Relations between child self-control, maternal relational frustration, and teacher-child conflict: a longitudinal study with children from dual-earner families.

This longitudinal study follows children from dual-earner families in 4 time-points, covering the early childhood period. We examined the influence of work-family conflict (WFC) on maternal relational frustration (RF) towards the child, and investigated the reciprocal relations among maternal RF, children's self-control (SC), and teacher-child (TC) conflict over time. Participants were 214 children (97 girls; M age = 4.00 years), their mothers, and teachers. Mothers reported their own WFC and RF, whereas teachers reported child SC and T-C conflict. Results from a cross-lagged panel model indicated the experience of WFC positively predicted maternal RF. Maternal RF and T-C conflict were negatively related to the child later SC abilities. Conversely, children who displayed SC difficulties were more likely to experience later maternal RF and T-C conflict. There was evidence supporting the bidirectional effects of child SC and T-C conflict across time. Moreover, maternal RF and T-C conflict were indirectly linked, via child SC. The findings are consistent with a transactional view of development, stressing the importance of contextual factors to the quality of caregiving relationships and highlighting the complex and reciprocal relations between child regulatory competence and the quality of relationships with distinct caregivers.

Association between parents' work hours and nutrient inadequacy in Japanese schoolchildren on weekdays and weekends.

OBJECTIVES: Evidence is sparse concerning whether the nutrient intake in schoolchildren differs according to parents' work hours. The aim of this study was to investigate the relationship between parents' work hours and nutrient inadequacy among Japanese primary schoolchildren using dietary reference intakes on days with and without a school lunch. METHODS: Participants included 10- to 11-y-old children in grade 5 from 19 public primary schools in four prefectures of east Japan. Data for 699 children were analyzed. Participants completed 24-h dietary records with photographs of their meals for 4 d consecutively, which included of 2 d of weekdays and 2 d of weekends. Their mothers' and fathers' work hours were obtained from questionnaires that were completed by the participants' guardians. Logistic regression analyses were used to estimate the odds ratios for whether participants had poor nutrient intake, with adjustment for confounders. RESULTS: Children whose mothers worked ≥40 h/wk had significantly higher rates of nutrient shortages for vitamins A, E, K, and B6, pantothenic acid, potassium, magnesium, and iron (P = 0.007, 0.003, 0.007, 0.023, 0.021, 0.045, 0.004, and 0.009, respectively) than those in the 0 h/wk group. These differences were not significant based on fathers' working hours, with the exception of vitamin A (≥40 versus 0-39 h/wk, P = 0.032). Additionally, nutrient shortages for children were more pronounced on weekdays than on weekends. CONCLUSIONS: This evidence revealed the necessity to improve nutrition intake in children whose mothers work more than statutory working hours, which would enable children to have adequate nutrient intake, especially on weekdays.

Mothers' Work Status and 17-month-olds' Productive Vocabulary.

Literature examining the effects of mothers' work status on infant language development is mixed, with little focus on varying work-schedules and early vocabulary. We use naturalistic data to analyze the productive vocabulary of 44 17-month-olds in relation to mothers' work status (Full-time, Part-time, Stay-at-home) at 6 and 18 months. Infants who experienced a combination of care from mothers and other caretakers had larger productive vocabularies than infants in solely full-time maternal or solely other-caretaker care. Our results draw from naturalistic data to suggest that this care combination may be particularly beneficial for early lexical development.

Maternal work and exclusive breastfeeding in Mansoura, Egypt.

BACKGROUND: Working mothers face unique barriers to breastfeeding, despite the compelling evidence of its benefits. The aim of this study was to describe exclusive breastfeeding (EBF) rate of working mothers and associated factors. METHODS: Cross-sectional study was carried out in Mansoura District, Egypt from 1 July to 31 December 2017 among working mothers attending health care facilities for vaccinating their infants aged 6 months. Data were collected using a questionnaire covering sociodemographic and occupational data; breastfeeding supportive workplace facilities; antenatal and natal care; infant's data; and EBF practice. RESULTS: EBF rate was 14.1%. Independent predictors were being still on work leave, return to work 4 months after childbirth, working as farmer/manual worker and in trades and business, and being self/family employed. CONCLUSIONS: EBF rate is low among working mothers. There is a need to extend maternity leave and provide promoting workplace facilities.

