Parental control over feeding in infancy. Influence of infant weight, appetite and feeding method

Background and objective: Parental control over feeding has been linked to child overweight. Parental control behaviours have been assumed to be exogenous to the child, but emerging evidence suggests they are also child-responsive. This study tests the hypothesis that parental control in early infancy is responsive to infant appetite and weight. Subjects and methods: Participants were 1920 mothers from the Gemini twin cohort, using one randomly selected child per family. Data come from questionnaires completed when the children were approximately 8 months. Mothers completed measures of ‘pressure’ and ‘restriction’, reported feeding method (breast- and bottle feeding), rated their infant's appetite during the first 3 months, provided health professional recorded weight measurements, and reported their concerns about their infant's weight. Logistic regression examined predictors of ‘pressure’ and ‘restriction’, adjusting for maternal demographics and BMI. Interactions between feeding method and control were also tested. Results: ‘Pressure’ was associated with lower birth weight (OR = 0.79, 95% CI: 0.65–0.97), greater concern about underweight (OR = 1.88, 1.29–2.75), and lower infant appetite (OR = 0.59, 0.47–0.75). ‘Restriction’ was associated with higher appetite (OR = 1.44, 1.09–1.89) and bottle feeding (OR = 2.86, 2.18–3.75). A significant interaction with feeding method indicated that infants with high appetites were more likely to be restricted only if they were bottle-fed (OR = 1.52, 1.13–2.04). Conclusion: Mothers vary in their levels of control over milk-feeding and this is partly responsive to the infant's characteristics. They tend to pressure infants who are lighter and have a smaller appetite, and restrict infants with larger appetites if they are bottle-fed. Guidance on infant feeding may be better received if it acknowledges that parents respond to infant characteristics in order to achieve their feeding goals

Energy and nutrient intakes of young children in the UK:Findings from the Gemini twin cohort

Data on the diets of young children in the UK are limited, despite growing evidence of the importance of early diet for long-term health. We used the largest contemporary dietary data set to describe the intake of 21-month-old children in the UK. Parents of 2336 children aged 21 months from the UK Gemini twin cohort completed 3-d diet diaries in 2008/2009. Family background information was obtained from questionnaires completed 8 months after birth. Mean total daily intakes of energy, macronutrients (g and %E) and micronutrients from food and beverages, including and excluding supplements, were derived. Comparisons with UK dietary reference values (DRV) were made using t tests and general linear regression models, respectively. Daily energy intake (kJ), protein (g) and most micronutrients exceeded DRV, except for vitamin D and Fe, where 96 or 84 % and 70 or 6 % of children did not achieve the reference nutrient intake or lower reference nutrient intake (LRNI), respectively, even with supplementation. These findings reflect similar observations in the smaller sample of children aged 18–36 months in the National Diet and Nutrition Survey. At a population level, young children in the UK are exceeding recommended daily intakes of energy and protein, potentially increasing their risk of obesity. The majority of children are not meeting the LRNI for vitamin D, largely reflecting inadequate use of the supplements recommended at this age. Parents may need more guidance on how to achieve healthy energy and nutrient intakes for young children

Sleep and nighttime energy consumption in early childhood:A population-based cohort study

BACKGROUND: Shorter sleep is a risk factor for weight gain in young children. Experimental studies show that sleep deprivation is associated with higher nighttime energy intake, but no studies have examined the patterning of energy intake in relation to nighttime sleep duration in young children. OBJECTIVES: The objectives of the study were to test the hypothesis that shorter‐sleeping children would show higher nighttime energy intake and to examine whether the additional calories were from drinks, snacks or meals. METHODS: Participants were 1278 families from the Gemini twin cohort, using data from one child per family selected at random to avoid clustering effects. Nighttime sleep duration was measured at 16 months of age using the Brief Infant Sleep Questionnaire. Energy intake by time of day and eating episode (meal, snack, drink) were derived from 3‐day diet diaries completed when children were 21 months. RESULTS: Consistent with our hypothesis, shorter‐sleeping children consumed more calories at night only (linear trend P < 0.001), with those sleeping <10 h consuming on average 120 calories (15.2% of daily intake) more at night than those sleeping ≥13 h. The majority of nighttime intake was from milk drinks. Associations remained after adjusting for age, sex, birth weight, gestational age, maternal education, weight and daytime sleep. CONCLUSIONS: Shorter‐sleeping, young children consume more calories, predominantly at night, and from milk drinks. Parents should be aware that providing milk drinks at night may contribute to excess intake. This provides a clear target for intervention that may help address associations between sleep and weight observed in later childhood

Progression of coronary artery calcification in conventional hemodialysis, nocturnal hemodialysis, and kidney transplantation

Introduction Cardiovascular disease is the leading cause of death in end-stage renal disease (ESRD) and is strongly associated with vascular calcification. An important driver of vascular calcification is high phosphate levels, but these become lower when patients initiate nocturnal hemodialysis or receive a kidney transplant. However, it is unknown whether nocturnal hemodialysis or kidney transplantation mitigate vascular calcification. Therefore, we compared progression of coronary artery calcification (CAC) between patients treated with conventional hemodialysis, nocturnal hemodialysis, and kidney transplant recipients. Methods We measured CAC annually up to 3 years in 114 patients with ESRD that were transplantation candidates: 32 that continued conventional hemodialysis, 34 that initiated nocturnal hemodialysis (>= 4x 8 hours/week), and 48 that received a kidney transplant. We compared CAC progression between groups as the difference in square root transformed volume scores per year (Delta CAC SQRV) using linear mixed models. Reference category was conventional hemodialysis. Results The mean age of the study population was 53 +/- 13 years, 75 (66%) were male, and median dialysis duration was 28 (IQR 12-56) months. Median CAC score at enrollment was 171 (IQR 10-647), which did not differ significantly between treatment groups (P = 0.83). Compared to conventional hemodialysis, CAC progression was non-significantly different in nocturnal hemodialysis -0.10 (95% CI -0.77 to 0.57) and kidney transplantation -0.33 (95% CI -0.96 to 0.29) in adjusted models. Conclusions Nocturnal hemodialysis and kidney transplantation are not associated with significantly less CAC progression compared to conventional hemodialysis during up to 3 years follow-up. Further studies are needed to confirm these findings, to determine which type of calcification is measured with CAC in end-stage renal disease, and whether that reflects cardiovascular risk

