Prenatal Environmental Exposure to Persistent Organic Pollutants and Indices of Overweight and Cardiovascular Risk in Dutch Adolescents

Persistent organic pollutants (POPs) may have obesogenic effects. Knowledge about the effects of prenatal exposure to POPs on anthropometric measurements and metabolic parameters into adolescence is limited. Therefore, the aim of the current study was to determine whether prenatal environmental exposure to several POPs is associated with indices of overweight and cardiovascular risk in 13-15-year-old children. In this Dutch observational cohort study, 194 mother-infant pairs were included (1998-2002). Maternal pregnancy serum levels of PCBs, OH-PCBs, PBDEs, and other POPs were measured. At follow-up (2014-2016), levels of cholesterol, HDL-C, LDL-C, triglycerides, fasting insulin, fasting glucose, leptin, and adiponectin were measured in their children. The children's height, weight, waist circumference, hip circumference, and blood pressure were measured. In total, 101 adolescents (14.4 ± 0.8 years; 53.7% of invited) participated of which 55 were boys. Mean BMI was 19.1 ± 3.6 kg/m2 and mean BMI z-score 0.13 ± 1.14. Higher prenatal levels of PCBs were associated with lower levels of HDL-C and adiponectin in boys and higher levels of PBDEs with higher triglycerides in girls. We found significant differences by sex in the associations with OH-PCBs, with lower HDL-C and adiponectin, higher LDL-C/HDL-C ratio, fasting glucose, HOMA2-IR, height, and weight for boys. Our study indicates that higher prenatal exposure to PCBs, OH-PCBs, and PBDEs was associated with adolescent levels of some metabolic cardiovascular risk markers and hormones associated with the development of obesity and cardiovascular disease

Effect of a multidisciplinary treatment program on eating behavior in overweight and obese preschool children

Background: The effects of multidisciplinary treatment programs on eating behavior in overweight preschoolaged children are largely unknown. We evaluated a multidisciplinary intervention program on eating behavior in 3- to 5-year-old overweight children, comparing them with children given standard treatment. We also assessed the parental eating behavior changes and investigated associations between parents and children. Methods: We randomized 75 children to a multidisciplinary intervention or to a standard care program. During a 16-week period, children and parents in the multidisciplinary group were given dietary advice, physical activity sessions and, for parents only, psychological counseling. Children and parents in the standard group visited a pediatrician 3 times and were given information on a healthy lifestyle. At baseline, after 16 weeks, and after 12 months, children were measured and parents completed the Dutch Child Eating Behavior Questionnaire (DEBQ-C) for their children and the DEBQ for themselves. Results: At the three time points, 70 (93.3%), 57 (91.9%), and 42 (73.7%) DEBQ-Cs were analyzed. We found no differences in the changes in eating behavior between the two groups over time. In both groups, there was a significant increase in restrained eating behavior present at 16 weeks, however, this was no longer present at 12 months. We found no associations between changes in eating behavior between the children and their parents. Conclusions: A multidisciplinary obesity intervention program in preschool-aged children induced more restrained eating behavior between baseline and 16 weeks. However, there was no difference with the children in the standard care group

Parental correlations of physical activity and body mass index in young children-the GECKO Drenthe cohort

Background: Parental behavior can influence the development of overweight in children. The aim of this study is to examine whether parental BMI and parental physical activity are associated with BMI, waist circumference and physical activity in young children. Methods: In 3-4 year old children, weight, height and waist circumference were measured. Children's physical activity was measured in a subgroup (n = 299) using a tri-axial activity monitor, TracmorD. Data are represented as activity counts per minute (total physical activity) and as percentage of time in sedentary, light, moderate and vigorous intensity physical activity (generated from a subsample of Actigraph data using cut points from Butte et al.). Parental weight and height were self-reported and parental physical activity was assessed by the validated questionnaire SQUASH. Results: In total 1554 children (age 3.9 +/- 0.1 years, BMI 15.8 +/- 1.3 kg/m2 and waist circumference 52.4 +/- 3.5 cm) were included. Eleven percent were overweight or obese. A higher maternal BMI was related to higher levels of children's sedentary activity (r = 0.120, p = 0.04 and to lower levels of children's total and moderate physical activity (r = -0.158, p = 0.007 and r = -0.154, p = 0.008, respectively). Parental BMI was positively correlated with children's BMI and waist circumference (r = 0.20-0.27, p <0.001). Higher maternal total physical activity levels were not related to children's total physical activity level, but were related to higher levels of children's moderate and vigorous physical activity (rho = 0.132, p = 0.046 and rho = 0.132, p = 0.046, respectively). No correlations between total, moderate or vigorous physical activity levels of the parents with the child's BMI or waist circumference were found. Looking at physical activity domains maternal physical activity in active commuting, either walking or biking, showed a negative correlation with BMI of the child (rho = -0.062, p = 0.042). Conclusions: Higher maternal BMI and lower maternal physical activity levels were related to lower levels of children's physical activity. More active commuting by the mother and a lower parental BMI were related to a lower BMI of the children. Energy-balance related behavior of the parents may contribute to a healthier BMI of both preschool children and their parents

