Protocol to evaluate the effectiveness and cost-effectiveness of an environmental nutrition and physical activity intervention in nurseries (Nutrition and Physical Activity Self Assessment for Child Care - NAP SACC UK): a multicentre cluster randomised controlled trial.

BACKGROUND: One in seven UK children have obesity when starting school, with higher prevalence associated with deprivation. Most pre-school children do not meet UK recommendations for physical activity and nutrition. Formal childcare settings provide opportunities to deliver interventions to improve nutritional quality and physical activity to the majority of 3-4-year-olds. The nutrition and physical activity self-assessment for childcare (NAP SACC) intervention has demonstrated effectiveness in the USA with high acceptability in the UK. The study aims to evaluate the effectiveness and cost-effectiveness of the NAP SACC UK intervention to increase physical activity, reduce sedentary time and improve nutritional intake. METHODS: Multi-centre cluster RCT with process and economic evaluation. Participants are children aged 2 years or over, attending UK early years settings (nurseries) for ≥ 12 h/week or ≥ 15 h/week during term time and their parents, and staff at participating nurseries. The 12-month intervention involves nursery managers working with a Partner (public health practitioner) to self-assess policies and practices relating to physical activity and nutrition; nursery staff attending one physical activity and one nutrition training workshop and setting goals to be achieved within 6 months. The Partner provides support and reviews progress. Nursery staff receive a further workshop and new goals are set, with Partner support for a further 6 months. The comparator is usual practice. Up to 56 nurseries will be stratified by area and randomly allocated to intervention or comparator arm with minimisation of differences in level of deprivation. PRIMARY OUTCOMES: accelerometer-assessed mean total activity time on nursery days and average total energy (kcal) intake per eating occasion of lunch and morning/afternoon snacks consumed within nurseries. SECONDARY OUTCOMES: accelerometer-assessed mean daily minutes of moderate-to-vigorous physical activity and sedentary time per nursery day, total physical activity on nursery days compared to non-nursery days, average serving size of lunch and morning/afternoon snacks in nursery per day, average percentage of core and non-core food in lunch and morning/afternoon snacks, zBMI, proportion of children who are overweight/obese and child quality-of-life. A process evaluation will examine fidelity, acceptability, sustainability and context. An economic evaluation will compare costs and consequences from the perspective of the local government, nursery and parents. TRIAL REGISTRATION: ISRCTN33134697, 31/10/2019.

Quality of Life at a 10-Year Follow-Up of Children Born Preterm with Post-Hemorrhagic Ventricular Dilatation: A Cohort Study.

BACKGROUND: Post-haemorrhagic ventricular dilatation (PHVD) is commonly seen in extremely preterm babies, carries significant morbidity, and may cause neonatal mortality. There is a lack of literature on the subsequent health-related quality of life (HRQoL) in childhood. The aim of this work was to assess the quality of life of preterm babies after PHVD at 10 years of age using two validated questionnaires. METHODS: Children with PHVD were assessed as part of the 10-year follow-up of the drainage, irrigation, and fibrinolytic therapy trial. The HRQoL outcome was measured using parent-reported EQ-5D-5L and HUI-3 questionnaires. Both questionnaires produce a summary score anchored at 1 (best health) and 0 (equivalent to death). RESULTS: Median scores at follow-up were 0.65 (IQR 0.36-0.84; n = 44) for the EQ-5D-5L and 0.52 (IQR 0.22-0.87; n = 51) for the HUI-3. Similar proportions had a score below 0.2 (HRQoL [20%], HUI-3 [21%]), while 20% had a HRQoL score above 0.80 compared to 34% using HUI-3. The most severe problems from the EQ-5D-5L were reported in the self-care, mobility, and activity domains, while the HUI-3 reported worse problems in ambulation, cognition, and dexterity domains. Infants with worse (grade 4) intraventricular haemorrhage had poorer HRQoL than those with grade 3 bleeds. CONCLUSION: Children who survive to 10 years of age after PHVD have on average lower HRQoL than their peers. However, the reported range is wide, with a quarter of the children having scores above 0.87 (similar to population norms), while a fifth have very low HRQol scores. Impact was not uniform across domains, with mobility/ambulation a concern across both measures.

Is the mattress important in helping babies keep warm?--Paradoxical effects of a sleeping surface with negligible thermal resistance.

BACKGROUND: Heavy wrapping and head covering are risk factors for Sudden Infant Death Syndrome. A new mattress construction, PurFlo, has extremely low thermal resistance, and when used with an infant sleeping bag minimizes the risk of head covering. AIM: To investigate the thermal balance and metabolic rate of infants sleeping on a conventional mattress or a Purflo mattress in infant sleeping bags. METHODS: A longitudinal study of thermal balance of infants during day-time sleep on both mattress types in thermoneutral and cool conditions at ages 3 weeks (n = 24), 3 months (n = 22) and 5 months (n = 18). RESULTS: In thermoneutral conditions axillary temperatures in quiet sleep were lower on the conventional mattress than on the PurFlo mattress (p < 0.05, Wilcoxon test). On lowering room temperature to 15-16 degrees C axillary temperatures fell, particularly in the older babies, and at each age were lower on the conventional mattress than the Purflo (differences 0.14-0.72 degrees C, p < 0.05, Wilcoxon test). CONCLUSION: In both thermoneutral and cool conditions, infant temperatures were higher on the PurFlo than the conventional mattress. The more deformable surface of the PurFlo mattress may lead to more effective insulation by the sleeping bag despite a lack of mattress insulation.
