Family correlates of daughter's and son's locus of control expectancies during childhood

Children who expect they can bring about good outcomes and avoid bad outcomes tend to experience more personal successes. Little is known about factors that contribute to these ‘control expectancies’. The purpose of the present study was to determine whether children's internal control expectancies occur in the context of parents’ internal control expectancies, low family strain, and high family cohesiveness and whether these factors are more strongly related to daughters’ than sons’ control expectancies. A community sample of 85 children aged 9–11 years and their parents (85 mothers; 63 fathers) completed rating scales. Fathers’ more internal control expectancies and mothers’ reports of fewer family strains were associated with daughters’ but not sons’ greater internal control expectancies, and greater family cohesiveness was related to both daughters’ and sons’ internal control orientations. These findings suggest that family factors may contribute to children's, particularly daughters’, development of internal control expectancies.     

Mother and father involvement in day care centers serving infants and young toddlers

This study compared the involvement of 28 mothers and their spouses in day care centers serving infants and toddlers. The sample consisted of parents who work at varying distances from the center. Parents were interviewed ten times each to determine the amount of time they spend in the center, frequency of communication with care providers, mid-day visits to the center, playing with the child, and holding the child in the center. Factor analysis reduced these variables to one parental involvement factor. Mothers were significantly more involved than fathers in the center, after statistically controlling for distance to the workplace and occupational status.

Parental Traits Associated with Adherence to the Mediterranean Diet in Children and Adolescents in Croatia: A Cross-Sectional Study

The Mediterranean diet (MD) is known to be one of the healthiest dietary patterns. Despite the significance of a healthful diet during the early stage of life, data for young individuals indicate that nutrition problems are common. This cross-sectional study aimed to determine parental factors associated with MD adherence in children and adolescents living in the Mediterranean region in Croatia. In total, 2623 children aged 2 to 18 years and their parents participated in this study. Data were collected during the period from September 2021 to February 2022 by using an anonymous questionnaire. We used KIDMED and MEDAS questionnaires for assessing MD adherence in young individuals and their parents, respectively. To assess the association of children’s MD adherence categories with the parental predictors, we performed multivariate multinomial logistic regression. Results showed that the children of parents with a low MD adherence are much more likely to have poor MD adherence than good (OR = 47.54 (95% C.I 18.24, 123.87), p < 0.001) or average (OR = 5.64 (95% C.I 3.70, 8.6), p < 0.001) MD adherence. Further, children of fathers with higher BMI (OR = 1.035 (95% C.I 1.0, 1.071)) and those who do not live with both parents (OR = 1.703 (95% C.I 0.994, 2.916), p = 0.053) are more likely to have poor MD adherence than good MD adherence. These results indicate that interventions focusing on enhancing the quality of both parents’ diets could effectively improve their children’s eating habits.     

Time in Parenting Activities in Dual‐Earner Families at the Transition to Parenthood

Time parenting was compared for new mothers and fathers in a sample of 182 dual‐earner families. Parenting domains included positive engagement, responsibility, routine child care, and accessibility. Time diaries captured parents' time use over a 24‐hour workday and nonworkday when infants were age 3 and 9 months. Parents were highly involved with their infants. Mothers were more involved than fathers in positive engagement and routine child care on days and at each assessment, and allocated more available time on workdays to these domains than fathers, with one exception. Fathers and mothers allocated similar shares of available workday time to positive engagement at 9 months. Greater equity in responsibility and accessibility was found; mothers spent more, and a greater share of, parenting time in responsibility than fathers on the 9‐month workday only, and were more accessible on the 3‐month workday only. Implications for parents in today's diverse families are discussed.     

Paternal incarceration and trajectories of marijuana and other illegal drug use from adolescence into young adulthood: evidence from longitudinal panels of males and females in the United States

Aims One‐eighth of young adults in the United States report that their biological father has ever been incarcerated (FEI). This study is the first to examine associations between FEI and trajectories of substance use during the transition from adolescence into young adulthood for the US population. Design Using multi‐level modeling techniques, trajectories of marijuana and other illegal drug use are examined, with FEI as the primary independent variable. Setting Data are from the first three waves of the National Longitudinal Study of Adolescent Health, a nationally representative sample of US adolescents beginning in 1995. Participants Panels of 7157 males and 7997 females followed from adolescence (7th–12th grades) into early adulthood (ages 18–27 years). Measurements Dependent variables included an ordinal measure of marijuana frequency of use in last thirty days, and a dichotomous measure for whether respondent had any use in the last thirty days of illegal drugs such crystal meth, cocaine, heroin, hallucinogens, PCP, LSD, speed, and ecstasy. Findings Among males and females, respectively, FEI is associated with an increased frequency of marijuana use, and increased odds of any other illegal drug use. Interactions between FEI and age further reveal that FEI is associated with an accentuated trajectory (i.e. a steeper slope) of marijuana use, and an elevated risk (i.e. higher mean level) of other illegal drug use. Conclusions Analysis provides some of the first evidence that paternal incarceration is significantly associated with drug use among U.S. males and females, even after controlling for a number of family background, parental, and individual characteristics.     