The Relation between Maternal Work Hours and Primary School Students' Affect in China: The Role of the Frequency of Mother-Child Communication (FMCC) and Maternal Education.

Background: Although substantial evidence suggests that maternal work hours may have a negative effect on children's cognitive development, the link between maternal work hours and children's affect remains unclear. Some studies have observed that non-daytime maternal work hours are associated with more emotional problems among children. However, few studies have focused on the effects of maternal work hours on workdays and non-workdays. Therefore, this study separately investigated the relation between maternal work hours on workdays and on non-workdays and explored the mediating role of the frequency of mother-child communication (FMCC) and the moderating role of maternal education. Method: Using cluster sampling, this study selected 879 students in grades 4-6 at two primary schools in the Hebei and Shandong provinces in China and their mothers as the study subjects. A multi-group structural equation model (SEM) was used to test the relations between maternal work hours, FMCC and children's affect and the moderating effect of maternal education. Results: (1) Non-college-educated mothers' work hours on workdays negatively predicted FMCC, but there was no such effect for college-educated mothers; (2) non-workday work hours of all employed mothers negatively predicted FMCC; (3) the FMCC of all employed mothers positively predicted children's positive affect; (4) the FMCC of college-educated mothers negatively predicted children's negative affect although there was no such relation for non-college-educated mothers; (5) there was a significant mediating effect of FMCC on the relation between maternal work hours and children's affect only for non-college-educated mothers; and (6) the workday work hours of non-college-educated mothers positively predicted children's negative affect, but this correlation was negative for college-educated mothers. Conclusion: Maternal work hours have a marginally significant negative effect on children's affect through FMCC only for non-college-educated mothers. Compared with non-college-educated mothers, college-educated mothers more easily compensate for the loss of communication opportunities caused by increased work hours on workdays, and children with college-educated mothers benefit more from this communication. However, compensating for the loss of communication opportunities caused by increased work hours on non-workdays is difficult for all employed mothers.

Non-linear relationship between maternal work hours and child body weight: Evidence from the Western Australian Pregnancy Cohort (Raine) Study.

Using longitudinal data from the Western Australia Pregnancy Cohort (Raine) Study and both random-effects and fixed-effects models, this study examined the connection between maternal work hours and child overweight or obesity. Following children in two-parent families from early childhood to early adolescence, multivariate analyses revealed a non-linear and developmentally dynamic relationship. Among preschool children (ages 2 to 5), we found lower likelihood of child overweight and obesity when mothers worked 24 h or less per week, compared to when mothers worked 35 or more hours. This effect was stronger in low-to-medium income families. For older children (ages 8 to 14), compared to working 35-40 h a week, working shorter hours (1-24, 25-34) or longer hours (41 or more) was both associated with increases in child overweight and obesity. These non-linear effects were more pronounced in low-to-medium income families, particularly when fathers also worked long hours.

ABSTRACT Objective: Identify, in scientific literature, the main factors associated with early weaning. Method: This study is a systematic review of the Lilacs and Medline databases. The focus is on complete articles in English, Spanish and Portuguese published between 2004 and 2013. The guiding question is: "What factors influence early weaning?" Results: In all, 1,481 articles were identified and 39 met the inclusion criteria. The main factors that influence early weaning included, among others, maternal labor (33.3%), use of pacifiers (30.8%), weak milk (17.9%), trauma and nipple pain (17.9%), Introduction of other types of milk (15.4%), and the mother's/father's education (15.4%). Conclusion: Several factors are related to early weaning, which exhibits a strong sociocultural and historical determination that can be evidenced by a comparison of breastfeeding patterns among different populations and in the course of time.

Changes in work behavior during pregnancy in rural Anhui, China from 2001-03 to 2009: a population based cross-sectional study.

