Abstract
PURPOSE Pruritus gravidarum is characterized by general pruritus in the absence of primary skin lesions. In this study, we sought to evaluate whether the offspring (≤ 18 years) of mothers diagnosed with pruritus gravidarum, are at increased risk of long-term dermatology-related hospitalization. METHODS A population-based, retrospective cohort study of all singleton deliveries between 1991 and 2021 was conducted at a tertiary medical center. Offspring of mothers diagnosed with pruritus gravidarum were compared to offspring of non-exposed mothers. First admission involving dermatological morbidity of the offspring were analyzed using ICD-9 codes. Kaplan-Meier survival curves were used to compare the cumulative hospitalization incidence between the groups and Cox regression models were utilized to adjust for confounding variables. RESULTS A total of 849 women out of 356,356 deliveries that fulfilled the inclusion criteria were diagnosed with pruritus gravidarum during pregnancy (0.23%). Among offspring to mothers with pruritus gravidarum versus non-pruritus gravidarum mothers, hospitalization rates involving dermatological morbidity, were higher (7.1% vs. 4.6%, p < .001) a finding that was consistent with the Kaplan-Meier survival curve (Log rank p = .002). In the Cox regression model, pruritus gravidarum was found to be a significant independent risk factor for dermatological-related hospitalizations in the offspring after controlling for gestational age, hypertensive disorders, diabetic disorders, meconium-stained amniotic fluid exposure and fertility treatments (adjusted HR = 1.44, 95% CI 1.12-1.85, p = .004). CONCLUSIONS Maternal pruritus gravidarum is an independent risk factor for long-term dermatology-related hospitalization in the offspring up to the age of 18 years.

Abstract
STUDY QUESTION Is the health of singletons born after frozen embryo transfer (FET) comparable to that of singletons born after fresh embryo transfer (ET) until early adulthood? SUMMARY ANSWER The health of singletons born after FET does not differ from that of singletons born after fresh ET. WHAT IS KNOWN ALREADY The differences in perinatal outcomes of children born after FET and fresh ET are well known. FET is associated with an increased risk of large-for-gestational-age but diminished risks of preterm birth (PTB), small-for-gestational-age and decreased perinatal mortality compared to fresh ET. However, knowledge on the long-term health after FET is scarce. STUDY DESIGN, SIZE, DURATION This retrospective register-based cohort study compares singletons born after FET (n = 1825) between the years 1995 and 2006 to those born after fresh ET (n = 2933) and natural conception (NC, n = 31 136) with a mean follow-up time of 18-20 years. PARTICIPANTS/MATERIALS, SETTING, METHODS Singletons born after FET were compared to those born after fresh ET and NC regarding the frequencies of diagnoses in the main ICD-10 chapters (International Statistical Classification of Diseases and Related Health Problems, 10th revision), the number of outpatient visits and hospital admissions, and mortality. Adjustments were made for PTB, maternal age, parity, socioeconomic status based on mother's occupation and offspring sex. The study combines data from the Finnish Medical Birth Register, the Finnish Care Register for Health Care (CRHC) and the Cause-of-Death Register at Statistics Finland. The Student's T-test was used for continuous variables, and the Chi-square test was used for categorical variables. Cox regression was used to estimate crude and adjusted hazard ratios (HRs and aHRs, respectively). A general linear model was used to compare the means of outpatient visits, hospital admissions and lengths of hospital stays per person. MAIN RESULTS AND THE ROLE OF CHANCE No significant differences between the FET and fresh ET groups were found in the frequency of diagnoses in any of the ICD-10 chapters or in the parameters describing the need for hospital care. However, compared to the NC group, higher proportions in the FET group had outpatient visits in the hospital (93.5% vs 92.2%, aHR 1.23, 95% CI 1.17, 1.30) or hospital admissions (48% vs 46.5%, aHR 1.28, 95% CI 1.19, 1.37). Compared to the NC group, the FET group had elevated adjusted risks of diagnoses of infectious and parasitic diseases (aHR 1.24; 95% CI 1.11, 1.38), neoplasms (aHR 1.68; 95% CI 1.48, 1.91), diseases of the eye and adnexa, the ear or mastoid process (aHR 1.11; 95% CI 1.01, 1.21), the respiratory system (aHR 1.15; 95% CI 1.06, 1.23), the digestive system (aHR 1.17; 95% CI 1.05, 1.32), the skin or subcutaneous tissue (aHR 1.28; 95% CI 1.14, 1.43) and the genitourinary system (aHR 1.27; 95% CI 1.11, 1.45), as well as congenital malformations or chromosomal abnormalities (aHR 1.31; 95% CI 1.14, 1.50) and symptoms, signs or abnormal clinical or laboratory findings (aHR 1.25, 95% CI 1.16, 1.34). LIMITATIONS, REASONS FOR CAUTION Only hospital-based inpatient and outpatient care is covered by the CRHC register, excluding milder cases diagnosed elsewhere. We were not able to study the effect of ART treatments and subfertility separately in our setting. In addition, although our cohort is reasonably sized, even larger cohorts would be needed to reliably study rare outcomes, such as cancer. WIDER IMPLICATIONS OF THE FINDINGS For many ICD-10 chapters, we present the first published data on the long-term outcome of singletons born after FET. The results on FET versus fresh ET are reassuring, whereas the results on FET versus NC warrant further investigation. STUDY FUNDING/COMPETING INTEREST(S) Finnish government research funding was obtained for this study. Funding was also obtained from the Finnish Medical Society Duodecim, the Päivikki and Sakari Sohlberg Foundation, Orion Research Foundation, Finnish Society of Obstetrics and Gynaecology (research grants to A.M.T.) and Finnish government research funding. The funding sources were not involved in the planning or execution of the study. The authors have no competing interests to declare. TRIAL REGISTRATION NUMBER N/A.

