Factors associated to breastfeeding in the first hour of life: systematic review

OBJECTIVE

To identify independent risk factors for non-breastfeeding within the first hour of life.

METHODS

A systematic review of Medline, LILACS, Scopus, and Web of Science electronic databases, till August 30, 2013, was performed without restrictions on language or date of publishing. Studies that used regression models and provided adjusted measures of association were included. Studies in which the regression model was not specified or those based on specific populations regarding age or the presence of morbidities were excluded.

RESULTS

The search resulted in 155 articles, from which 18 met the inclusion criteria. These were conducted in Asia (9), Africa (5), and South America (4), between 1999 and 2013. The prevalence of breastfeeding within the first hour of life ranged from 11.4%, in a province of Saudi Arabia, to 83.3% in Sri Lanka. Cesarean delivery was the most consistent risk factor for non-breastfeeding within the first hour of life. “Low family income”, “maternal age less than 25 years”, “low maternal education”, “no prenatal visit”, “home delivery”, “no prenatal guidance on breastfeeding” and “preterm birth” were reported as risk factors in at least two studies.

CONCLUSIONS

Besides the hospital routines, indicators for low socioeconomic status and poor access to health services were also identified as independent risk factors for non-breastfeeding within the first hour of life. Policies to promote breastfeeding, appropriate to each context, should aim to reduce inequalities in health.     

Determinants of breastfeeding initiation within the first hour of life in a Brazilian population: cross-sectional study

Background  

Breastfeeding within the first hour of life is a potential mechanism for health promotion. The purpose of this study was to evaluate the prevalence of breastfeeding initiation within the first hour of life in Feira de Santana, Bahia, Brazil, between 2004 and 2005, and investigate the influence of maternal, child and prenatal factors on this practice.     

Factors associated with exclusive breastfeeding in Accra, Ghana

OBJECTIVE: To assess factors associated with exclusive breast-feeding (EBF) in Accra, Ghana. DESIGN, SUBJECTS, SETTING: Data on current and past infant feeding patterns, sociodemographic, biomedical and biocultural factors were collected using a cross-sectional design, from a sample of 376 women with infants 0-6 months, attending maternal and child health (MCH) clinics in Accra. EBF was defined in two ways: (a) based on a 24-h recall, and (b) based on a recall of liquids or foods given since birth. RESULTS: Although 99.7% of mothers were currently breastfeeding (BF), only half (51.6%) of them EBF their infants. About 98% of participants had heard about EBF, and 85.6% of them planned to EBF on delivery. Based on 'since birth' EBF, planned EBF on delivery was associated with higher likelihood of EBF (OR=2.56; 95% CI, 1.06-6.17) and delivery at a hospital/polyclinic was associated with a two times higher likelihood of EBF (OR=1.96; 95% CI, 1.08-3.54). Women living in their own houses were more likely to EBF (OR=3.96; 95% CI, 1.02-15.49) than those living in rented accommodations and family houses. Those with a more positive attitude towards EBF were more likely to EBF (OR=2.0; 95% CI, 1.11-3.57) than their counterparts with more negative attitudes. The '24-h recall' EBF model yielded similar results. CONCLUSION: In this population, EBF was associated with delivery at hospital/polyclinic, having secondary school education, intention to EBF prior to delivery, owning a home and having a positive attitude to EBF.     

Factors associated with exclusive breastfeeding: the role of primary health care

The aim of this study was to assess the association between promotion, protection, and support for breastfeeding in primary health care services and prevalence of exclusive breastfeeding in the first six months of life. A cross-sectional study was conducted in a representative sample of 1,029 mothers of infants younger than six months treated at primary health care facilities in the city of Rio de Janeiro, in southeastern Brazil. Prevalence ratios (PR) were estimated by Poisson regression. Prevalence of exclusive breastfeeding was 58.1%. Factors associated with increased prevalence of exclusive breastfeeding were: white skin color (PR = 1.20; 95% CI: 1.05-1.36); schooling (PR = 1.19; 95% CI: 1.05-1.35); marital status (married or in common-law marriage) (PR = 1.72; 95% IC:1.02-2.90); previous breastfeeding (PR = 1.27; 95% CI: 1.08-1,49); exclusive breastfeeding at the time of hospital discharge (PR = 2.01; 95% CI: 1.20-3.36); group support for the mother (PR = 1.14; 95% CI: 1.01-1.28); and orientation on breastfeeding (PR = 1.20; 95% CI: 1.08-1.33). Prevalence of exclusive breastfeeding decreased 17% per month in the infant's life. Support groups and orientation by primary health care for breastfeeding were associated with increased exclusive breastfeeding prevalence.     