BACKGROUND: In low- and middle-income countries, many women continue working later into pregnancy. In our recent study on some areas in rural China, most women stopped working already during the first trimester (≤3 months) of pregnancy. In this paper we aimed to explore whether stopping work during early pregnancy has changed over an 8 year period (between 2001-03 and 2009); we also studied whether the reasons for stopping work early were the same in the two time periods. METHODS: A population-based cross-sectional survey with a representative sample of new mothers was carried out in one rural county in Anhui Province in 2001-03 (N = 1479 respondents) and in two other rural counties in 2009 (N = 1574 respondents). Both surveys were used to evaluate prenatal care interventions not related to work behavior. The surveys targeted all women who had recently given birth. Multilevel logistic regression analysis was used to examine the determinants of work behavior in the two time periods. RESULTS: There was a big change in the working behavior between the two survey years: in the period 2001-03 6 % and in 2009, 53 % of pregnant women stopped working at ≤3 months (percentage change 839, 95 % CI -15.90 to 1694.49). In 2001-03, 30 % and in 2009, 23 % of pregnant women worked the same as before pregnancy (percentage change -22.30, 95 % CI -90.28 to 45.68). In both time periods women with two children were less likely to stop work at ≤3 months of pregnancy. Non-farmers were more likely in 2001-03 but less likely in 2009 to stop work at ≤3 months of pregnancy. Women with medium township-level income were more likely to maintain the same level of work as before pregnancy in 2001-03, while in 2009 women with high township-level income were less likely to work the same. CONCLUSION: Stopping work very early during pregnancy appeared to have become very common from 2001-3 to 2009 in rural Anhui, China and was not explained by women's background characteristics.

Maternal work and exclusive breastfeeding practice: a community based cross-sectional study in Efutu Municipal, Ghana.

BACKGROUND: Maternal work has been identified as one of the factors that affect exclusive breastfeeding in the first six months of life. In Ghana, mothers engaged in the formal sector of employment are unable to exclusively breastfeed after maternity leave because facilities at their work places and conditions of work do not support exclusive breastfeeding. Even though maternal work and exclusive breastfeeding does not seem well matched, not all maternal work are incompatible with the practice of exclusive breastfeeding. This study seeks to identify the features of maternal work associated with exclusive breastfeeding in Effutu Municipal in the Central Region of Ghana. To achieve the above aim, I discuss the different types of maternal work, their characteristics, and how the work may influence exclusive breastfeeding. METHODS: The study is a community based cross-sectional study involving 225 mother-infant pairs attending community based Child Welfare Clinics in Effutu Municipal, Ghana. Data were collected through face-to-face structured interviews and focus group discussions over a period of five months in 2015. Data on breastfeeding is based on the breastfeeding practice in the 24 h preceding the survey. Chi-square test is used to identify strength of association between the features of maternal work and exclusive breastfeeding practice. RESULTS: The exclusive breastfeeding rate among mothers with infants between the ages of 0 - 5 months is 72%. The mean and median number of breastfeeds per day is 11 ± 2.7 and 13.5 respectively. A significant difference in exclusive breastfeeding was established between mothers in the formal (16%) and informal (84%) sectors of employment (p = 0.020). The study also established a significant difference in breastfeeding frequency between mothers in the formal (9%) and informal (91%) sectors of employment (p = 0.001). There was also a significant difference in breastfeeding frequency among respondents that go to work with their infant (64%) and those who do not go to work with their infant (36%) (p = 0.000). CONCLUSION: Interventions to promote exclusive breastfeeding should include the use of existing family structures, supportive cultural beliefs, and practices and promotion of an infant-friendly work environment.

Feeding a child with mealtime challenges: A mother's work.