Abstract
BACKGROUND Currently, 1 in 25 children born in Australia are conceived through ARTs such as IVF and ICSI. Worldwide over 8 million children have been born after ART. There is evidence that these children are at an increased risk of congenital malformations, preterm birth, low birth weight and neonatal morbidity. However, studies on long-term health outcomes of offspring conceived after ART are lacking. Atopic disorders, such as asthma, atopic dermatitis and various allergies are increasingly common within society, and concerns have been raised that ART increases the risk of atopy amongst offspring. OBJECTIVE AND RATIONALE The aim of this study was to systematically summarise and quantify the risk of atopic disorders in offspring conceived with ART compared to those conceived without ART. SEARCH METHODS A systematic review was conducted according to the PRISMA guidelines. Several systematic searches were performed in the following international databases: Medline, Embase, Cinahl, PsychINFO, AMED, Global Health and ISI Web of Science. Search terms utilised were all terms pertaining to ART, IVF, ICSI, asthma, atopic dermatitis and allergies. The search period was 1978-2021. Included observational studies stated a primary outcome of asthma or allergies in offspring conceived after ART, with a comparison group conceived without ART. Individual studies were scored on quality and risk of bias, using the Newcastle-Ottawa scale (NOS). OUTCOMES There were 26 studies which met the inclusion criteria; of these, 24 studies investigated asthma in offspring conceived after ART. While 10 studies, including the two largest population-based studies, reported a significantly increased risk of asthma in offspring conceived after ART (adjusted odds ratio (aOR) range: 1.20-2.38), 14 smaller cohort studies found no difference (aOR range 0.70-1.27). In the meta-analysis of the 14 highest-quality studies (NOS ≥ 7), a modest yet significantly increased risk of asthma was demonstrated in offspring conceived after ART [risk ratio (RR) 1.28 (1.08-1.51)]. Although heterogeneity in these 14 studies was high (I2 = 85%), the removal of outliers and high weight studies significantly reduced heterogeneity (I2 = 0% and I2 = 34% respectively) while still demonstrating a significantly increased risk [RR 1.19 (1.10-1.28) and RR 1.31 (1.03-1.65), respectively]. The increased asthma risk was also observed in most subgroup and sensitivity analyses. The allergy rates were not increased in offspring conceived after ART in 9 of 12 studies (aOR range 0.60-1.30). In summary, the findings of this systematic review and meta-analysis suggest a trend towards a significantly increased risk of asthma, but not allergies, in offspring conceived after ART. There was no evidence of publication bias in the asthma studies and minimal evidence of publication bias in the allergy studies (both P > 0.05). WIDER IMPLICATIONS Asthma brings considerable burden to the quality of life of individuals and to society. Hence, it is of great importance to untangle potential causal pathways. Although ART use is common, knowledge about its long-term health effects is required to provide evidence-based advice to couples considering ART, and to be vigilant for any potential adverse health effects on offspring conceived after ART.