Hemoglobin concentration, breastfeeding and complementary feeding in the first year of life

OBJECTIVE: To assess the relationship between hemoglobin concentration and breastfeeding and complementary feeding during the first years of life. METHODS: Cross-sectional study with 553 children under age 12 months, who attended public healthcare facilities. Hemoglobin concentration was measured by the cyanmethaemoglobin method, using the HemoCue system. Associations of interest were analyzed through multiple linear regression. RESULTS: Hemoglobin concentrations compatible with anemia were identified in 62.8% of the children studied, with greater occurrence among the 6-12 months age group (72.6%). Exclusive breastfeeding during the first six months of life was associated with the highest levels of hemoglobin. The remaining feeding regimes were associated with different levels of reduction in hemoglobin levels, which became compatible with anemia in children fed with formula (p=0.009). Tea and/or water consumption was associated with a reduction in hemoglobin concentration of 0.76 g/dl (p<0.001) among children under age 6 months. For children aged 6-12 months, hemoglobin concentrations increased significantly with the consumption of sugar (p=0.017) and beans (p=0.018), and decreased significantly with the consumption of fruit (p<0.001). CONCLUSIONS: Exclusive breastfeeding until age 6 months and continuation of breastfeeding after this age, combined with qualitatively and quantitatively appropriate feeding may contribute towards an increase in hemoglobin concentration in the first year of life.     

Infant feeding patterns during the first year of life in Denmark: Factors associated with the discontinuation of breast-feeding

We prospectively studied 500 infants born consecutively in a university-affiliated community hospital in Copenhagen, Denmark, over the first 12 months of life using a detailed monthly mailed questionnaire (overall response RATE = 73%) which focused on feeding practices and illnesses. Seventy-seven percent of respondents breast-fed their infants at 1 month of life compared to 19% at 12 months of life. Analysis of breast-feeding behavior using survival analysis showed that 50% of the mothers who breast-fed since the first month of their infant's life were still breast-feeding at 7 months of life. Also, there was a greater than two-fold increase in the rate of discontinuation of breast-feeding for infants in daycare compared to infants not attending daycare (RR = 2.08, 95% CI = 1.43, 3.01). Discontinuation of breast-feeding was not significantly associated with the number of children in the family or with social class.

These results give insight into infant feeding patterns in a developed country and suggest that: (1) breast-feeding is the dominant method of feeding during the infant's first year of life, and (2) the rate of discontinuation of breast-feeding is increased by the entry of these infants into daycare.     

Factors associated with weaning in the first 3 months postpartum

OBJECTIVE: To determine the demographic, behavioral, and clinical factors associated with breastfeeding termination in the first 12 weeks postpartum. STUDY DESIGN: This was a prospective cohort study. POPULATION: Breastfeeding women in Michigan and Nebraska were interviewed by telephone at 3, 6, 9, and 12 weeks postpartum or until breastfeeding termination. OUTCOMES MEASURED: We measured associations of demographic, clinical, and breastfeeding variables with weaning during the first 12 weeks postpartum. RESULTS: A total of 946 women participated; 75% breastfed until 12 weeks. Women older than 30 years and women with at least a bachelor's degree were more likely to continue breastfeeding in any given week. Mastitis, breast or nipple pain, bottle use, and milk expression in the first 3 weeks were all associated with termination. Beyond 3 weeks, women who expressed breast milk were 75% less likely to discontinue breastfeeding than women who did not. Women who used a bottle for some feedings during weeks 4 to 12 were 98% less likely to discontinue breastfeeding than women who did not use a bottle. "Not enough milk" was the most common reason given for termination in weeks 1 through 3 (37%) and weeks 4 through 6 (35%); "return to work" was the most common reason given in weeks 7 through 9 (53%) and weeks 10 through 12 (58%). CONCLUSIONS: Younger women and less educated women need additional support in their breastfeeding efforts. Counseling and assistance should be provided to women with pain and mastitis. Exclusive breastfeeding for the first 3 weeks should be recommended. After the first 3 weeks, bottles and manual expression are not associated with weaning and may improve the likelihood of continuing breastfeeding, at least until 12 weeks.     

