Exercise in pregnancy: 1-year and 7-year follow-ups of mothers and offspring after a randomized controlled trial. Sci Rep 2018; 8:12915. [PMID: 30150651 PMCID: PMC6110723 DOI: 10.1038/s41598-018-30925-5] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2017] [Accepted: 07/20/2018] [Indexed: 01/21/2023] Open
Abstract
There are limited data on long-term outcomes of mothers or their offspring following exercise interventions during pregnancy. We assessed long-term effects of an exercise intervention (home-based stationary cycling) between 20–36 weeks of gestation on anthropometry and body composition in mothers and offspring after 1 and 7 years. 84 women were randomised to intervention or usual activity, with follow-up data available for 61 mother-child pairs (38 exercisers) at 1 year and 57 (33 exercisers) at 7 years. At 1 year, there were no observed differences in measured outcomes between mothers and offspring in the two groups. At the 7-year follow-up, mothers were mostly similar, except that exercisers had lower systolic blood pressure (−6.2 mmHg; p = 0.049). However, offspring of mothers who exercised during pregnancy had increased total body fat (+3.2%; p = 0.034) and greater abdominal (+4.1% android fat; p = 0.040) and gynoid (+3.5% gynoid fat; p = 0.042) adiposity compared with controls. Exercise interventions beginning during pregnancy may be beneficial to long-term maternal health. However, the initiation of exercise during pregnancy amongst sedentary mothers may be associated with adverse effects in the offspring during childhood. Larger follow-up studies are required to investigate long-term effects of exercise in pregnancy.

Abstract
Socioeconomic status is a known determinant of health. In secondary data analyses, we assessed whether socioeconomic status affected health-related quality of life in a group of overweight (body mass index 25–30 kg/m2) middle-aged (45.9 ± 5.4 years) men, recruited in Auckland (New Zealand). Health-related quality of life was assessed with SF-36v2 three times: at baseline, and 12 and 30 weeks later. Socioeconomic status was determined by geo-coded deprivation scores derived from current address using the New Zealand Index of Deprivation 2006 (NZDep2006), as well as capital value of residence. Univariable and multivariable analyses showed no associations between measures of socioeconomic status and any mental or physical health domains. Our findings may reflect the fact that these men are not currently experiencing comorbidities associated with overweight.

Abstract
BACKGROUND Repeat dose(s) of antenatal betamethasone are recommended for women at <32 weeks with ongoing risk of preterm birth. However, there is concern that use of repeat dose(s) in fetal growth restriction (FGR) may increase the risk of later cardiometabolic disease. METHODS We undertook secondary analysis of data from the Australasian Collaborative Trial of Repeat Doses of Corticosteroids Midchildhood Outcome Study to determine if FGR influences the effect of repeat betamethasone on growth and cardiometabolic function. At 6 to 8 years, children underwent anthropometry, dual energy x-ray absorptiometry, intravenous glucose tolerance testing, ambulatory blood pressure monitoring, and spirometry. FGR was defined as severe FGR at entry, cesarean delivery for FGR, or customized birth weight below the third centile. RESULTS Of 266 children assessed, FGR occurred in 43 of 127 (34%) exposed to repeat betamethasone and 44 of 139 (32%) exposed to placebo. There was an interaction between FGR and repeat betamethasone treatment for the effect on height (z score mean difference [95% confidence interval]; FGR: 0.59 [0.01 to 1.17]; non-FGR: -0.29 [-0.69 to 0.10]; P = .01). However, FGR did not influence the effect of repeat betamethasone on cardiometabolic function, which was similar in treatment groups, both in FGR and non-FGR subgroups. CONCLUSIONS Repeat antenatal betamethasone treatment had no adverse effects on cardiometabolic function, even in the presence of FGR. It may have a positive effect on height in FGR. Clinicians should use repeat doses of antenatal corticosteroids when indicated before preterm birth, regardless of FGR, in view of the associated neonatal benefits.