Abstract
OBJECTIVE Infectious diseases account for up to 43% of childhood hospitalizations. Given the magnitude of infection-related hospitalizations, we aimed to evaluate the effect of maternal smoking during pregnancy on the risk for long-term childhood infectious morbidity. STUDY DESIGN This is a population-based cohort analysis comparing the long-term risk for infectious diseases, in children born to mothers who smoked during pregnancy versus those who did not. Infectious diseases were predefined based on International Classification of Diseases, Ninth Revision codes. Deliveries occurred between the years 1991 and 2014. RESULTS A total of 246,854 newborns met the inclusion criteria; 2,986 (1.2%) were born to mothers who smoked during pregnancy. Offspring of smokers had significantly higher risk for several infectious diseases during childhood (upper respiratory tract, otitis, viral infections, and bronchitis) as well as increased risk for total infection-related hospitalizations (odds ratio = 1.5, 95% confidence interval [CI]: 1.3-1.7; p = 0.001). Cumulative incidence of infection-related hospitalizations was significantly higher in offspring of smokers (log-rank test, p = 0.001). Controlling for maternal age, diabetes, hypertensive disorders, and gestational age at index delivery, smoking remained an independent risk factor for infectious diseases during childhood (adjusted hazard ratio = 1.5, 95% CI: 1.3-1.6; p = 0.001). CONCLUSION Intrauterine exposure to maternal smoking may create an environment leading to an increased future risk for long-term pediatric infectious morbidity of the offspring.

Abstract
Recent evidence suggests that a long inter-pregnancy interval (IPI: time interval between live birth and estimated time of conception of subsequent pregnancy) poses a risk for adverse short-term perinatal outcome. We aimed to study the effect of short (<6 months) and long (>60 months) IPI on long-term cardiovascular morbidity of the offspring. A population-based cohort study was performed in which all singleton live births in parturients with at least one previous birth were included. Hospitalizations of the offspring up to the age of 18 years involving cardiovascular diseases and according to IPI length were evaluated. Intermediate interval, between 6 and 60 months, was considered the reference. Kaplan-Meier survival curves were used to compare the cumulative morbidity incidence between the groups. Cox proportional hazards model was used to control for confounders. During the study period, 161,793 deliveries met the inclusion criteria. Of them, 14.1% (n = 22,851) occurred in parturient following a short IPI, 78.6% (n = 127,146) following an intermediate IPI, and 7.3% (n = 11,796) following a long IPI. Total hospitalizations of the offspring, involving cardiovascular morbidity, were comparable between the groups. The Kaplan-Meier survival curves demonstrated similar cumulative incidences of cardiovascular morbidity in all groups. In a Cox proportional hazards model, short and long IPI did not appear as independent risk factors for later pediatric cardiovascular morbidity of the offspring (adjusted HR 0.97, 95% CI 0.80-1.18; adjusted HR 1.01, 95% CI 0.83-1.37, for short and long IPI, respectively). In our population, extreme IPIs do not appear to impact long-term cardiovascular hospitalizations of offspring.

Abstract
In this study, we investigate if children born following assisted reproduction technologies (ARTs) are at an increased risk for long-term ophthalmic complications. For this purpose, a population-based cohort analysis was conducted which included all deliveries between 1991 and 2014 at a single tertiary medical center. Offspring were classified relative to conception method as ART or spontaneous pregnancies. Offspring hospitalizations up to the age of 18 years involving ophthalmic morbidities were evaluated according to a predefined set of ICD-9 codes. A Kaplan-Meier survival curve was used to compare cumulative hospitalization rates in exposed (ART) and unexposed offspring (spontaneous), and a Cox proportional hazards model was used to control for potential confounders. A total of 243,682 deliveries were included in the study. In that, 1.8% of the deliveries (4364) were of mothers who underwent fertility treatments and 98.2% (239,318) were conceived spontaneously. Offspring born to mothers who underwent fertility treatments had a significantly higher hospitalization rate involving ophthalmic morbidity, as compared to spontaneously conceived offspring (1.2% vs. 1.0%, p = 0.04). The Kaplan-Meier survival curve pointed to a significantly higher cumulative incidence of ophthalmic morbidity following ART (log rank p = 0.02). Cox proportional hazards model was adjusted for maternal age, preterm delivery, maternal hypertensive disorders, diabetes, and mode of delivery which demonstrated ART as an independent risk factor for long-term pediatric ophthalmic morbidity (adjusted hazard ratio = 1.37, CI 1.04-1.80, p-value = 0.02). We concluded that ART is an independent risk factor for long-term ophthalmic morbidity of the offspring.

