediatric health care institutions.

STUDY DESIGN

In this multicenter prospective cohort study, a total of 371 patients were recruited from pediatric hospitals in 5 Canadian provinces. Subjects were aged 1 month to 18 years; admitted to a medical, surgical, or oncology ward; and had a planned hospital stay of >48 hours. Data on demographics, medical condition, anthropometric measures, and dietary intake were collected. The Screening Tool Risk on Nutritional Status and Growth (STRONG_kids) and Subjective Global Nutritional Assessment (SGNA) were applied at admission. Malnutrition was defined as a weight-for-age, height-for-age, body mass index-for-age, or weight-for-length/height z score <-2 SD.

RESULTS

Among 307 subjects (median age, 5.3 years; median length of stay, 5 days), 19.5% were malnourished on admission. Both STRONG_kids and SGNA classifications were associated with baseline nutritional status. Mean weight-for-age z score was lower at discharge compared with admission (-0.14 vs -0.09; P < .01), and nearly one-half of all patients lost weight during their hospital stay. Only one-half of the children who were malnourished or screened as high risk of malnutrition were visited by a dietitian during their stay. The percentage of patients who lost weight during hospitalization was significantly greater in the group not visited by a dietitian (76.5 vs 23.5%; P < .01).

CONCLUSION

Nutritional status deterioration and malnutrition are common in hospitalized Canadian children. Screening tools, anthropometric measurements, and dietitian consultation should be used to establish adequate nutritional support.

Burden of Severe Acute Malnutrition in under-five Children (2-59 Months) Admitted in a Tertiary Care Hospital of Delhi

OBJECTIVE

The aim of the present study is to assess the burden of severe acute malnutrition (SAM) and other malnutrition in a tertiary care hospital in Delhi.

METHODS

All patients aged 2-59 months admitted from August 2012 to July 2014 were screened for malnutrition by anthropometry using standard techniques, and SAM was diagnosed as per guidelines [1, 2].

RESULTS

During the study period, 4520 children of age 2-59 months were admitted and complete data of 4354 children were available, which were analysed. Of these, 50.4% were underweight, 44.6% were stunted, 33.5% were wasted, 0.76% had oedematous malnutrition and 18.3% had SAM. Of all patients with SAM, 80% were <24 months old, with 54.1% males and 45.9% females. Moderate acute malnutrition was present in 21.4%. Associated co-morbidities were diarrhoea or respiratory infection or both.

CONCLUSION

Hospitals of Delhi have a high load of complicated SAM and need adequate infrastructure and facilities for management of these children.

Interventions to tackle malnutrition and its risk factors in children living in slums: a scoping review

CONTEXT

Children living in slums are at high risk of being malnourished. There are no published reviews on existing interventions promoting better nutrition for children living in slums and the risk factors for children's malnutrition. Improved understanding of the risk factors for malnutrition in slums communities and the impact of interventions on children's health can provide guidance to practitioners and decision-makers. The present review is designed to provide this information.

METHODS

The search included 30 electronic bibliographic databases and relevant eligible studies published up to December 2013.

RESULTS

The search located 1512 citations. Full text relevance screening was conducted on 226 studies and on abstracts for 16 studies. The final 58 unique studies included 22 on interventions and 38 on risk. All of the interventions were nutrition-specific, with nutritional intervention being the most dominant type. Seventy-three per cent of the interventions were assessed effective.

CONCLUSION

The findings stressed the gaps in knowledge in terms of quality assessment and programmatic recommendations to identify children who are the most at risk of malnutrition to appropriately target interventions. Finally, the review helped to inform a systematic review (Cochrane Systematic review protocol 2015) that will examine the impact of interventions on outcome measures.
