The Determinants of Complementary Feeding Introduction Vary According to the Type of Food and Infants' Ages: A Cohort Study-ClaB, Brazil.

INTRODUCTION: Food inadequacies in the first 6 months of life are considered a global problem, with an emphasis on early complementary feeding introduction (CFI). This study aimed to identify the determinants of CFI. METHODS: A birth cohort study (N = 641). Data on infant feeding was collected before 30 days, and at 2, 4, and 6 months of age and, at baseline, data regarding socioeconomic status, demographics, maternal and infant health, obstetric history, and infant care. The hypothesis was that the risk determinants for early CFI vary according to the type of food and the age range of this introduction. Twelve Cox regression models were fit with four outcomes (formula; other types of milk; other beverages; and solid/semi-solid foods) considering three different age ranges of the infant at their introduction (< 2 months, 2-4 months, and 4-6 months). RESULTS: The introduction of the four food groups analyzed was early (median ages of introduction: formulas = 45 days; other milks = 135 days; other beverages = 120 days; solids and semi-solids = 135 days). The determinants that increased the risk of introducing formulas before 2 months were: primiparity, employed without maternity leave, mothers with unsatisfactory prenatal counseling and those who had cesarean sections. Not living with a partner, infant pacifier use at 2 months of age had a higher risk of introducing formula between 2 and 4 months of age. Non-white skin color, more than 35 years old, low maternal education, and lower family income increased the risk of introducing other types of milk between 2 and 4 months of age. Between 4 and 6 months of age, adolescent and low education level mothers had a higher risk of introducing other types of milk, unemployed was a protective factor against the introduction of other foods and beverages in this age group. CONCLUSIONS: The determinants of early CFI varied according to the type of food and the age of introduction.

Smoking during pregnancy and harm reduction in birth weight: a cross-sectional study.

BACKGROUND: Different studies have shown the advantages of abstinence from cigarette smoking during pregnancy to promote full fetal development. Given that pregnant women do not always abstain from smoking, this study aimed to analyze the effect of different intensities of smoking on birth weight of the newborn. METHODS: A cross-sectional study was adopted to explore smoking in a population of pregnant women from a medium-sized city in São Paulo state, Brazil, who gave birth between January and June of 2012. Data were collected from maternal and pediatric medical files and, where data were absent, they were collected by interview during hospitalization for delivery. For data analysis, the effect of potential confounding variables on newborn birth weight was estimated using a gamma response model. The effect of the identified confounding variables was also estimated by means of a gamma response regression model. RESULTS: The prevalence of smoking during pregnancy was 13.4% in the study population. In full-term infants, birth weight decreased as the category of cigarette number per day increased, with a significant weight reduction as of the category 6 to 10 cigarettes per day. Compared with infants born to non smoking mothers, mean birth weight was 320 g lower in infants whose mothers smoked 6 to 10 cigarettes per day and 435 g lower in infants whose mothers smoked 11 to 40 cigarettes per day during pregnancy. CONCLUSIONS: Based on the study results and the principle of harm reduction, if a pregnant woman is unable to quit smoking, she should be encouraged to reduce consumption to less than six cigarettes per day.

Role of dietary food intake patterns, anthropometric measures, and multiple biochemical markers in the development of pregnancy-specific urinary incontinence in gestational diabetes mellitus.