Abstract
OBJECTIVE To determine whether Whānau Pakari, a home-based, 12-month multi-disciplinary child obesity intervention programme was cost-effective when compared with the prior conventional hospital-based model of care. METHODS Whānau Pakari trial participants were recruited January 2012-August 2014, and randomised to either a high-intensity intervention (weekly sessions for 12 months with home-based assessments and advice, n=100) or low-intensity control (home-based assessments and advice only, n=99). Trial participants were aged 5-16 years, resided in Taranaki, Aotearoa/New Zealand (NZ), with a body mass index (BMI) ≥98th centile or BMI >91st centile with weight-related comorbidities. Conventional group participants (receiving paediatrician assessment with dietitian input and physical activity/nutrition support, n=44) were aged 4-15 years, and resided in the same or another NZ centre. The change in BMI standard deviation score (SDS) at 12 months from baseline and programme intervention costs, both at the participant level, were used for the economic evaluation. A limited health funder perspective with costs in 2016 NZ$ was taken. RESULTS The per child 12-month Whānau Pakari programme costs were significantly lower than in the conventional group. In the low-intensity group, costs were NZ$939 (95% CI: 872, 1007) (US$648) lower than the conventional group. In the high-intensity intervention group, costs were NZ$155 (95% CI: 89, 219) (US$107) lower than in the conventional group. BMI SDS reductions were similar in the three groups. CONCLUSIONS A home-based, multi-disciplinary child obesity intervention had lower programme costs per child, greater reach, with similar BMI SDS outcomes at 12 months when compared with the previous hospital-based conventional model.

Abstract
Obesity is highly prevalent in children under the age of 5 years, although its identification in infants under 2 years remains difficult. Several clinical prediction models have been developed for obesity risk in early childhood, using a number of different predictors. The predictive capacity (sensitivity and specificity) of these models varies greatly, and there is no agreed risk threshold for the prediction of early childhood obesity. Of the existing models, only two have been practically utilized, but neither have been particularly successful. This commentary suggests how future research may successfully utilize existing early childhood obesity prediction models for intervention. We also consider the need for such models, and how targeted obesity intervention may be more effective than population-based intervention.

Abstract
Pre-eclampsia is a common pregnancy disorder with important short-term complications for mother and baby. Evidence suggests pre-eclampsia also has implications for the mother beyond pregnancy, as well as long-term effects on offspring health. Limited research has linked pre-eclampsia with changes in offspring blood pressure, BMI, and stroke risk. Underpinning mechanisms are poorly understood, but developmental programming may be involved. Research in this area has been hindered by difficulties in defining pre-eclampsia and problems with study design. Further targeted evaluation through to adulthood is required to determine the long-term impact of pre-eclampsia on offspring disease risk and how this develops.

Abstract
Antibiotics have been hailed by many as "miracle drugs" that have been effectively treating infectious diseases for over a century, leading to a marked reduction in morbidity and mortality. However, with the increasing use of antibiotics, we are now faced not only with the increasing threat of antibiotic resistance, but also with a rising concern about potential long-term effects of antibiotics on human health, including the development of obesity. The obesity pandemic continues to increase, a problem that affects both adults and children alike. Disruptions to the gut microbiome have been linked to a multitude of adverse conditions, including obesity, type 2 diabetes, inflammatory bowel diseases, anxiety, autism, allergies, and autoimmune diseases. This review focuses on the association between antibiotics and obesity, and the role of the gut microbiome. There is strong evidence supporting the role of antibiotics in the development of obesity in well-controlled animal models. However, evidence for this link in humans is still inconclusive, and we need further well-designed clinical trials to clarify this association.