BACKGROUND: The literature suggests that at least 25% of all children and up to 80% of children with developmental disabilities have some type of feeding and/or eating difficulty. Currently there is limited information in the literature related to mothers who are mothering young children with difficulties in the area of feeding and eating. Specifically there is little information available regarding how mothering a young child with difficulties in feeding and eating impacts participation in the work of mothering. OBJECTIVE: This paper discusses a piece of the qualitative portion of a mixed methods study. The qualitative portion of the study sought to examine the lived experience of mothers who were mothering a young child with feeding concerns. PARTICIPANTS: Five women between the ages of 26 and 41 years of age agreed to participate in this portion of the study. All of the women were married and were mothering a child between 12 and 36 months experiencing concerns related to feeding. METHODS: Phenomenological methods were used to complete the qualitative portion of this study. Each woman participated in one interview in her own home that lasted between one and two hours. RESULTS: Five themes emerged from the data analysis, feeling supported, seeking support, the range of emotions/feelings, dealing with the system, and the complexity of feeding. Two of the themes are discussed in this paper in detail as they relate to maternal work. CONCLUSIONS: Data from this study were analyzed in relationship to maternal work. Findings highlight the difficulty of negotiating daily mealtime occupations and support the connection between mealtime occupations and maternal work as outlined by Ruddick.

Maternal work and children's diet, activity, and obesity.

Mothers' work hours are likely to affect their time allocation towards activities related to children's diet, activity and well-being. For example, mothers who work more may be more reliant on processed foods, foods prepared away from home and school meal programs for their children's meals. A greater number of work hours may also lead to more unsupervised time for children that may, in turn, allow for an increase in unhealthy behaviors among their children such as snacking and sedentary activities such as TV watching. Using data on a national cohort of children, we examine the relationship between mothers' average weekly work hours during their children's school years on children's dietary and activity behaviors, BMI and obesity in 5th and 8th grade. Our results are consistent with findings from the literature that maternal work hours are positively associated with children's BMI and obesity especially among children with higher socioeconomic status. Unlike previous papers, our detailed data on children's behaviors allow us to speak directly to affected behaviors that may contribute to the increased BMI. We show that children whose mothers work more consume more unhealthy foods (e.g. soda, fast food) and less healthy foods (e.g. fruits, vegetables, milk) and watch more television. Although they report being slightly more physically active, likely due to organized physical activities, the BMI and obesity results suggest that the deterioration in diet and increase in sedentary behaviors dominate.

Maternal work conditions and child development.

How do maternal work conditions, such as psychological stress and physical hazards, affect children's development? Combining data from the Child Development Supplement of the Panel Study of Income Dynamics and the Occupational Information Network allows us to shed some light on this question. We employ various techniques including OLS with extensive controls, a value added approach and individual fixed effects in order to address potential endogeneity problems. Our results reveal that mothers' exposure to work-related hazards negatively affects children's cognitive development and to work-related stress negatively affects children's behavioral development. While maternal time investments play a small but significant role in mediating these negative associations, paternal time investments neither reinforce nor compensate these associations.

The public health implications of maternal care trade-offs.

The socioeconomic and ethnic characteristics of parents are some of the most important correlates of adverse health outcomes in childhood. However, the relationships between ethnic, economic, and behavioral factors and the health outcomes responsible for this pervasive finding have not been specified in child health epidemiology. The general objective of this paper is to propose a theoretical approach to the study of maternal behaviors and child health in diverse ethnic and socioeconomic environments. The specific aims are: (a) to describe a causal pathway between the utility that women obtain through work outside the home and through child care and disease hazard rates in childhood using an optimization model; (b) to specify the influence of ethnic and socioeconomic factors on model constraints; (c) to use the model as a tool to learn about how different combinations of maternal wage labor and child care time might influence child health outcomes in diverse social contexts; (d) to identify parameters that will require measurement in future research; (e) to discuss research strategies that will enable us to obtain these measurements; and (f) to discuss the implications of the model for biostatistical modeling and public health intervention. Optimization models are powerful heuristic tools for understanding how ethnic, environmental, family, and personal characteristics can place important constraints on both the quality and quantity of care that women can provide to their children. They provide a quantitative appreciation for the difficult trade-offs that most women face between working in order to purchase basic goods that children cannot do without (e.g., food, clothing, shelter, health insurance), and increasing offspring well-being through child care (e.g., training in social skills, affection, protection from environmental hazards, help with homework).