Factors associated with low quality of life in schizophrenia

Interest in quality of life in mental health care has been stimulated by the deinstitutionalization of psychiatric patients as well as a parallel interest in understanding the scope of their daily lives. This study aims to investigate the socio-demographic and clinical variables related to low quality of life, using a cross-sectional design to evaluate quality of life by means of the QLS-BR scale. We interviewed a sample of 123 outpatients from a reference mental health center in Divinópolis, Minas Gerais State, Brazil, clinically diagnosed with schizophrenia. Univariate and multivariate logistic regression analyses were carried out. The results showed that low quality of life is associated with one or more of the following: male gender, single marital status, low income plus low schooling, use of three or more prescribed psychoactive drugs, psychomotor agitation during the interview, and current follow-up care. The study identifies plausible indicators for the attention and care needed to improve psychiatric patient treatment.     

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.     

Factors associated with interruption of exclusive breastfeeding in low birth weight infants receiving primary care

This study aimed to identify factors associated with interruption of exclusive breastfeeding (EBF) in low birth weight infants receiving primary care. This was a cross-sectional study of 170 infants treated at primary care units on the urban periphery of S?o Paulo, Brazil. The sample included infants with birth weight ≤ 2,500g (including twins) and 5-minute Apgar ≥ 7, followed until the third month of life, and excluded infants/mothers with complications that would impede EBF, besides infant/maternal deaths. Data were collected from forms completed during consultations and patient records. Prevalence ratios were obtained by Poisson regression. The following factors were associated with interruption of EBF in the first three months of life: maternal age ≤ 18 years; informal employment (protective factor); alcohol intake during pregnancy; < 6 prenatal visits; multiple gestations; birth weight ≤ 2,000g; difficulty breastfeeding in the first month; complaints in breastfeeding during the first month; and use of pacifiers in the first two months. Prior knowledge of these factors can help plan measures and policies to increase EBF rates among low birth weight infants.     

Factors associated with quality of life in older adults in the United States

Purpose  

According to the World Health Organization, quality of life (QOL) includes physical and mental health, emotional well-being, and social functioning. Using an adaptation of Andersen’s behavioral model, we examined the associations between the three dimensions of QOL and needs and health behaviors in a nationally representative sample of adults 65 years and older.     

Bottle feeding during the first month of life: determinants and effect on breastfeeding technique

OBJECTIVE: To assess incidence rate and determinants of bottle feeding during the first month of life, and its potential effects on breastfeeding technique. METHODS: A nested cross-sectional study was conducted in a contemporary cohort in the city of Porto Alegre, Southern Brazil, between June and November 2003. A total of 211 pairs of healthy mothers and infants were followed up for a month. The effect of bottle feeding on breastfeeding technique was assessed by comparing five items unfavorable to mother-infant positioning and three items unfavorable to infant latch-on; and the average number of unfavorable items between the pairs who started bottle feeding in the first month of life and those who did not. A logistic regression analysis was carried out according to a hierarchical model. RESULTS: By Day 7, 21.3% of infants were bottle-fed and 46.9% were bottle-fed by Day 30. Living with maternal grandmother was associated with bottle feeding at Days 7 and 30. Maternal age <20 years, and nipple trauma at the maternity hospital were also associated with bottle feeding at Day 7. Other factors associated with bottle feeding at Day 3 were pacifier use at Day 7 and nipple trauma at Day 7. There was no association between the breastfeeding technique taught at the maternity hospital and subsequent bottle feeding. However, at Day 30, the breastfeeding technique was found to be more adequate among exclusively breast-fed infants than those who were also bottle fed. CONCLUSIONS: The study results showed that bottle feeding was quite widespread in the first month of life, mainly in infants born to teenage mothers, with nipple trauma, whose maternal grandmothers were living in the same household, and who were using pacifiers. Besides the already recognized negative effects, bottle feeding may negatively affect breastfeeding technique.     