Abstract
BACKGROUND We aimed to evaluate metabolic outcomes in overweight/obese nulliparous and multiparous women and their offspring. STUDY DESIGN Seventy-two overweight and obese women who participated in a randomized controlled trial of exercise in pregnancy were included in the study, comparing 18 nulliparous and 54 multiparous women and their singleton offspring. Women were assessed at 19 and 36 weeks of gestation. Fetal growth was measured using standard obstetric ultrasound techniques. Cord blood was collected at birth. Maternal and offspring body composition was assessed using DXA ~2 weeks after delivery. RESULTS Nulliparous women had higher HbA1c in the third trimester of pregnancy than multiparous women (5.48% vs 5.29%; P=.002) and were more insulin-resistant based on the surrogate marker sex hormone-binding globulin (354 vs 408 nmol/L; P=.047). Nulliparous women also had higher levels of the inflammatory marker tumour necrosis factor-alpha (4.74 vs 3.62 pg/mL; P=.025). At birth, the offspring of nulliparous women were on average 340 g (P=.013) and 0.69 standard deviation scores (P=.026) lighter than those born of multiparous women. Cord blood data showed lower insulin-like growth factor-II (P=.026) and higher IGF binding protein-1 (P=.002) levels in the offspring of nulliparous women. In addition, a less favourable metabolic profile was observed in the offspring of nulliparous women, as indicated by higher triglyceride (P<.001) and interleukin-6 (P=.039) concentrations. CONCLUSIONS Infants born of nulliparous overweight and obese women appear to be exposed to a less favourable metabolic environment in utero, with evidence of subtle adverse metabolic outcomes at birth compared to infants of overweight/obese multiparous women.

Abstract
OBJECTIVE To report 12-month outcomes from a multidisciplinary child obesity intervention program, targeting high-risk groups. METHODS In this unblinded randomized controlled trial, participants (recruited January 2012-August 2014) were aged 5 to 16 years, resided in Taranaki, Aotearoa/New Zealand, and had BMI ≥ 98th percentile or BMI > 91st percentile with weight-related comorbidities. Randomization was by minimization (age and ethnicity), with participants assigned to an intense intervention group (home-based assessments at 6-month intervals and a 12-month multidisciplinary program with weekly group sessions) or to a minimal-intensity control group with home-based assessments and advice at each 6-month follow-up. The primary outcome was the change in BMI standard deviation score (SDS) at 12 months from baseline. A mixed model analysis was undertaken, incorporating all 6- and 12-month data. RESULTS Two hundred and three children were randomly assigned (47% Māori, 43% New Zealand European, 53% female, 28% from the most deprived quintile, mean age 10.7 years, mean BMI SDS 3.12). Both groups displayed a change in BMI SDS at 12 months from baseline (-0.12 control, -0.10 intervention), improvements in cardiovascular fitness (P < 0.0001), and improvements in quality of life (P < 0.001). Achieving ≥ 70% attendance in the intense intervention group resulted in a change in BMI SDS of -0.22. CONCLUSIONS This program achieved a high recruitment of target groups and a high rate of BMI SDS reduction, irrespective of intervention intensity. If retention is optimized, the intensive program doubles its effect.

Abstract
BACKGROUND There has been little change in the incidence of diabetic ketoacidosis (DKA) in newly diagnosed type 1 diabetes mellitus (T1DM) in children and adolescents in most developed countries. OBJECTIVES To assess potentially modifiable antecedents of DKA in children <15 years of age with new onset T1DM. METHODS Retrospective review of prospectively collected data from a complete regional cohort of children with T1DM in Auckland (New Zealand) from 2010 to 2014. DKA and severity were defined according to the ISPAD 2014 guidelines. RESULTS A total of 263 children presented with new onset T1DM during the 5-year study period at 9.0 years of age (range 1.0-14.7), of whom 61% were NZ-European, 14% Maori, 13% Pacifica, and 11% other. A total of 71 patients (27%) were in DKA, including 31 mild, 20 moderate, and 20 severe DKA. DKA was associated with no family history of T1DM, higher glycated hemoglobin (HbA1c) values at presentation, self-presenting to secondary care, health care professional contacts in the 4 weeks before final presentation, and greater deprivation. Although a delay in referral from primary care for laboratory testing was common (81/216), only delay for more than 48 hours was associated with increased risk of DKA (11/22 > 48 h vs 12/59 referred at <48 h, P = .013). CONCLUSIONS These data suggest that in addition to lack of family awareness potentially modifiable risk factors for new onset DKA include prolonged delay for laboratory testing and a low index of medical suspicion for T1DM leading to delayed diagnosis.

