The combined effect of employment status and transcultural marriage on breast feeding: a population-based survey in Taiwan

Risk factors for self-reported insufficient milk during the first 6 months of life: A systematic review

The objective of this systematic review was to identify multifactorial risk factors for self-reported insufficient milk (SRIM) and delayed onset of lactation (DOL). The review protocol was registered a priori in PROSPERO (ID# CDR42021240413). Of the 120 studies included (98 on SRIM, 18 on DOL, and 4 both), 37 (31%) studies were conducted in North America, followed by 26 (21.6%) in Europe, 25 (21%) in East Asia, and Pacific, 15 (12.5%) in Latin America and the Caribbean, 7 (6%) in the Middle East and North Africa, 5 (4%) in South Asia, 3 (2.5%) in Sub-Saharan Africa, and 2 (1.7%) included multiple countries. A total of 79 studies were from high-income countries, 30 from upper-middle-income, 10 from low-middle-income countries, and one study was conducted in a high-income and an upper-middle-income country. Findings indicated that DOL increased the risk of SRIM. Protective factors identified for DOL and SRIM were hospital practices, such as timely breastfeeding (BF) initiation, avoiding in-hospital commercial milk formula supplementation, and BF counselling/support. By contrast, maternal overweight/obesity, caesarean section, and poor maternal physical and mental health were risk factors for DOL and SRIM. SRIM was associated with primiparity, the mother's interpretation of the baby's fussiness or crying, and low maternal BF self-efficacy. Biomedical factors including epidural anaesthesia and prolonged stage II labour were associated with DOL. Thus, to protect against SRIM and DOL it is key to prevent unnecessary caesarean sections, implement the Baby-Friendly Ten Steps at maternity facilities, and provide BF counselling that includes baby behaviours.

Communities and employers show a high level of preparedness in supporting working mothers to combine breastfeeding with work in rural Kenya

Community Readiness Model (CRM) through pragmatic mixed methods design, combining quantitative CRM survey with qualitative data, was used to assess the level of preparedness and readiness among local leaders, employers and community members in supporting working mothers to combine breastfeeding with work. The study was conducted in one of the tea state farms in Kericho County of Kenya. A total of 17 purposively selected men (fathers), lactating mothers, peer educators, health professionals (doctors, nurses and nutritionists), tea plantation managers and grandmothers were interviewed. The CRM that has six different dimensions was applied to determine the stage of readiness to support working mothers to combine breastfeeding with work. Community Readiness Score (CRS) was calculated descriptively as mean ± standard deviation (SD). Thematic analysis using NVIVO software was used to analyse qualitative data. We found that the mean (±SD) CRS was 7.3 (1.9), which corresponded to the third highest level of the nine stages or the ‘stabilization’ stage of community readiness. Dimensionally, the mean CRS was the highest (8.3 ± 1.9) for leadership followed by community efforts (7.5 ± 2.1), whereas the lowest CRS was observed for knowledge of efforts (6.6 ± 2.3) and availability of resources (6.6 ± 1.9). In conclusion, high level of readiness to support working women to combine work with breastfeeding with suboptimal knowledge of efforts and availability of resources was observed in the area. Future interventions should focus on enabling the community to feel more comfortable and creating detailed and refined knowledge on combining breastfeeding with work.

NAM-help or burden? Intercultural evaluation of parental stress caused by nasoalveolar molding: a retrospective multi-center study

Objectives

Nasoalveolar molding (NAM) was developed to facilitate easier treatment and better outcomes for cleft lip and palate (CLP) patients. The aim of this study was to investigate the parental burden and possible intercultural differences of this treatment modality, which is often argued to burden parents to an extraordinary amount.

Materials and methods

Standardized questionnaires (available in English, Mandarin, and German) with 15 non-specific and 14 NAM-specific items to be retrospectively answered by Likert scales by parents of unilateral CLP patients with completed NAM treatment.

Results

The parents of 117 patients from two treatment centers in Taiwan and Germany were included. A very high level of overall satisfaction was found in both countries with significant intercultural differences in prenatal parent information, feeding problems, dealing with 3rd party’s perception, and experienced personal effort.

Conclusion

NAM is an effective treatment tool for children’s CLP deformities and their caregivers in overcoming the feeling of helplessness. Intercultural differences may be due to infrastructural reasons, cultural attitudes and habits, or different public medical education.

