Higher Frequency of Fruit Intake Is Associated With a Lower Risk of Constipation in Hemodialysis Patients: A Multicenter Study.

OBJECTIVES: Constipation is a multifactorial gastrointestinal disorder commonly found in hemodialysis (HD) patients. In this multicenter cross-sectional study, we aimed to evaluate the prevalence and factors associated with constipation, including the frequency of dietary fiber intake. METHODS: HD patients from 4 dialysis clinics were invited. Participants answered a questionnaire which included Roma IV criteria to assess constipation status, use of medications, and lifestyle habits. A food frequency questionnaire with 7 response options on the main dietary fiber sources (fruits, vegetables, legumes, whole grains, and seeds) was also applied. Answers were transformed into a score to estimate the weekly intake frequency, and every score point corresponded to one time per week. Demographical and laboratory data were obtained from medical records. Univariate analysis was used to compare participants according to constipation status, and variables with P < .20 were included in the regression analysis model. RESULTS: Three hundred five HD patients were included (male: 51%; age: 52.2 ± 14.7 years old; HD vintage: 46 (19-82) months). Ninety-three participants had constipation (30.5%). Median (interquartile) food frequency questionnaire scores were as follows: fruits: 6 (2-14); vegetables: 6 (3-10); legumes: 3 (1-7); whole grain: 0 (0-1); and seeds: 0 (0-0). In univariate analysis, participants with constipation were significantly older, had lower literacy, higher prevalence of diabetes, and lower total beverage intake. The logistic regression analysis model also included body mass index, wheelchair need, sedentarism, fruits score, and seeds score (all with P < .20 in the univariate analysis). The independent predictors of constipation were diabetes (odds ratio = 1.96, 95% confidence interval 1.07-3.6, P = .03) and fruits intake score (odds ratio = 0.95, 95% confidence interval 0.91-0.99, P = .04). CONCLUSIONS: Almost one-third of the participants had constipation. The independent determinants of constipation were diabetes and lower frequency of fruit intake. Nutritional counseling to increase fiber intake can potentially decrease the prevalence of constipation in this population.

Predictors of excess birth weight in Brazil: a systematic review.

OBJECTIVE: To describe the main predictors for excess birth weight in Brazilian children. DATA SOURCES: Systematic review carried out in the bibliographic databases: PubMed/MEDLINE, Cochrane, Scopus, Web of Science, and LILACS. The research in the gray literature was performed using the Google Scholar database. The bias risk analysis was adapted from the Downs and Black scale, used to evaluate the methodology of the included studies. DATA SYNTHESIS: Using the classifications of fetal macrosomia (>4.000g or ≥4.000g) and large for gestational age (above the 90th percentile), 64 risk factors for excess birth weight were found in 33 scientific articles in the five regions of the country. Of the 64 risk factors, 31 were significantly associated with excess birth weight, with excess gestational weight gain, pre-gestational body mass index ≥25kg/m2, and gestational diabetes mellitus being the most prevalent. CONCLUSION: The main predictors for excess birth weight in Brazil are modifiable risk factors. The implementation of adequate nutritional status in the gestational period and even after childbirth appears to be due to the quality and frequency of the follow-up of the mothers and their children by public health agencies.

Resumo Objetivo: Descrever os principais preditores para o excesso de peso ao nascer em crianças brasileiras. Fontes dos dados: Revisão sistemática feita nos bancos de dados bibliográficos: PubMed/Medline, Cochrane, Scopus, Web of Science e Lilacs. A pesquisa na literatura cinzenta foi feita na base de dados Google Acadêmico. A análise do risco de viés foi adaptada da escala de Downs e Black, usada para avaliar a metodologia dos estudos incluídos. Síntese dos dados: Com o uso das classificações macrossomia fetal (> 4.000 g ou ≥ 4.000 g) e grande para idade gestacional acima do percentil 90, foram encontrados 64 fatores de risco para excesso de peso ao nascer em 33 artigos científicos nas cinco regiões do país. Dos 64 fatores de risco, 31 foram significativamente associados a excesso de peso ao nascer, os mais prevalentes foram ganho de peso gestacional excessivo, índice de massa corporal pré-gestacional ≥25 kg/m2 e diabetes mellitus gestacional. Conclusão: Os principais preditores para o excesso de peso ao nascer no Brasil são fatores de risco modificáveis. O estabelecimento de um estado nutricional adequado no período gestacional e mesmo após o parto parece ser a qualidade e a frequência do acompanhamento dos órgãos de saúde junto às mães e seus filhos.