Abstract
BackgroundGestation is a crucial timepoint in human development. Deviation from a term gestational age correlates with both acute and long-term adverse health effects for the child. Both being born preterm and post-term, that is, having short and long gestational ages, are heritable and influenced by the prenatal and perinatal environment. Despite the obvious heritable component, specific genetic influences underlying differences in gestational age are poorly understood.MethodsWe investigated the genetic architecture of gestational age in 9141 individuals, including 1167 born post-term, across two Northern Finland cohorts born in 1966 or 1986.ResultsHere we identify one globally significant intronic genetic variant within the ADAMTS13 gene that is associated with prolonged gestation (p=4.85×10−8). Additional variants that reached suggestive levels of significance were identified within introns at the ARGHAP42 and TKT genes, and in the upstream (5’) intergenic regions of the B3GALT5 and SSBP2 genes. The variants near the ADAMTS13, B3GALT5, SSBP2 and TKT loci are linked to alterations in gene expression levels (cis-eQTLs). Luciferase assays confirmed the allele specific enhancer activity for the BGALT5 and TKT loci.ConclusionsOur findings provide the first evidence of a specific genetic influence associated with prolonged gestation. This study forms a foundation for a better understanding of the genetic and long-term health risks faced by induced and post-term individuals. The long-term risks for induced individuals who have a previously overlooked post-term potential may be a major issue for current health providers.

Abstract
OBJECTIVE To determine the impact of 20 weeks of exercise training in aerobic capacity on left ventricular function and glycemic control in adolescents with and without type 1 diabetes. RESEARCH DESIGN AND METHODS Fifty-three adolescents with type 1 diabetes (aged 15.6 years) were divided into two groups: exercise training (n = 38) and nontraining (n = 15). Twenty-two healthy adolescents without diabetes (aged 16.7 years) were included and, with the 38 participants with type 1 diabetes, participated in a 20-week exercise-training intervention. Assessments included VO2max and body composition. Left ventricular parameters were obtained at rest and during acute exercise using MRI. RESULTS Exercise training improved aerobic capacity (10%) and stroke volume (6%) in both trained groups, but the increase in the group with type 1 diabetes remained lower than trained control subjects. Increased stroke volume in adolescents with type 1 diabetes resulted from greater left ventricular contractility (9% increase in ejection fraction and an 11% reduction in end-systolic volumes) and, to a lesser extent, improved left ventricular filling (6%), suggesting that impaired diastolic function can be affected by exercise training in adolescents with type 1 diabetes. Insulin use decreased by ∼10%, but no change in glycemic status was observed. CONCLUSIONS These data demonstrate that in adolescents, the impairment in left ventricular function seen with type 1 diabetes can be improved, although not normalized, with regular intense physical activity. Importantly, diastolic dysfunction, a common mechanism causing heart failure in older subjects with diabetes, appears to be partially reversible in this age group.

Abstract
OBJECTIVE To describe health-related quality of life (HRQOL) and psychological well-being of children and adolescents at enrolment in a multidisciplinary community-based obesity programme and to determine association with ethnicity. This programme targeted indigenous people and those from most deprived households. Further, this cohort was compared with other populations/normative data. METHODS This study examines baseline demographic data of an unblinded randomised controlled clinical trial. Participants (recruited from January 2012-August 2014) resided in Taranaki, New Zealand, and for this study we only included those with a body mass index (BMI) ≥98th percentile (obese). HRQOL and psychological well-being were assessed using the Pediatric Quality of Life Inventory (PedsQL V.4.0TM) (parent and child reports), and Achenbach's Child Behavior Checklist (CBCL)/Youth Self Report (YSR). RESULTS Assessments were undertaken for 233 participants (45% Māori, 45% New Zealand European, 10% other ethnicities, 52% female, 30% from the most deprived household quintile), mean age 10.6 years. The mean BMI SD score (SDS) was 3.12 (range 2.01-5.34). Total PedsQL generic scaled score (parent) was lower (mean=63.4, SD 14.0) than an age-matched group of Australian children without obesity from the Health of Young Victorians study (mean=83.1, SD 12.5). In multivariable models, child and parental generic scaled scores decreased in older children (β=-0.70 and p=0.031, β=-0.64 and p=0.047, respectively). Behavioural difficulties (CBCL/YSR total score) were reported in 43.5% of participants, with the rate of emotional/behavioural difficulties six times higher than reported norms (p<0.001). CONCLUSIONS In this cohort, children and adolescents with obesity had a low HRQOL, and a concerning level of psychological difficulties, irrespective of ethnicity. Obesity itself rather than ethnicity or deprivation appeared to contribute to lower HRQOL scores. This study highlights the importance of psychologist involvement in obesity intervention programmes.