Clinical relevance

In addition to facilitating easier surgical treatment, NAM can be seen as a powerful coping strategy for parents dealing with a CLP deformity of their child and does not seem to burden them extraordinarily.

The double burden of overnutrition and undernutrition in mother-child dyads in Kenya: demographic and health survey data, 2014

The double burden of overnutrition and undernutrition is rapidly becoming a public health concern in low- and middle-income countries. We explored the occurrence of mother-child pairs of over- and undernutrition and the contributing factors using the 2014 Kenya Demographic and Health Survey data. A weighted sample of 7830 mother-child pairs was analysed. The children's nutritional status was determined using the WHO 2006 reference standards while maternal nutritional status was determined with BMI. Descriptive statistics, bivariate and multivariate logistic regression analysis were conducted. The proportion of overweight and obese mothers was 26 % (18·8 % overweight and 7·2 % obese). The prevalence of child stunting, underweight and wasting was 26·3, 12·8 and 5·1 %, respectively. Out of the overweight/obese mothers (weighted n 2034), 20 % had stunted children, 5·4 % underweight children and 3·1 % wasted children. Overweight/obese mother-stunted child pairs and overweight/obese mother-underweight child pairs were less likely to occur in the rural areas (adjusted OR (aOR) = 0·43; P < 0·01) in comparison with those residing in the urban areas (aOR = 0·54; P = 0·01). Children aged more than 6 months were more likely to be in the double burden dyads compared with children below 6 months of age (P < 0·01). The double burden mother-child dyads were more likely to be observed in wealthier households. Mother-child double burden is a notable public health problem in Kenya. Household wealth and urban residence are determinants of the double burden. There is need for target-specific interventions to simultaneously address child undernutrition and maternal overweight/obesity.

Infant feeding practices and determinant variables for early complementary feeding in the first 8 months of life: results from the Brazilian MAL-ED cohort site

OBJECTIVE

The present study aimed to describe breast-feeding, complementary feeding and determining factors for early complementary feeding from birth to 8 months of age in a typical Brazilian low-income urban community.

DESIGN

A birth cohort was conducted (n 233), with data collection twice weekly, allowing close observation of breast-feeding, complementary feeding introduction and description of the WHO core indicators on infant and young child feeding. Infant feeding practices were related to socio-economic status (SES), assessed by Water/sanitation, wealth measured by a set of eight Assets, Maternal education and monthly household Income (WAMI index). Two logistic regression models were constructed to evaluate risk factors associated with early complementary feeding.

RESULTS

Based on twice weekly follow-up, 65 % of the children received exclusive breast-feeding in the first month of life and 5 % in the sixth month. Complementary feeding was offered in the first month: 29 % of the children received water, 15 % infant formulas, 13 % other milks and 9·4 % grain-derived foods. At 6 months, dietary diversity and minimum acceptable diet were both 47 % and these increased to 69 % at 8 months. No breast-feeding within the first hour of birth was a risk factor for the early introduction of water (adjusted OR=4·68; 95 % CI 1·33, 16·47) and low WAMI index a risk factor for the early introduction of other milks (adjusted OR=0·00; 95 % CI 0·00, 0·02).

CONCLUSIONS

Data suggest local policies should promote: (i) early breast-feeding initiation; (ii) SES, considering maternal education, income and household conditions; (iii) timely introduction of complementary feeding; and (iv) dietary diversity.

Variation in the association between socioeconomic status and breastfeeding practices by immigration status in Taiwan: a population based birth cohort study

BACKGROUND

The relationship between socioeconomic status (SES) and breastfeeding has been extensively discussed in the literature. However, there is some evidence that this relationship can differ with immigration status. To date the majority of research investigating the relationships among SES, breastfeeding and immigration status has been conducted in Europe and the United States with a lack of similar research from Asia. Therefore, the aim of this study was to describe differences in breastfeeding practices between native-born Taiwanese mothers and immigrant mothers in Taiwan and to investigate any differences in the relationship between SES and breastfeeding practices by immigration status.

METHODS

Data analyzed came from the Taiwan Birth Cohort Study, the first longitudinal study of babies in Taiwan with a nationally representative sample born in 2005. In the present study, we included 21,217 mothers or primary caregivers who completed interview surveys when their child was 6 months old. Socioeconomic status was measured by the education level of mothers and fathers, and the couple's monthly income. Data analysis involved multiple logistic regression. Control variables included residential area, mother's employment status, age of the father and mother, and sex of the infant.

