Infertility treatment and offspring blood pressure-a systematic review and meta-analysis
Studies have inconsistently observed that children conceived by IVF or ICSI have higher blood pressure compared to children not conceived by these ARTs.

| description | Studies have inconsistently observed that children conceived by IVF or ICSI have higher blood pressure compared to children not conceived by these ARTs.
The aim was to perform a systematic review and meta-analysis of blood pressure measures of offspring conceived by ART and those conceived naturally. Resolving the suspicion of ART as a risk factor of higher blood pressure, and therefore of heart disease, has public health and clinical implications.
A biomedical librarian searched the Embase, PubMed, and Web of Science databases. Searches were limited to records published in English since 1978. Grey literature was searched. Inclusion criteria were humans born via infertility treatment (vs no treatment) who underwent a blood pressure assessment. Exclusion criteria were non-human participants, non-quantitative studies, absence of a control group, and specialty populations (e.g. cancer patients only). Two reviewers independently screened each record's title and abstract and full text using Covidence, extracted data using Excel, and assessed bias using the National Heart, Lung, and Blood Institute's Quality Assessment Tool for cohort studies.
Of 5082 records identified, 79 were included in the systematic review and 36 were included in the meta-analysis of systolic blood pressure (SBP) and diastolic blood pressure (DBP) in ART and non-ART groups. Overall, 34 reports including 40 effect sizes from 25 unique cohorts, compared blood pressure between ART (N = 5229) and non-ART (N = 8509, reference) groups with no covariate adjustment. No standardized mean differences (SMD) in SBP (0.06 per SD of mmHg, 95% CI = -0.05, 0.18) or DBP (0.11, 95% CI = -0.04, 0.25) by treatment were found, but the heterogeneity was considerable (I2=76% for SBP and 87% for DBP). Adjusted analyses were presented in 12 reports, representing 28 effect sizes from 21 unique cohorts (N = 2242 treatment vs N = 37 590 non-treatment). Studies adjusted for varied covariates including maternal (e.g. age, education, body mass index, smoking, pregnancy complications), child (e.g. sex, age, physical activity, BMI, height), and birth characteristics (e.g. birth weight and gestational age). Adjusted results similarly showed no SMD for SBP (-0.03, 95% CI = -0.13, 0.08) or DBP (0.02, 95% CI = -0.12, 0.16), though heterogeneity remained high (I2 = 64% and 86%). Funnel plots indicated a slight publication bias, but the trim and fill approach suggested no missing studies. Removal of five studies which adjusted |

Funnel plots indicated a slight publication bias, but the trim and fill approach suggested no missing studies. Removal of five studies which adjusted for birth outcomes (potentially over-adjusting for mediators) made no material difference. Type of treatment (e.g. IVF vs ICSI), period effects by birth year (≤2000 vs >2000), offspring age group (<8, 8-14, 15+), or study location (e.g. Europe) did not modify the results.
In conclusion, conception by ART was not associated with offspring blood pressure in a meta-analysis, although considerable heterogeneity was observed. Given the increasing number of children born using ART, perpetuating a difference in blood pressure would mean unnecessary risk screening for many children/adults on a population level. At a clinical level, couples considering these reproductive technologies have some reassurance that there is no evidence of strong vascular 'programming' due to the techniques used.