Gebitstoestand en mondgezondheid van basisschoolkinderen

De laatste decennia is er veel aandacht besteed aan het verbeteren van de gebitstoestand van basisschoolkinderen. Om een indruk te krijgen van de huidige stand van zaken met betrekking tot de gebitstoestand en de mondgezondheid is in de provincie Drenthe een onderzoek gedaan onder 1.147 kinderen van groep 2 en groep 8. Van de kinderen heeft 33% een niet-gaaf gebit en 13% heeft last van gingivitis. Het hoogste percentage niet-gave gebitten is te vinden onder kinderen uit de lage sociaaleconomische klasse en kinderen uit het speciaal onderwijs. Het blijkt dat deze kinderen minder vaak poetsen, later naar de tandarts gaan en vaker snoepen. De gebitstoestand van kinderen die een poetsinstructie hebben gehad is niet beter dan die van kinderen die geen poetsinstructie hebben gehad. Ook van de kinderen van wie de ouders voorlichting over mondgezondheid hebben gehad, is de gebitstoestand niet beter dan die van kinderen van wie de ouders geen voorlichting hebben gehad.

Impact of Polypharmacy on Health-Related Quality of Life in Dialysis Patients

INTRODUCTION: Dialysis patients are often prescribed a large number of medications to improve metabolic control and manage coexisting comorbidities. However, some studies suggest that a large number of medications could also detrimentally affect patients' health-related quality of life (HRQoL). Therefore, this study aims to provide insight in the association between the number of types of medications and HRQoL in dialysis patients. METHODS: A multicentre cohort study was conducted among dialysis patients from Dutch dialysis centres 3 months after initiation of dialysis as part of the ongoing prospective DOMESTICO study. The number of types of medications, defined as the number of concomitantly prescribed types of drugs, was obtained from electronic patient records. Primary outcome was HRQoL measured with the Physical Component Summary (PCS) score and Mental Component Summary (MCS) score (range 0–100) of the Short Form 12. Secondary outcomes were number of symptoms (range 0–30) measured with the Dialysis Symptoms Index and self-rated health (range 0–100) measured with the EuroQol-5D-5L. Data were analysed using linear regression and adjusted for possible confounders, including comorbidity. Analyses for MCS and number of symptoms were performed after categorizing patients in tertiles according to their number of medications because assumptions of linearity were violated for these outcomes. RESULTS: A total of 162 patients were included. Mean age of patients was 58 ± 17 years, 35% were female, and 80% underwent haemodialysis. The mean number of medications was 12.2 ± 4.5. Mean PCS and MCS were 36.6 ± 10.2 and 46.8 ± 10.0, respectively. The mean number of symptoms was 12.3 ± 6.9 and the mean self-rated health 60.1 ± 20.6. In adjusted analyses, PCS was 0.6 point lower for each additional medication (95% confidence interval [95% CI]: −0.9 to −0.2; p = 0.002). MCS was 4.9 point lower (95% CI: −8.8 to −1.0; p = 0.01) and 1.0 point lower (95% CI: −5.1–3.1; p = 0.63) for the highest and middle tertiles of medications, respectively, than for the lowest tertile. Patients in the highest tertile of medications reported 4.1 more symptoms than in the lowest tertile (95% CI: 1.5–6.6; p = 0.002), but no significant difference in the number of symptoms was observed between the middle and lowest tertiles. Self-rated health was 1.5 point lower for each medication (95% CI: −2.2 to −0.7; p < 0.001). DISCUSSION/CONCLUSION: After adjustment for comorbidity and other confounders, a higher number of medications were associated with a lower PCS, MCS, and self-rated health in dialysis patients and with more symptoms

Leadership Approaches to Negotiate Challenges in a Changing Education Landscape

The argumentative point of departure of this scholarly book is the common conviction of specialists in the field of education in South Africa that the national education system is not at a satisfactory level – in both the academic and the public discourse. Such allegations are made and, frequently, stronger adjectives than ‘non-satisfactory’ are used. Results of international test series in which South Africa has participated, such as the 2015 TIMSS tests, confirm the negative verdicts found in the (public and scholarly) discourse. This book aims to argue that although the lack of performance could be attributed to a multiplicity of factors, one factor that can make a difference in the achievement levels obtained by learners in schools is leadership. The book demonstrates that a particular problem of both the scholarly and the public discourse on education in South Africa is an overtone of defeatism or resignation, blaming all ills in the education system and educational institutions on historical legacies and/or contextual factors (such as socio-economic deprivation in the catchment areas of schools) or poor resources and infrastructure. This collected work was inspired by a recently published spate of articles on top-performing schools (including top-performing schools in rural communities), in which it was demonstrated that good leadership can overcome such contextual and other challenges. The book unpacks the issue of leadership in South African schools from a variety of perspectives, thus contributing to the development of the scholarly discourse on Educational Leadership in South Africa. The target audience of the book is scholars of Educational Leadership. The research reported in the chapters draw on a wide range of methodologies, including empirical (survey) research (questionnaires and interviews), critical literature surveys, and the comparative method