RESULTS

The proportion of immigrant mothers predominantly breastfeeding for 4 and for 6 months (Mainland Chinese mothers: 18.25 %, 36.29 %; Southeast Asian mothers: 10.71 %, 24.85 %) was significantly higher than that observed in their Taiwan-born counterparts (7.03 %, 16.22 %). Analysis stratified by immigration status showed that a higher level of parental education was associated with a greater likelihood of predominantly breastfeeding in Taiwanese mothers. However, no statistically significant relationship was observed between education and predominantly breastfeeding in immigrant mothers. Higher monthly income was also significantly associated with a greater likelihood of predominantly breastfeeding in Taiwanese mothers. However, there was no significant linear relationship between monthly income and predominantly breastfeeding in immigrant women.

CONCLUSION

The relationship between SES and breastfeeding is different in immigrant mothers and native-born Taiwanese mothers. Taiwanese policy should continue to encourage breastfeeding in immigrant mothers. However, greater attention should be placed on Taiwanese mothers from a low SES background.

Quality of life of mothers at the sixth week and sixth month post partum and type of infant feeding

INTRODUCTION

there is little scientific evidence on the relationship between maternal quality of life and type of infant feeding. The purpose of this study was to determine if there were differences in mother's quality of life by type of infant feeding.

MATERIAL AND METHODS

longitudinal prospective study with 364 women who gave birth at a public hospital at Madrid, Spain, between February and October 2013. To be included, the participants had to be a healthy primigravida aged 18-45 years who gave birth to a healthy newborn with a gestational age between 36 and 42 completed weeks, regardless of birth type. The hospital interviews were performed between 36 and 48 hours post partum in women who had case of vaginal/instrumental births and 60-72 hours post partum for women who had a caesarean birth. Telephone interviews were conducted at the sixth week and sixth month post partum, and included the SF-36 to measure quality of life. SF-36 scores were compared between breast feeding and artificial milk feeding. We also analysed the longitudinal change in SF-36 scores in both groups.

RESULTS

at the sixth week post partum, regardless of the infant feeding modality, an increased mental health score was recorded for mothers who reported that their children ate and slept well and for those who did not go to the emergency hospital service because of concern over their baby's health. No significant differences in quality of life were found between the two groups at six months post partum. Between the sixth week and sixth month post partum, quality of life improved significantly in both groups.

DISCUSSION

at the sixth week post partum, the proportion of children who ate and slept well and did not have to attend in an emergency hospital service was higher in the breast feeding group. This observation was associated with greater maternal quality of life. This positive indirect relationship between breast feeding and quality of life should be considered an additional maternal health benefit in the short term.

Benefits of a Dedicated Breastfeeding Facility and Support Program for Exclusive Breastfeeding among Workers in Indonesia

PURPOSE

A mother's working environment is believed to be a major determinant of exclusive breastfeeding (EBF) practice. We aimed to define the influence of a facility dedicated to breastfeeding and a breastfeeding support program at the workplace on breastfeeding practice.

METHODS

A cross-sectional study was performed in five workplaces. The inclusion criteria were female workers whose last child was between 6 and 36 months old. Observational data were obtained and a questionnaire was filled out. The World Health Organization definition for EBF was used.

RESULTS

Data from 186 subjects (74 office workers and 112 factory workers) were collected. Just over half (52%) of the mothers were between 20 and 46 years old, 75.3% had graduated from high school and university, 12.9% had more than two children and 36.0% owned a house. The prevalence of EBF during the last 6 months was 32.3%. A proper dedicated breastfeeding facility was available for 21.5% of the mothers, but only 7.5% had been in contact with a breastfeeding support program. The presence of a dedicated breastfeeding facility increased EBF practice almost threefold, by an odds ratio (OR) of 2.74 and a 95% confidence interval (CI) of 1.34-5.64 (p<0.05). Knowledge of the breastfeeding support program increased EBF practice by almost six times (OR, 5.93; 95% CI, 1.78-19.79) (p<0.05).

CONCLUSION

Our findings suggest that Governments should make it obligatory for employers to offer a breastfeeding support program and a dedicated breastfeeding facility at the workplace as these simple measures significantly increase EBF.