Abstract
BACKGROUND AND OBJECTIVE Treatment of women at risk for preterm birth with repeat doses of glucocorticoids reduces neonatal morbidity, but could have adverse effects on skeletal development. We assessed whether exposure to repeat antenatal betamethasone alters bone mass in children whose mothers participated in the Australasian Collaborative Trial of Repeat Doses of Corticosteroids. METHODS Women were randomized to a single dose of betamethasone or placebo, ≥7 days after an initial course of glucocorticoids, repeated each week that they remained at risk for preterm birth at <32 weeks' gestation. In this follow-up study, children underwent whole-body dual-energy radiograph absorptiometry at 6 to 8 years' corrected age. RESULTS Of 212 eligible childhood survivors, 185 were studied (87%; 91 repeat betamethasone group; 94 placebo [single course] group). Children exposed to repeat antenatal betamethasone and those exposed to placebo had similar whole-body bone mineral content (median repeat betamethasone: 553 g, interquartile range: 442-712 g; placebo: 567 g, interquartile range: 447-750 g; geometric mean ratio: 0.99; 95% confidence interval: 0.94-1.03, P = .55) and bone area (median repeat betamethasone 832 cm2, interquartile range: 693-963 cm2; placebo: 822 cm2, interquartile range: 710-1020 cm2; geometric mean ratio: 0.99, 95% confidence interval: 0.92-1.07, P = .75). CONCLUSIONS Exposure to repeat doses of antenatal betamethasone compared with a single course of glucocorticoids does not alter bone mass in mid-childhood.

Abstract
We examined whether being born preterm was associated with changes in adult anthropometry in women. We assessed data on 201,382 women (born in 1973-1988) from the Swedish Birth Register. The mean age was 26.0 years. Of the women in our cohort, 663 were born very preterm (<32 weeks of gestation), 8,247 were born moderately preterm (at least 32 weeks but <37 weeks), and 192,472 were born at term (37-41 weeks). Subgroup analyses were carried out among siblings and also after adjustment for maternal anthropometric data. Statistical tests were 2-sided. Decreasing gestational age was associated with lower height (-1.1 mm per week of gestation; P < 0.0001), so that women who were born very preterm were on average 12 mm shorter than women who were born moderately preterm (P < 0.0001) and 17 mm shorter than women born at term (P < 0.0001). Compared with women who were born at term, those who were born very preterm had 2.9 times higher odds of short stature (<155.4 cm), and those born moderately preterm had 1.43 times higher odds. Subgroup analyses showed no differences between women born moderately preterm and those born at term but accentuated differences from women born very preterm. Among siblings (n = 2,388), very preterm women were 23 mm shorter than those born at term (P = 0.003), with a 20-mm difference observed in subgroup analyses (n = 27,395) that were adjusted for maternal stature (P < 0.001). A shorter final height was associated with decreasing gestational age, and this association was particularly marked in women born very preterm.

Abstract
There is increasing evidence that the sex of the foetus may alter the maternal metabolic milieu during pregnancy. Following a randomized controlled trial of exercise in overweight and obese pregnant women, we assessed whether the sex of the foetus was associated with changes in maternal metabolism. Data were analysed on 74 randomized participants who completed the trial, including 38 mothers carrying males and 36 mothers carrying females. At 19 weeks of gestation, mothers carrying boys had higher blood glucose concentrations than those carrying girls (5.4 vs 4.9 mmol/l; p = .046). At 36 weeks of gestation, differences were more marked, with blood glucose concentrations 15% higher in mothers carrying females (5.7 vs 5.0 mmol/l; p = .004). In addition, mothers carrying girls had higher concentrations of hs-CRP across pregnancy (5.0 vs 3.6 mg/l; p = .029). Our findings provide further evidence that the sex of the foetus appears to influence maternal metabolism.