Duration of Breastfeeding in Late Preterm Infants:Maternal and Infant Factors

Background More than 550,000 late preterm infants are born each year in Indonesia. These infants, born between 34(0/7)-36(6/7) weeks, have more complications than term infants. Breastfeeding is considered the most optimal nutrition for newborn infants. Two groups of factors are important for successful breastfeeding: infant and maternal factors. The infant factors can be evaluated using the Infant Breastfeeding Assessment Tool and the maternal aspects with the Breastfeeding Self-Efficacy Scale-Short Form. Aim To determine whether the Infant Breastfeeding Assessment Tool or the Breastfeeding Self-Efficacy Scale-Short Form was more predictive of successful breastfeeding among late preterm infants. Methods This study was conducted in the Academic Teaching Hospital in Surabaya, Indonesia in March-July 2017. Mothers who delivered their infant between a gestational age of 34(0/7) and 36(6/7) weeks were included. Results Fifty-four single born participant mother-infant pairs were included. The mean total Breastfeeding Self-Efficacy Scale-Short Form score was 57.8 (SD = 8.9). The mean Infant Breastfeeding Assessment Tool score was 8.3 (SD = 1.8). There was a significant correlation between the total Breastfeeding Self-Efficacy Scale-Short Form score and the Infant Breastfeeding Assessment Tool score (p = .020, r = 0.316). The Breastfeeding Self-Efficacy Scale-Short Form was significantly higher in the participant (mothers) of the infants breastfed >= 4 months, compared to < 4 months, 61.59 (SD = 5.78) versus 51.78 (SD = 11.64; p = .001). No correlation was found between the duration of breastfeeding and Infant Breastfeeding Assessment Tool score (p = .087) Conclusion Maternal factors were more important for successful breastfeeding in these late preterm infants than infant factors in our sample

Physical activity in children with Juvenile Idiopathic Arthritis compared to controls

BACKGROUND: To compare physical activity (PA) in children with juvenile idiopathic arthritis (JIA) with controls and to analyse the effect of disease specific factors on PA in children with JIA treated according to current treatment regimes. METHODS: PA was measured with a 7-day activity diary and expressed as physical activity level (PAL). Moderate to vigorous physical activity (MVPA) (hours/day) and sedentary time (hours/day) was determined. In children with JIA, medication, the number of swollen and/or painful joints, disease activity, functional ability, pain and well-being was determined. Multivariate regression analysis was performed to analyze differences in PA between JIA and controls, adjusted for influences of age, gender, season, Body Mass Index (BMI) and to analyze predictors of PA in JIA patients. RESULTS: Seventy-six children with JIA (26 boys and 50 girls, mean ± SD age 10.0 ± 1.4 years) and 131 controls (49 boys and 82 girls, mean ± SD age 10.4 ± 1.2 years) participated in this study. Children with JIA had a significantly lower PAL (0.10, p = 0.01) corrected for age, BMI, gender and season. They spent less time in MVPA (0.41 h/day, p = 0.06) and had a significantly higher mean time spent in sedentary activities (0.59 h/day, p 0.02) compared to controls. The activity level of children with JIA was related to age, gender, season, feeling of well-being and pain. CONCLUSION: Children with JIA have a lower PAL, spent less time in MVPA and spent more time on sedentary activities compared to controls despite current medical treatment and PA encouragement. TRIAL REGISTRATION: Data of the children with JIA are from the Rheumates@work study ISRCTN92733069