Multilevel analysis of air pollution and early childhood neurobehavioral development

To investigate the association between the ambient air pollution levels during the prenatal and postnatal stages and early childhood neurobehavioral development, our study recruited 533 mother-infant pairs from 11 towns in Taiwan. All study subjects were asked to complete childhood neurobehavioral development scales and questionnaires at 6 and 18 months. Air pollution, including particulate matter ≤10 μm (PM10), carbon monoxide (CO), sulfur dioxide (SO2), nitrogen dioxide (NO2), ozone (O3), and hydrocarbons, was measured at air quality monitoring stations in the towns where the subjects lived. Multilevel analyses were applied to assess the association between air pollution and childhood neurobehavioral development during pregnancy and when the children were 0 to 6 months, 7 to 12 months, and 13 to 18 months old. At 18 months, poor subclinical neurodevelopment in early childhood is associated with the average SO2 exposure of prenatal, during all trimesters of pregnancy and at postnatal ages up to 12 months (first trimester β = -0.083, se = 0.030; second and third trimester β = -0.114, se = 0.045; from birth to 12 months of age β = -0.091, se = 0.034). Furthermore, adverse gross motor below average scores at six months of age were associated with increased average non-methane hydrocarbon, (NMHC) levels during the second and third trimesters (β = -8.742, se = 3.512). Low-level SO2 exposure prenatally and up to twelve months postnatal could cause adverse neurobehavioral effects at 18 months of age. Maternal NMHC exposure during the 2nd and 3rd trimesters of pregnancy would be also associated with poor gross motor development in their children at 6 months of age.

Influence of partner support on an employed mother's intention to breastfeed after returning to work

BACKGROUND

Despite the increasing number of large companies complying with the demands for a breastfeeding-friendly workplace, providing on-site lactation support, some mothers still find continuing to breastfeed a challenge. We postulated that greater support and encouragement from the partner would be independently predictive of whether the mother would take advantage of workplace milk expression breaks and lactation rooms and continue to breastfeed after returning to work. To evaluate this hypothesis, we conducted a survey at a female labor-intensive electronics manufacturer in Taiwan.

SUBJECTS AND METHODS

Six hundred eight working mothers in an electronics manufacturing plant in Tainan Science Park in Southern Taiwan who had access to dedicated lactation rooms at the workplace were interviewed. Questionnaire content included female employee demographics, employment characteristics, partner-related characteristics, and breastfeeding behavior after returning to work following the birth of their most recently born child.

RESULTS

The partner's initial support of the choice to breastfeed and encouragement to use the lactation room and milk expression breaks and the mother's perception of the partner's support for baby care were significant predictors of the intention to continue to breastfeed after returning to work, after adjusting for the employed mother's demographics and employment characteristics, supporting our hypothesis.

CONCLUSIONS

These findings suggest that antenatal education or activities provided by the workplace should include the partner, which may improve workplace breastfeeding rates.

Employee perception of breastfeeding-friendly support and benefits of breastfeeding as a predictor of intention to use breast-pumping breaks after returning to work among employed mothers

BACKGROUND

Although increasing numbers of large companies are complying with demands for a breastfeeding-friendly workplace by providing lactation rooms and breast-pumping breaks, the effectiveness for intention to use breast-pumping breaks to express breast milk among employed mothers is uncertain. To explore the impact of employees' perceived breastfeeding support from the workplace and the benefits of breastfeeding on a woman's intention to use breast-pumping breaks after returning to work, we conducted a survey at a female labor-intensive electronics manufacturer in Taiwan.

SUBJECTS AND METHODS

A structured questionnaire survey was administered to 715 working mothers employed in an electronics manufacturing plant in Tainan Science Park in Southern Taiwan. Questionnaire content included female employee demographics, employment characteristics, and breastfeeding behavior after returning to work, as well as employees' perception of breastfeeding-friendly support and awareness of the benefits of breastfeeding when raising their most recently born child.

RESULTS

Higher education (odds ratio [OR] 2.33), non-clean room worksite (OR 1.51), awareness of breast-pumping breaks (OR 4.70), encouragement by colleagues to use breast-pumping breaks (OR 1.76), and greater awareness of the benefits of breastfeeding (OR 1.08) were significant predictors of the use of breast-pumping breaks after returning to work, whereas the perception of inefficiency when using breast-pumping breaks reduced an employed mother's intention to use breast-pumping breaks (OR 0.55).