Abstract
Drug allergy is associated with adverse short-term perinatal outcomes such as caesarian delivery and preterm delivery. The aim of the present study was to determine whether being born to a mother with known drug allergy increases the risk for long-term dermatological morbidity of the offspring. A population-based cohort study, comparing long-term dermatological morbidity of offspring to mothers with and without known drug allergy, was conducted. Dermatological morbidity was assessed up to the age of 18 years according to a predefined set of ICD-9 codes associated with hospitalization of the offspring. A Kaplan-Meier survival curve was used to compare cumulative incidence of long-term dermatological morbidity, and a Cox proportional hazards model was constructed to control of confounders. During the study period, 243,682 deliveries met the inclusion criteria, of them 4% (n = 9756) were of mothers with known drug allergy. Offspring born to mothers with known drug allergy had higher rates of long-term dermatological morbidity Likewise, the cumulative incidence of long-term dermatological morbidity was higher as compared with those without known drug allergy (Kaplan-Meier log-rank P = .021). Using a Cox proportional hazards model, controlling for confounders, being born to a mother with known drug allergy was found to be an independent risk factor for long-term dermatological morbidity of the offspring (adjusted HR 1.2, 95% CI 1.03-1.33, P = .016). Being born to a mother with known drug allergy is independently associated with higher risk for long-term dermatological morbidity of the offspring.

Abstract
BACKGROUND Despite the endocrine basis of several infertility etiologies, data on long-term endocrine consequences in offspring conceived following fertility treatments remain limited. AIM To determine the risk of long-term endocrine disorders among children born after in-vitro fertilization (IVF) and ovulation induction (OI) as compared with spontaneous pregnancies. STUDY DESIGN, SUBJECTS, AND OUTCOME MEASURES A population-based cohort study including all singleton deliveries occurring between 1991 and 2014 at a single tertiary medical center was performed. Hospitalization rates up to the age of 18 years involving endocrine disorders were compared between children delivered following pregnancies achieved by IVF, OI, and spontaneous pregnancies. A Kaplan-Meier survival curve was used to compare cumulative morbidity incidence. A Cox regression model was used to control for confounders. RESULTS During the study period, 242,187 singleton deliveries met the inclusion criteria; 1.0% were following IVF (n = 2603), 0.7% following OI (n = 1721), and the remaining (n = 237,863) were following spontaneous conceptions. Hospitalizations up to the age of 18 years involving endocrine disorders were comparable in children delivered following IVF (0.4%), OI (0.8%) and spontaneous pregnancies (0.5%; p = 0.09). The Kaplan-Meier survival curve demonstrated comparable cumulative incidence of endocrine morbidity following IVF and OI (log-rank p = 0.30). Using the Cox regression model while controlling for confounders, no significant association was noted between IVF (adjusted HR = 0.95, CI 0.51-1.87), or OI (adjusted HR = 1.32, CI 0.78-2.24) conceived pregnancies, and long-term pediatric endocrine morbidity. CONCLUSIONS Singletons conceived via fertility treatment do not appear to be at an increased risk for long-term endocrine disorders.

Abstract
Several studies have reported that health problems occur in assisted reproductive technology (ART)-conceived offspring. Recently, investigations have demonstrated that paternal environmental conditions influence offspring health. However, it is unclear whether the factors that cause male infertility per se affect offspring health and contribute to health problems in ART-born children. Scrotal heat stress represents a common cause for oligoasthenozoospermia, and in these cases, in vitro fertilization-embryo transfer (IVF-ET) is typically recommended for those individuals trying to conceive. We exposed C57BL/6J male mice to frequent and mild scrotal heat stress (fmSHS) (39°C for 30 min once weekly for 5 consecutive wk). Sperm was subjected to IVF-ET with oocytes of untreated C57BL/6J females to produce offspring mice. Glucose intolerance and insulin resistance was observed in the male offspring mice derived from fmSHS-exposed fathers. Islets, after evaluation, remained unchanged. Genes involved in glucose metabolism, especially, those in insulin signaling pathways, showed dysregulation in the liver of the fmSHS-derived male offspring. Differentially methylated regions were found in the sperm of fmSHS-exposed mice by whole genome bisulfite sequencing. Interestingly, abnormal methylation of some genes with altered expression in offspring was observed in both the sperm of fmSHS fathers and the liver of their male offspring. Our results suggest that the factors that cause male infertility can affect male offspring health by an epigenetic mechanism.