Abstract
AIM The aim of this study was to describe the characteristics at enrolment of children and adolescents referred to an obesity programme and to determine how the prevalence of comorbidities differed in Indigenous versus non-Indigenous children. METHODS Participants were residents of a semi-rural region of New Zealand (NZ). Eligibility was defined by a body mass index (BMI) of ≥98th percentile or >91st centile with weight-related comorbidities. Fasting blood, medical and physical assessments were obtained. RESULTS During the recruitment period from January 2012 to August 2014, 239 participants, aged 4.8-16.8 years, undertook assessment. Average BMI standard deviation score was 3.09 (standard deviation (SD) = 0.60, range 1.52-5.34 SD). The majority of participants were of either Maori (NZ's indigenous people (45%)) or NZ European (45%) ethnicity; 29% of participants were from the most deprived quintile of household deprivation. Maori participants were more likely than NZ Europeans to have a mother who smoked during pregnancy (52% vs. 28%, P = 0.001), a family history of type 2 diabetes (66% vs. 53%, P = 0.04), acanthosis nigricans on examination (58% vs. 20%, P < 0.0001), a low serum high-density lipoprotein cholesterol (27% vs. 14%, P = 0.03) or high serum triglyceride (38% vs. 24%, P = 0.03) concentration. CONCLUSION The unique aspect of this study was the ability to recruit high levels of Maori participants and those from most deprived areas, indicating a high level of acceptability for these target groups. Comorbidities were prevalent in this cohort of overweight/obese school-aged children. While there were some differences in comorbidity prevalence between Maori and NZ Europeans, the overall clinical picture in our cohort, irrespective of ethnicity, was of concern.

Abstract
Objectives The aim of this study was to describe dietary intake and eating behaviours of obese children and adolescents, and also to determine how these differ in Indigenous versus non-Indigenous children at enrolment in an obesity programme. Methods Baseline dietary intake and eating behaviour records were assessed from those enrolled in a clinical unblinded randomised controlled trial of a multi-disciplinary intervention. The setting was a community-based obesity programme in Taranaki, New Zealand. Children or adolescents who were enrolled from January 2012 to August 2014, with a BMI ≥98th percentile or >91st centile with weight-related comorbidities were eligible. Results 239 participants (45% Māori, 45% NZ Europeans, 10% other ethnicities), aged 5–17 years were assessed. Two-thirds of participants experienced hyperphagia and half were not satiated after a meal. Comfort eating was reported by 62% of participants, and daily energy intake was above the recommended guidelines for 54%. Fruit and vegetable intake was suboptimal compared with the recommended 5 servings per day (mean 3.5 [SD = 1.9] servings per day), and the mean weekly breakfasts were less than the national average (5.9 vs 6.5; p<0.0001). Median sweet drink intake amongst Māori was twice that of NZ Europeans (250 vs 125 ml per day; p = 0.0002). Conclusions There was a concerning prevalence of abnormal eating behaviours and significant differences in dietary intake between obese participants and their national counterparts. Ethnic differences between Indigenous and non-Indigenous participants were also present, especially in relation to sweet drink consumption. Eating behaviours, especially sweet drink consumption and fruit/vegetable intake need to be addressed.

Abstract
Fish oil is commonly taken by pregnant women, and supplements sold at retail are often oxidized. Using a rat model, we aimed to assess the effects of supplementation with oxidized fish oil during pregnancy in mothers and offspring, focusing on newborn viability and maternal insulin sensitivity. Female rats were allocated to a control or high-fat diet and then mated. These rats were subsequently randomized to receive a daily gavage treatment of 1 ml of unoxidized fish oil, a highly oxidized fish oil, or control (water) throughout pregnancy. At birth, the gavage treatment was stopped, but the same maternal diets were fed ad libitum throughout lactation. Supplementation with oxidized fish oil during pregnancy had a marked adverse effect on newborn survival at day 2, leading to much greater odds of mortality than in the control (odds ratio 8.26) and unoxidized fish oil (odds ratio 13.70) groups. In addition, maternal intake of oxidized fish oil during pregnancy led to increased insulin resistance at the time of weaning (3 wks after exposure) compared with control dams (HOMA-IR 2.64 vs. 1.42; P = 0.044). These data show that the consumption of oxidized fish oil is harmful in rat pregnancy, with deleterious effects in both mothers and offspring.