CONCLUSIONS

This study finds an association between an appreciation of the benefits provided by the employer and the likelihood of increased usage of breastfeeding breaks. Workplaces and employers can help employed mothers to understand the benefits of breastfeeding, which may increase the intention of the mother to take breast-pumping breaks after returning to work.

Impact of a breastfeeding-friendly workplace on an employed mother's intention to continue breastfeeding after returning to work

BACKGROUND

Ever-increasing populations of women in their childbearing years are choosing to become employed. Breastfeeding provides unique health advantages to both the infant and mother. A breastfeeding-friendly workplace might be an important factor for predicting breastfeeding rates among working women. To explore the impact of breastfeeding-friendly support on the intention of working mothers to continue breastfeeding, we conducted a survey at a female labor-intensive electronics manufacturer in Taiwan.

SUBJECTS AND METHODS

A structured questionnaire survey was administered to 715 working mothers employed in an electronics manufacturing plant in Tainan Science Park in Southern Taiwan. Questionnaire content included female employee demographics, employment characteristics, continued breastfeeding behavior after returning to work, access to lactation rooms, and employee perception of the breastfeeding policy and support when raising their most recently born child.

RESULTS

A higher education level (odds ratio [OR]=2.66), lower work load (8 work hours/day) (OR=2.66), lactation room with dedicated space (OR=2.38), use of breast pumping breaks (OR=61.6), and encouragement from colleagues (OR=2.78) and supervisors (OR=2.44) to use breast pumping breaks were significant predictors of continued breastfeeding for more than 6 months after returning to work.

CONCLUSIONS

The findings of the present study suggest that to encourage and increase the rate of continued breastfeeding, workplaces should establish dedicated breastfeeding rooms and maintain a comfortable and clean environment. Furthermore, employers should provide encouragement and support for working mothers to continue breastfeeding after returning to work.

Fatores de risco associados ao desmame em crianças até seis meses de idade no município de São Paulo

OBJETIVO: Avaliar os fatores de risco associados à ausência de aleitamento materno exclusivo (AME) em crianças <6 meses de vida na cidade de São Paulo, em 2008. MÉTODOS: Aplicou-se o questionário do Projeto Amamentação e Municípios-1998 (AMAMUNIC) a pais/responsáveis de crianças <6 meses de idade durante a Campanha Nacional de Vacinação contra Poliomielite. Cálculo da amostra por conglomerados com sorteio em dois estágios. Os fatores analisados foram idade e educação materna, peso de nascimento, sexo, tipo de parto, nascer em Hospital Amigo da Criança, presença de aleitamento materno precoce, uso de chupeta nas últimas 24 horas e mãe trabalhando fora de casa. Análise estatística por regressão logística binária com SPSS, versão 15.0, sendo significante p<0,05. RESULTADOS: Foram realizadas 724 entrevistas, das quais 275 referiram (39,1%) aleitamento materno exclusivo (Grupo I - GI) e 429 (60,9%) sem aleitamento materno exclusivo (Grupo II - GII). Houve diferenças entre os grupos quanto ao uso da chupeta nas últimas 24 horas (GI 32,3 versus GII 59,8%; p<0.001), mães trabalhando fora (GI 12,4 versus GII 24,8%; p<0.001) e idade da criança (GI 74,1±45,3 versus GII 105,8±49,5 dias; p<0,0001).Na análise multivariada, houve associação entre ausência de aleitamento materno exclusivo e uso de chupeta (OR 3,02; IC95% 2,10-4,36), mãe trabalhando fora (OR 2,11; IC95% 1,24-3,57) e idade da criança (OR 1,01; IC95% 1,01-1,02). CONCLUSÕES: O uso da chupeta nas últimas 24 horas associou-se à ausência de AME em crianças menores do que seis meses, seguido pelo trabalho materno fora de casa e pela idade da criança, que são importantes fatores a serem controlados em programas de promoção do aleitamento materno.