OBJECTIVES: The aim of this study was to assess maternal dietary food intake patterns, anthropometric measures, and multiple biochemical markers in women with gestational diabetes mellitus and pregnancy-specific urinary incontinence and to explore whether antedating gestational diabetes mellitus environment affects the pregnancy-specific urinary incontinence development in a cohort of pregnant women with gestational diabetes mellitus and pregnancy-specific urinary incontinence. METHODS: Maternal dietary information and anthropometric measurements were collected. At 24 wk of gestation, with a fasting venipuncture sample, current blood samples for biochemical markers of hormones, vitamins, and minerals were analyzed. The groups were compared in terms of numerical variables using analysis of variance for independent samples followed by multiple comparisons. RESULTS: Of the 900 pregnant women with complete data, pregnant women in the gestational diabetes mellitus pregnancy-specific urinary incontinence group had higher body mass index during pregnancy, arm circumference, and triceps skinfold than the non-gestational diabetes mellitus continent and non-gestational diabetes mellitus pregnancy-specific urinary incontinence groups, characterizing an obesogenic maternal environment. Regarding dietary food intake, significant increases in aromatic amino acids, branched-chain amino acids, dietary fiber, magnesium, zinc, and water were observed in pregnancy-specific urinary incontinence group compared with the non-gestational diabetes mellitus continent group. Serum vitamin C was reduced in the gestational diabetes mellitus pregnancy-specific urinary incontinence group compared with the non-gestational diabetes mellitus pregnancy-specific urinary incontinence group. CONCLUSIONS: This study emphasizes the necessity for a comprehensive strategy for gestational diabetes mellitus women with pregnancy-specific urinary incontinence in terms of deviation in maternal adaptation trending toward obesity and maternal micronutrients deficiencies.

Complementary feeding practices to children during their first year of life.

This study aimed to investigate complementary feeding practices during children's first year of life in Botucatu, SP, Brazil. Practices were described according to the age range and the breastfeeding (BF) practice. Data were collected during a multi-vaccination campaign through the interview of 1,238 individuals who accompanied children younger than one year old being vaccinated. Differences associated with the BF situation were identified by the chi-square test and Fisher's exact test. The early introduction of complementary food was observed, which led to the low frequency of exclusive breastfeeding (36.9% <4 months). Children younger than 4 months old consumed tea (30.7%); children between 4 and 6 months old consumed fruits (54.1%), soups (39.9%) and home-made food (19.2%). Juice was offered only to 15.2% of children younger than 4 months old who were completed weaned, 60% of the children was offered water. Data show that the consistence of the food consumed was inappropriate: children between 6 and 8 months old were offered the family's regular food (48.8%) and children older than 8 months (71.6%) were offered soup. Therefore, interventions focused on complementary feeding are justified on the city.

Factors associated with exclusive breastfeeding in children under four months old in Botucatu-SP, Brazil.

This study aimed to identify factors associated with exclusive breastfeeding (AME) and the reasons mothers presented to introduce complementary feeding in the first four months of life. A total of 380 mothers (92.2%) of children under four months old vaccinated in a Multi-vaccination Campaign were interviewed. To identify factors associated to AME, univariate and multiple logistic regressions analyses were performed. Thirty-eight percent of the children were on AME; 33.4% consumed cow milk; 29.2% tea; and 22.4% water. The mothers justified introduction of cow milk by factors related to quantity/quality of maternal milk and "necessity" of the child. The use of a pacifier (odds ratio=2.63; CI95%=1.7-4.06) and difficulty to breastfeed (odds ratio=1.57; CI95%=1.02-2.41) were associated with the absence of AME. The populational attributable risk percentage for the use of a pacifier was estimated at 46.8 %. Thus, modifiable risk factors were associated with AME interruption.

[Breast feeding in a population attended by the family health program--FHP]. / Situação do aleitamento materno em população assistida pelo programa de saúde da família--PSF.

This study aimed to identify the prevalence of different types of breastfeeding and how they relate to maternal variables in the municipality of Conchas, São Paulo, Brazil, which is fully covered by the family health program. We collected information about the current eating habits of children under one year old who were attended during the 2003 Multivaccination Campaign. Associations were submitted to the chi-square test, adopting p<0.05 as the critical level. The prevalence rates for exclusive breastfeeding (EB) and predominant breastfeeding (PB) in 4-month-olds and younger were 25.4% and 44.4%, respectively, and 66.7% of the children under one were still being breastfed. Prevalence for EB in 6-month-olds and younger was heterogeneous, ranging from 7.4 to 41.2% according to the children's region of origin in the FHP. Difficulties at the beginning of breastfeeding were associated with lower prevalence rates for EB and PB. These results show a situation far from WHO recommendations and from that situation in which there is evidence that children's health receives maximum protection, reiterate the need to support mothers in the early puerperal period and demonstrate the importance of diagnoses separated per regions for actions aimed at promoting breastfeeding.