Symptoms of postpartum depression and early interruption of exclusive breastfeeding in the first two months of life

This study evaluates the association between postpartum depression and interruption of exclusive breastfeeding in the first two months of life. Cohort study of 429 infants < or = 20 days of age to four primary health care units in Rio de Janeiro, Brazil. Interruption of exclusive breastfeeding (outcome) was defined as the introduction of water, other types of liquids, milk, or formulas or any food. Postpartum depression was assessed using the Edinburgh Post-Natal Depression Scale. Associations between variables were expressed as prevalence ratios (baseline) and risk ratios (follow-up), with their respective 95% confidence intervals, estimated by Poisson regression with robust variance. Children of mothers with postpartum depressive symptoms were at higher risk of early interruption of exclusive breastfeeding in the first and second months of follow-up (RR = 1.46; 95%CI: 0.98-2.17 and RR = 1.21; 95%CI: 1.02-1.45, respectively). Considering mothers that were exclusively breastfeeding at the first month, postpartum depression was not associated with interruption of exclusive breastfeeding in the second month (RR = 1.44; 95%CI: 0.68-3.06). The results indicate the importance of maternal mental health for the success of exclusive breastfeeding.     

Airborne endotoxin is associated with respiratory illness in the first 2 years of life

To determine the influence of endotoxin on the incidence of acute respiratory illness during the first 2 years of life, we carried out a longitudinal follow-up study, beginning at birth, of 332 children born in Prince Edward Island, Canada. We measured 5-day averaged air endotoxin in the homes of children, whose parents provided information by daily symptom diaries and twice-monthly telephone contact for up to 2 years. Endotoxin concentration was 0.49 +/- 3.49 EU/m3 (geometric mean +/- geometric SD), and number of annualized illness episodes was 6.83 +/- 2.80 (mean +/- SD). A doubling of the air endotoxin concentration was associated with an increase of 0.32 illness episodes per year (p = 0.0003), adjusted for age, year of study, breast-feeding, environmental tobacco smoke, child care attendance, indoor temperature, and income. Indoor mold surface area and fungal ergosterol were not significantly associated with endotoxin. Airborne endotoxin appears to be a risk factor for clinically symptomatic respiratory illnesses during the first 2 years of life independent of indoor fungus.     

Midwifery factors associated with successful breastfeeding

Background It is well recognized that breast milk is the best form of nutrition for babies. However, many women do not breastfeed or give up soon after birth. Some report feeling unsupported in the post‐natal period and many stop breastfeeding earlier than they would have wished. This study aimed to estimate the separate effects of midwifery factors in the overall context of sociodemographic and clinical influences on breastfeeding. Methods Data from a national survey conducted in England in 2006 were used. Questionnaires were sent to a random sample of 4800 new mothers (63% response rate). Questions relating to infant feeding allowed calculation of rates of initiation of breastfeeding and rates of exclusive and any breastfeeding in the first few days and at 3 months. Univariate analyses were carried out to estimate the associations between sociodemographic, clinical and midwifery factors and breastfeeding. Logistic regression was used to estimate the specific effects of midwifery factors, while adjusting for other significant variables. Results The most powerful explanatory factor was antenatal feeding intention. Maternal age, absence of clinical problems in the baby and a short post‐natal stay were important in the early days. At 3 months, breastfeeding was associated with sociodemographic and intrapartum factors. At all stages, breastfeeding was significantly associated with either receiving consistent advice, practical help and/or active support and encouragement from midwives. Conclusions The antenatal decision about infant feeding is the most powerful predictor of infant feeding behaviour. Some sociodemographic and clinical factors are also important influences on breastfeeding. However, after adjusting for these, midwifery factors are still influential.     