Maternity Leave in Taiwan

Using the first nationally representative birth cohort study in Taiwan, this paper examines the role that maternity leave policy in Taiwan plays in the timing of mothers returning to work after giving birth, as well as the extent to which this timing is linked to the amount of time mothers spend with their children and their use of breast milk versus formula. We found that the time when mothers returned to work coincided with the duration of guaranteed leave. In particular, mothers with a labor pension plan resumed work significantly earlier than mothers with no pension plan, and mothers with no pension plan returned to work significantly later than those with pension plans. The short leave of absence guaranteed under existing policies translated into mothers spending less time with their children and being more likely to exclusively use formula by 6 months after birth. In contrast, mothers who resumed work later than 6 months after birth were more likely to have not worked before birth or to have quit their jobs during pregnancy. Implications and recommendations for parental leave policy in Taiwan are discussed.

Is infant feeding pattern associated with father's quality of life?

The aim of this study was to compare the health-related quality of life of fathers under different infant feeding type scenarios. The Medical Outcomes Study 36-item Short-Form was used to measure the health-related quality of life of 1,699 fathers, and the scores were used to look for associations with different infant feeding methods. Multivariable linear regression analysis was used to explore the contribution of the other potential related factors on fathers' quality of life. After controlling for confounding factors, fathers whose infants were ever being breast-fed reported lower scores than fathers whose infants were bottle-fed. Except for the infant feeding pattern, having a job, higher family income, and being the major caregiver were positively related to the father's quality of life. Fathers may not benefit during breast-feeding process. Because fathers' involvement plays an important role in the success of breast-feeding, the development of interventions that enable fathers to support their breast-feeding partner is very important.

Emerging Trends in Breastfeeding Practices in Singaporean Chinese Women: Findings from a Population-based Study

Introduction: This study records the prevalence and patterns of breastfeeding in Singaporean Chinese mothers who gave birth between 2000 and 2008. Materials and Methods: The Strabismus, Amblyopia and Refractive Error in Singaporean Children (STARS) study is a population-based survey conducted in South-Western Singapore. Disproportionate random sampling by 6-month age groups of Chinese children born from 2000 to 2008 was performed. The mothers (n = 3009) completed a standard questionnaire which recorded the initiation, content, method and duration of breastfeeding. World Health Organization (WHO) definitions for feeding content were used: Replacement (exclusive commercial formula or any liquid or solid/semi-solid food, excluding breast milk), Complementary (breast milk, solid/semi-solid foods, and any non-human liquid), and Exclusive (breast milk only, without additional food, drink or water). STARS-specific definitions for feeding method were used: Expressed (breast milk only fed via bottle, with no additional food or non-human liquid), Combination (breast milk and non-breast milk, fed via bottle and breast), and Direct (breast milk only fed via breast). Results: Breastfeeding initiation (overall prevalence 77.0%) and duration increased over time, and were independently associated with higher maternal education: in 2000 and 2001, 68.6% of mothers initiated breastfeeding and 12.9% breast fed for ≤6 months, versus 82.0% and 26.7%, respectively, from 2006 to 2008; 47.4% of primary-school-educated women initiated breastfeeding, and 11.1% fed for ≥6 months, vs 90.9% and 35.3%, respectively, of university-educated women (P <0.001). Expressed, Com bination and Complementary feeding also increased, while Replacement feeding decreased (P<0.001). There was no difference in breastfeeding patterns by the child’s gender. Conclusions: In a population-based sample of Singaporean Chinese mothers giving birth from 2000 to 2008, breastfeeding initiation and duration increased over time and were independently associated with higher maternal education. This increase was associated with increased milk expression and complementary feeding. Thus awareness of breastfeeding benefits is rising in Singapore, but future health policies may need to target less-educated mothers. Key words: Complementary content, Education, Expression, Maternal-child health

Maternal return to work and breastfeeding: a population-based cohort study

BACKGROUND

In recent decades there has been a marked rise in the participation of women with infants in the labour market, while there has been a decline in the prevalence rate of breastfeeding.

OBJECTIVE

To explore the relationship between maternal return to work and breastfeeding.

DESIGN

An on-going prospective longitudinal study.

SETTING AND PARTICIPANTS

Multistage stratified systematic sampling was designed to recruit 24,200 pairs, postpartum women and newborns, from the Taiwan national birth register in 2005. Participating women underwent two home interviews at 6 and 18 months after giving birth, following structured questionnaires. A total of 21,248 and 20,172 women were interviewed, and the completed interview rate was thus 87.8% and 83.4% at 6 and 18 months, respectively. All study participants provided informed consent as approved by the Ethics Review Board of the National Taiwan College of Public Health.