The incidence of osteopenia of prematurity in preterm infants without phosphate supplementation A prospective, observational study:A prospective, observational study

ABSTRACT: To meet their requirements for bone mineralization, it is recommended that preterm infants receive nutritional support containing calcium and phosphate. There are no clear data on the incidence of osteopenia of prematurity (OFP) in preterm infants without phosphate supplementation.This study aimed to investigate the incidence of OFP in preterm infants without phosphate supplementation and its relationship with the duration of parenteral nutrition (PN).This was a prospective and observational study.This study included 30 infants aged 15 days significantly increased the risk of OFP (odds ratio, 5.40; 95% confidence interval, 1.12-26.04; P = .035).We found a high incidence of OFP in preterm infants without phosphate supplementation. An association was found between the duration of PN and the incidence of OFP. Further research is needed to prevent the development of osteopenia in preterm infants

Limitations of Dutch Growth Research Foundation Commercial Software Weight Velocity for Age Standard Deviation Score

BACKGROUND The commercial software for hospitals, Weight Velocity for Age Standard Deviation Score (SDSWVA), claims to document the growth and development of children, although published details are unavailable. The statistics-derived parameter SDSWVA includes the weight velocity at age t, WV(t) (weight gained between t and (t-1.23) years, divided by 1.23), and 3 standard weight velocity curves at average age AA, defined as AA=t-1.23/2 years. SDSWVA denotes the number of standard deviations that WV(t) deviates from the 0 SD weight velocity at AA. WV(t) yielded erroneous outcomes when applied to weights of a seriously underweight boy with an allergy to cows' milk who showed strong weight growth after being fed on food free of cows' milk. The SDSWVA software tacitly suggests that it is more accurate than WV(t). CASE REPORT The case of this boy was previously described in this Journal. Using SDSWVA(t,AA) software, his weight growth was analyzed by his third pediatrician, beginning at age 1.5 years. The diagnosis of the mother with Pediatric Condition Falsification was confirmed, adding 6 months to foster care, which totalled 8.5 months. Testing of the SDSWVA software on the boy's weight curve yielded results that were complex, nontransparent, and as erroneous as WV(t), explaining the misdiagnosis by the third pediatrician. CONCLUSIONS SDSWVA software should not be used for children under 3 years and during variable weight behavior. Erroneous performance, unpublished details, and an error identified in their new but untested software make the Dutch Growth Research Foundation unlikely to meet the 2020 European Union regulations for in vitro medical devices

Multicentre survey of retinopathy of prematurity in Indonesia

Background: The incidence of retinopathy of prematurity (ROP) is higher in Indonesia than in high-income countries. In order to reduce the incidence of the disease, a protocol on preventing, screening and treating ROP was published in Indonesia in 2010. To assist the practical implementation of the protocol, meetings were held in all Indonesia regions, calling attention to the high incidence of ROP and the methods to reduce it. In addition, national health insurance was introduced in 2014, making ROP screening and treatment accessible to more infants. Objective: To evaluate whether the introduction of both the guideline drawing attention to the high incidence of ROP and national health insurance may have influenced the incidence of the disease in Indonesia. Setting: Data were collected from 34 hospitals with different levels of care: national referral centres, university-based hospitals, and public and private hospitals. Methods: A survey was administered with questions on admission numbers, mortality rates, ROP incidence, and its stages for 2016-2017 in relation to gestational age and birth weight. Results: We identified 12 115 eligible infants with a gestational age of less than 34 weeks. Mortality was 24% and any stage ROP 6.7%. The mortality in infants aged less than 28 weeks was 67%, the incidence of all-stage ROP 18% and severe ROP 4%. In the group aged 28-32 weeks, the mortality was 24%, all-stage ROP 7% and severe ROP 4%-5%. Both mortality and the incidence of ROP were highest in university-based hospitals. Conclusions: In the 2016-2017 period, the infant mortality rate before 32 weeks of age was higher in Indonesia than in high-income countries, but the incidence of ROP was comparable. This incidence is likely an underestimation due to the high mortality rate. The ROP incidence in 2016-2017 is lower than in surveys conducted before 2015. This decline is likely due to a higher practitioner awareness about ROP and national health insurance implementation in Indonesia