Abstract
OBJECTIVE Exploring the effect of maternal obesity during pregnancy on the long-term health of offspring is of great importance. The aim of this study was to evaluate the association between maternal pre-pregnancy obesity and future risk of childhood malignancies. STUDY DESIGN A population-based cohort analysis comparing the risk for long-term childhood malignancies (up to the age of 18 years) in children born (1991-2014) to mothers with and without pre-pregnancy obesity (body mass index > 30) was conducted in July 2017. Childhood malignancies were predefined based on ICD-9 codes, as recorded in the hospital medical files. Children with congenital malformations and multiple gestations were excluded from the analysis. The Kaplan-Meier survival curve was constructed to compare cumulative oncological morbidity in both groups over time. The Cox proportional hazards model was used to control for confounders. RESULTS During the study period, 241 273 infants met the inclusion criteria; 3268 were born to mothers with pre-pregnancy obesity. Children of obese women had significantly increased risk for several childhood malignancies (including brain tumors) as well as increased risk for total hospitalizations with malignancy diagnoses, even after controlling for several confounders (adjusted HR 1.90, 95% CI 1.07-3.37, P = 0.028). Cumulative incidence of oncological morbidity was also significantly increased over time in the studied group (log-rank P = 0.023). CONCLUSION Maternal pre-pregnancy obesity is significantly associated with an increased long-term risk for general childhood malignancies, and specifically brain tumors in the offspring. These results are important when counseling mothers regarding potential future risks and recommended lifestyle modifications.

Abstract
BACKGROUND Prevalence of pregnancies conceived following fertility treatments is high worldwide. While the impact of fertility treatments on short-term perinatal outcome is well established, long-term consequences are yet to be determined. OBJECTIVE To study the association between mode of conception and long-term gastrointestinal morbidity among children born following fertility treatments. STUDY DESIGN A population-based cohort analysis including all singleton deliveries occurring between 1991 and 2014 at a single regional tertiary medical center was performed. Fetuses with congenital malformations were excluded. A comparison was performed between children delivered following IVF, OI and spontaneous pregnancies. Hospitalizations up to the age of 18 years involving gastrointestinal morbidity were evaluated. Kaplan-Meier survival curve was used to compare cumulative morbidity incidence. A Cox regression model was used to control for confounders. RESULTS During the study period 242,187 singleton deliveries met the inclusion criteria; 1.1% following IVF (n = 2603), and 0.7% following OI (n = 1721). Hospitalization rates involving gastrointestinal morbidity were significantly higher in children conceived following IVF and OI (5.7%, 7.1% respectively) as compared with children conceived spontaneously (5.4%; p = 0.005). The Kaplan-Meier survival curve demonstrated a significantly higher cumulative incidence of gastrointestinal morbidity following IVF and OI (log rank p = 0.001). Using a Cox proportional hazards model, controlling for maternal age, preterm delivery, birthweight, maternal diabetes and hypertensive disorders in pregnancy, IVF (adjusted HR = 1.27, CI 1.08-1.50, p = 0.004), was noted as an independent risk factor for long-term pediatric gastrointestinal morbidity. CONCLUSION Singletons conceived by IVF appear to be at an increased risk for long-term gastrointestinal morbidity.