RESULTS

The overall prevalence of initial breastfeeding was 83.7%. Postpartum women returning to work less than or equal to 1 month had the lowest initiation of breastfeeding rate (77.5%), but had a higher prevalence of breastfeeding duration less than or equal to 1 month (34.9%) than the overall population (26.8%). Overall 67.9%, 39.4%, 25.4%, and 12.7% mothers who started breastfeeding still breastfed their infants at the age of 1, 3, 6 and 12 months, respectively. Women with maternal leave of less than or equal to 6 months ceased breastfeeding earlier than those with maternal leave beyond 6 months and those who did not return to work up to 18 months after birth. After adjustment for potential confounders, odds ratios of initial breastfeeding seemed no different, except those for postpartum women who returned to work less than or equal to 1 month and those who did not return to work. Mothers returning to work within 1 year after giving birth were significantly earlier in weaning than those without return to work.

CONCLUSION

In our study, an early maternal return to work, especial within 6 months after giving birth, was a barrier to the initiation and continuation of breastfeeding. Thus, a comprehensive strategy is required to encourage the practice of breastfeeding in working women from pregnancy to the return to work, and nurses should work to promote breastfeeding in the different occasion.

Predicting risk for early infantile atopic dermatitis by hereditary and environmental factors

BACKGROUND

Hereditary and environmental factors contribute to the occurrence of atopic dermatitis (AD). However, the interaction of these two factors is not totally understood.

OBJECTIVES

To evaluate the early risk factors for infantile AD at the age of 6 months and to develop a predictive model for the development of AD.

METHODS

In 2005, a representative sample of mother and newborn pairs was obtained by multistage, stratified systematic sampling from the Taiwan national birth register. Information on hereditary and environmental risk factors was collected by home interview when babies were 6 months old. Multivariate regression analysis was applied to determine the risk factors for AD in the infants.

RESULTS

A total of 20 687 pairs completed the study satisfactorily. AD was diagnosed in 7.0% of 6-month-old infants by physicians. Parental asthma, atopic dermatitis and allergic rhinitis, and maternal education levels were risk factors for AD in infants. Among environmental factors, fungus on walls at home and renovation/painting in the house during pregnancy were significantly associated with early infantile AD. Using these factors, the probability of having infantile AD was estimated and grouped into low, high and very high. With five runs of tests in mutually exclusive subsets of this population, the likelihood of AD for 6-month-old infants was consistent in all the groups with the predictive model. The highest predicted probability of AD was 70.1%, among boys with maternal education levels > 12 years, both parents with AD, renovation and painting of the house during pregnancy and fungus on walls at home. The lowest probability was 3.1%, among girls with none of the above factors.

CONCLUSIONS

This investigation provides a technique for predicting the risk of infantile AD based on hereditary and environmental factors, which could be used for developing a preventive strategy against AD, especially among those children with a family history of atopy.

The association between infant feeding pattern and mother’s quality of life in Taiwan

BACKGROUND

This study compared the health-related quality of life (HRQOL) of mothers using different infant feeding methods.

METHODS

We used the Medical Outcomes Study 36-item Short-Form (SF-36) to measure the HRQOL of 1,747 mothers and used the scores to look for associations with infant feeding methods (not breastfeeding, breastfeeding for <1 month, breastfeeding 1-5 months, and still breastfeeding at the 6th month). The mothers were chosen via a stratified sampling from the Taiwan national birth registration data between November and December 2003.

RESULTS

HRQOL and breastfeeding duration were positively associated. Of the eight unadjusted domain scores of the SF-36, general health perception and mental health were significantly different among these four different infant feeding groups (P < 0.05). After controlling for potential confounding factors, mothers who breastfed for 6 months or longer had a higher HRQOL score than the other mothers. In addition, their physical functioning, general health perception and mental health scores were higher than those of mothers who did not breastfeed (P < 0.05). Mother's family income and parity and child's health status were also associated with mother's quality of life.

CONCLUSIONS

Compared to the other mothers, mothers who breastfed for six moths or longer had better HRQOL. However, the limitation that this study was cross-sectional in design should be considered and further studies are needed.