Factors associated with health-related quality of life in chronic leg ulceration

Background

Individuals with chronic leg ulceration may have significantly impaired health-related quality of life (HRQOL) due to pain, impaired mobility, poor sleep, depression, restricted work capacity, and social isolation. The study purpose was to examine the associations among sociodemographic and clinical factors and HRQOL in a large sample of community-dwelling adults being treated for leg ulcers.

Methods

Data are from the cross-sectional baseline assessment of the Canadian Bandaging Trial, a multi-center, randomized controlled trial conducted to assess time to healing with two forms of high-compression bandaging. All participants received a comprehensive, standardized clinical assessment, and completed the 12-item Short Form (SF-12) and McGill Pain Questionnaire. SF-12 data were compared to age- and sex-adjusted norms, and multivariable logistic regression was used to identify factors associated with whether individuals were below, or at/above their normative values on the physical and mental component summary (PCS, MCS).

Results

Of 424 individuals enrolled over a 50-month period, 407 (96 %) completed the SF-12. Mean age was 65 ± 17 years, and 55 % were women. Mean PCS was 39.1 ± 9.9 with 91 (22.4 %) scoring at/above the mean value for their age and sex; equivalent values for the MCS were 51.4 ± 9.9 and 209 (51.4 %). Higher levels of pain, younger age, larger size and longer duration of ulcer, and limited mobility were associated with poorer HRQOL.

Conclusions

Findings confirm the considerable burden of illness associated with leg ulcers. Given the chronic and recurring nature of the condition, strategies focused on improving HRQOL and healing are needed for this vulnerable population.     

Factors associated with the academic success of first year Health Science students

The academic success of students is a priority for all universities. This study identifies factors associated with first year academic success (performance and retention) that can be used to improve the quality of the student learning experience. A retrospective cohort study was conducted with a census of all 381 full time students enrolled in the Bachelor of Health Science at The University of Western Australia since the inception of the course in the year 2000. Factors found to be associated with successful academic performance were high matriculation score, female sex, non-Indigenous status, attendance at a government secondary school, upfront payment of university fees and completion of secondary school English Literature. The most influential factor on first year academic performance was a high matriculation score. Retention into second year was found to be influenced by participation in the university mentor scheme, non-Indigenous status and first year university marks. The factor of most influence on student retention was first year university marks. Valuable information about the performance and retention of first year Bachelor of Health Science students is provided in this study which is relevant to the operational priorities of any university.     

Factors associated with health-related quality of life among hemodialysis patients in the DOPPS

Objective To identify modifiable factors associated with health-related quality of life (HRQOL) among chronic hemodialysis patients. Methods Analysis of baseline data of 9,526 hemodialysis patients from seven countries enrolled in phase I of the Dialysis Outcomes and Practice Patterns Study (DOPPS). Using the Kidney Disease Quality of Life Short Form (KDQOL-SF^TM), we determined scores for 8 generic scale summaries derived from these scales, i.e., the physical component summary [PCS] and mental component summary [MCS], and 11 kidney disease- targeted scales. Regression models were used to adjust for differences in comorbidities and sociodemographic and treatment factors. The Benjamini–Hochberg procedure was used to correct P-values for multiple comparisons. Results Unemployment and psychiatric disease were independently and significantly associated with lower scores for all generic and several kidney disease-targeted HRQOL measures. Several other comorbidities, lower educational level, lower income, and hypoalbuminemia were also independently and significantly associated with lower scores of PCS and/or MCS and several generic and kidney disease-targeted scales. Hemodialysis by catheter was associated with significantly lower PCS scores, partially explained by the correlation with covariates. Conclusion Associations of poorer HRQOL with preventable or controllable factors support a greater focus on psychosocial and medical interventions to improve the well-being of hemodialysis patients.