The contribution of yogurt to nutrient intakes across the life course

Yogurt is a nutrient‐dense food within the milk and dairy products food group. The nutritional content of yogurt varies depending on the processing method and ingredients used. Like milk, it is a good source of protein and calcium, and can be a source of iodine, potassium, phosphorus and the B vitamins – riboflavin (B₂) and vitamin B₁₂ (depending on type). Some yogurt products are also fortified with vitamin D. The nutritional value of dairy products (milk, cheese and yogurt) and the importance of the nutrients they provide for bone health are well recognised. These foods are collected together as one of the four main food groups within the UK's eatwell plate model that illustrates a healthy, balanced diet. Studies exploring the nutritional and health attributes of yogurt are limited but some research has suggested benefits in relation to bone mineral content, weight management, type 2 diabetes and metabolic profile. Yogurt consumption has also been associated with diet quality. The aim of this paper is to use national survey data to examine yogurt consumption in the UK and consider its contribution to nutrient intakes at different life stages within the context of nutritional challenges in each age group. The contribution of yogurt to energy and nutrient intakes across the life course was calculated via secondary analysis of data from the Diet and Nutrition Survey of Infants and Young Children (2011) and the National Diet and Nutrition Survey (2008/2009–2010/2011). The products categorised within the ‘yogurt group’ included all yogurt, fromage frais and dairy desserts, and fortified products. Comparisons were also made between specific sub‐categories of yogurt, namely ‘yogurt’, ‘fromage frais’ and ‘dairy desserts’. Nutrients included in the analyses were energy; the macronutrients; micronutrients that yogurt can be defined as a ‘source of’; micronutrients that may be of concern in the UK population; and vitamin D for fortified products. A simple dietary modelling exercise was also undertaken to investigate the potential impact of including an additional pot of yogurt per day on the nutrient intakes of adolescents. Children aged 3 years and under had the highest intakes of yogurt [mean intake 43.8 g/day (SD 39.7 g) in 4–18 month‐olds; 46.7 g/day (SD 39.1 g) in 1.5–3 year‐olds], and adolescents (11–18 years) consumed the least [21 g/day (SD 38.0 g)]. In adults, highest mean consumption [35.7 g/day (SD 55.0 g)] was during middle age (50–64 years), equivalent to less than a third of a standard 125 g pot. Around 80% of young children (aged 3 years and under) but only a third of teenagers and young adults had consumed any yogurt product during the survey period of 4 days. Average yogurt consumption was twice as high in women as men among older adults (65 years and over), while gender differences in consumption were less apparent in children. Fromage frais and fortified yogurt products were most commonly consumed by younger children, as were dairy desserts in those aged 4–18 years. Among adults, yogurt per se was most commonly consumed. Children aged 4–10 years exhibited the most variety in the types of yogurt consumed. Low‐fat yogurt (including those with added fruit, nuts and cereals) was the most commonly consumed yogurt type when all ages were combined. More than a third of all yogurt products consumed by children aged 3 years and under were fortified, compared with 18% in those aged 4–10 years. During adulthood, the consumption of fortified products was negligible. The yogurt group made a useful contribution to micronutrient intakes in children aged 4 months to 10 years, particularly vitamin B₁₂ (4–18 months: 7.6%; 1.5–3 years: 5.3%; 4–10 years: 3.8%), riboflavin (7.8%, 6.9%, and 5.7%, respectively), calcium (9.5%, 8.2%, and 5.9%, respectively), iodine (7.2%, 7.6%, and 7%, respectively) and phosphorus (8.1%, 6.3%, and 4.3%, respectively). It also provided 3.9% of the total intake of vitamin D in those aged 4–18 months and 10.5% in those aged 1.5–3 years. Although the contribution to total dietary energy intake was low (4.9% at 4–18 months and 4.2% at 1.5–3 years), yogurt contributed a high proportion of non‐milk extrinsic sugars (NMES) to the diets of young children (22.7% and 11.1% in 4–18 months and 1.5–3 years, respectively). However, the total NMES intake was comparatively low in children aged 4–18 months (6.7% total energy), and 11.6% in 1.5–3 year‐olds (compared to 15.3% total energy in children aged 11–18 years in this survey). As children aged, the contribution of yogurt (all categories combined) to micronutrient intake, as well as to NMES, decreased, reflecting the increasing amounts and variety of foods in the diet. Yogurt made a small contribution to energy and macronutrient intakes during adulthood, with the greatest proportions mostly in the older age group (65 years and over) (energy: 1.7%; fat: 1.3%; saturated fatty acids: 2.1%; NMES: 4%). As intake was higher among women, yogurt made a greater contribution to their micronutrient intakes compared with men, providing >5% of the reference nutrient intakes (RNIs) for phosphorus, iodine, calcium, vitamin B₁₂ and riboflavin. Simple dietary modelling was carried out to investigate the hypothetical change in mean nutrient intakes among adolescents aged 11–14 and 15–18 years, if they were all to add an extra 125 g pot of low‐fat fruit yogurt to their current diet. This showed an increase in average intake, as a percentage of the RNI, for several micronutrients for which there is some evidence of low intakes in this age group, notably calcium in boys and girls (11–18 years) and iodine in girls (11–18 years). Although some benefits for micronutrient intakes were noted, such advice would impact on energy and macronutrient intakes (including NMES), and would need to be given in the context of the wider diet (e.g. as ‘swaps’ for less nutrient‐dense foods). In conclusion, yogurt makes a small but valuable contribution to nutrient intakes in the UK, particularly in young children. Among adolescents, the addition of a low‐fat yogurt would help meet recommended intakes for several micronutrients, particularly calcium and iodine, which are of concern in some teenage diets. Advice to replace some types of snacks and desserts, particularly those high in fat and sugars and low in micronutrients, with a pot of yogurt or similar dairy product may improve the nutrient density of their diet.