Abstract
ZusammenfassungDer Begriff Leiden ist in der Medizin und in der Bioethik bisher kaum reflektiert und dahingehend in normativer Hinsicht wenig bestimmt. Dennoch bildet das Leiden an einer Unfruchtbarkeit den Ausgangspunkt für die medizintechnischen Interventionen der assistierten reproduktionsmedizinischen Behandlung. Dabei wird implizit angenommen, dass der unerfüllte Kinderwunsch ein Leiden ist. Ob der unerfüllte Kinderwunsch allerdings ein Leiden darstellt, ist bisher nicht eindeutig geklärt worden.Ziel dieses Beitrages ist es, die Annahme, dass es sich beim unerfüllten Kinderwunsch um ein Leiden handelt, zu überprüfen. Anhand der Darstellung einiger gängiger Leidenskonzeptionen werden Merkmale von Leiden herausgearbeitet, die als treffende Grundannahmen für eine Leidensbestimmung gelten können. Es wird sich zeigen, dass der unerfüllte Kinderwunsch, entsprechend der Leidenskonzeptionen, als ein Leiden angesehen werden sollte, und ihm somit ein normativer Stellenwert zukommt. In einem weiteren Schritt ist zu klären, ob das Leiden an einem unerfüllten Kinderwunsch als ein Rechtfertigungsgrund für reproduktionsmedizinische Interventionen gelten kann. Dafür wird zum einen der Stellenwert von Leiden, als eine anthropologische Grundbedingung, im Zusammenhang mit dem Leidenslinderungsauftrag der Medizin diskutiert. Zum anderen werden die Risiken der reproduktionsmedizinischen Therapien sowie deren Bedeutung als Gesundheitsressourcen erörtert. Dabei wird deutlich, dass Leiden an einem unerfüllten Kinderwunsch immer ein psychosomatischer Komplex ist. Nur unter Berücksichtigung der psychoexistenziellen Dimension des Leidens ergibt sich eine Legitimation für eine angemessene somatische Intervention.

Abstract
OBJECTIVE While the impact of fertility treatments on the perinatal outcome is well established, the long-term effects on offspring are yet to be determined. The current study aimed to investigate the risk of long-term obstructive sleep apnea (OSA) among children born following in vitro fertilization (IVF) and ovulation induction (OI) as compared with spontaneously conceived pregnancies. STUDY DESIGN A retrospective population-based cohort study was performed. Exposure was defined as delivery following pregnancies conceived by IVF or OI. Incidence of OSA related hospitalizations of the offspring, up to the age of 18 years, was evaluated. A Kaplan-Meier survival curve and multivariable Cox regression models were used to assess the association. RESULTS During the study period, 242 187 singleton deliveries met the inclusion criteria; 1.1% were conceived following IVF (n = 2603), and 0.7% following OI (n = 1721). Offspring hospitalization rates, involving OSA (n = 1607), were higher among children conceived following IVF and OI pregnancies as compared with the rate in children conceived spontaneously (1.4% vs 1.2% vs 0.7%, respectively; P < .001). The Kaplan-Meier survival curve demonstrated a significantly higher cumulative incidence of OSA related hospitalizations following IVF and OI (log-rank P < .001). Using multiple Cox regression models, controlled for gestational age, maternal age, maternal smoking, maternal obesity, birthweight, offspring gender and obesity, IVF as well as OI exhibited a significant and independent association with pediatric OSA in all models with adjusted hazard ratios of 2.25, (95% confidence interval [CI] = 1.6-3.1) and 1.63 (95% CI = 1.1-2.5), respectively. CONCLUSION Both IVF and OI treatments appear to be independently associated with OSA in the offspring.

Abstract
OBJECTIVE The aim of this study was to evaluate the association between maternal smoking during pregnancy and future risk of childhood neoplasm risk. STUDY DESIGN A population based cohort analysis comparing the risk for long-term childhood neoplasms in children born (1991-2014) to mothers that smoked during pregnancy vs. those that did not. Childhood neoplasms were pre-defined based on ICD-9 codes, as recorded in the hospital medical files. Children with congenital malformations and multiple gestations were excluded from the analysis. Kaplan-Meier survival curves were constructed to compare cumulative oncological morbidity over time. Cox proportional hazards model was used to control for confounders. RESULTS 241,273 infants met the inclusion criteria; out of those 2841 were born to mothers that smoked during pregnancy. Offspring to smoking mothers had higher incidence of benign (OR 1.6, 95%CI 1.02-2.58; p value = .038) but not malignant tumors. Total cumulative neoplasm incidence was significantly higher in smoking women (Log Rank = 0.001) but no significant difference in the incidence of malignant tumors was noted (Log Rank = 0.834). In a Cox regression model controlling for maternal confounders; a history of maternal smoking during pregnancy remained independently associated only with increased risk for benign tumors (adjusted HR 2.5, 95%CI 1.57-3.83, p = .001). CONCLUSION Maternal smoking during pregnancy is associated with increased long-term risk for benign but not malignant tumors. This is important when counseling mothers regarding potential future risks and recommended lifestyle modifications. Despite this large population study with long follow-up, childhood malignancies are rare, and clarifying the possible association may require further studies.
