RESUMEN

BACKGROUND: Catch-up growth issues among children born small for gestational age (SGA) present a substantial public health challenge. Prenatal exposure to heavy metals can cause adverse effects on birth weight. However, comprehensive studies on the accurate assessment of individual blood concentrations of heavy metals and their effect on the failure to achieve catch-up growth remain unavailable. This study aimed to evaluate the effects of uterine exposure to toxic metals cadmium, lead, and mercury and essential trace metals manganese and selenium at low concentrations on the postnatal growth of children born SGA. METHODS: Data on newborn birth size and other factors were obtained from the medical record transcripts and self-administered questionnaires of participants in the Japan Environment and Children's Study. The blood concentrations of lead, cadmium, mercury, selenium, and manganese in pregnant women in their second or third trimester were determined by inductively coupled plasma mass spectrometry. These heavy metal concentrations were also assessed in pregnant women's cord blood. Furthermore, the relationship between each heavy metal and height measure/catch-up growth in SGA children aged 4 years was analyzed using linear and logistic regression methods. These models were adjusted for confounders. RESULTS: We studied 4683 mother-child pairings from 103,060 pregnancies included in the Japan Environment and Children's Study. Of these, 278 pairs were also analyzed using cord blood. At 3 and 4 years old, 10.7% and 9.0% of children who were born below the 10th percentile of body weight had height standard deviation scores (SDSs) below 2, respectively. Cord blood cadmium concentrations were associated with the inability to catch up in growth by 3 or 4 years old and the height SDS at 3 years old. In maternal blood, only manganese was positively associated with the height SDS of SGA children aged 2 years; however, it was not significantly associated with catch-up growth in these children. CONCLUSION: Cadmium exposure is associated with failed catch-up development in SGA children. These new findings could help identify children highly at risk of failing to catch up in growth, and could motivate the elimination of heavy metal (especially cadmium) pollution to improve SGA children's growth.

RESUMEN

PURPOSE: Studies examining the associations between maternal social relationships and early childhood development have mainly focused on social relationships after childbirth. We aimed to prospectively examine the associations between the transition of maternal social isolation from the prenatal to postnatal period and early childhood development. METHODS: We analyzed data for 6692 mother-child pairs who participated in the Tohoku Medical Megabank Project Birth and Three-Generation Cohort Study. Social isolation in the prenatal and postnatal periods was assessed by the Lubben Social Network Scale-abbreviated version and categorized into four groups: none, prenatal only, postnatal only, and both. The Ages and Stages Questionnaire, Third Edition, which consists of five developmental areas, was used to assess developmental delays in children at 2 and 3.5 years of age. Multiple logistic regression analyses were conducted to examine the associations between maternal social isolation and developmental delays. RESULTS: The prevalence of social isolation in both the prenatal and postnatal periods was 13.1%. Social isolation in both the prenatal and postnatal periods was associated with developmental delays in children at 2 and 3.5 years of age: the multivariate-adjusted odds ratios (95% confidence intervals) were 1.68 (1.39-2.04) and 1.43 (1.17-1.76), respectively. Social isolation in the prenatal period only and social isolation in the postnatal period only were not associated with developmental delays in children at 2 and 3.5 years of age. CONCLUSION: Maternal social isolation in both the prenatal and postnatal periods was associated with an increased risk of developmental delays in early childhood.

RESUMEN

AIM: The aim of this study was to determine prenatal attachment and foetal health locus of control in pregnant women and factors affecting these parameters. METHODS: This cross-sectional study was conducted with 156 pregnant women (77 low-risk and 79 high-risk pregnancies). The study was carried out between August 2015 and February 2016. The data collection instruments included a Participant Information Form, the Prenatal Attachment Inventory and the Foetal Health Locus of Control Scale. RESULTS: Pregnant women's education and foetal health locus of control levels had positive and significant effects on prenatal attachment, and education had an effect on foetal health locus of control. Foetal health locus of control explained 6.3% of the total variance in prenatal attachment levels. CONCLUSION: As the educational statuses of pregnant women affected their prenatal attachment and foetal health locus of control, information, counselling and care should be prioritized for women with low education levels, in line with their needs. This is particularly important in terms of improving the control of pregnant women with lower prenatal attachment levels or internal locus of control over foetal health.

RESUMEN

AIM: This study aimed to analyse the psychological impact of the COVID-19 pandemic on pregnant women according to the pregnancy trimester, comparing their psychopathological symptomatology, pregnancy-specific stress, resilience and perceived stress to those of women pregnant before the pandemic. METHODS: A total of 797 pregnant women participated in the study, one group of 393 women pregnant before the pandemic and the other of 404 women pregnant during the pandemic. Student-t test was used to analyse continuous data and the Chi-square test was used for categorical data. RESULTS: Psychopathological symptomatology was significantly higher in six subscales of the SCL-90-R in pregnant women during COVID-19: somatisation, interpersonal sensitivity, depression, anxiety, phobic anxiety, obsessions-compulsions, mainly on the first two trimesters. There is also a higher level of pregnancy-specific stress in pregnant women during the pandemic on the first two trimesters, most likely due to the hypervigilance and fears related to the COVID-19 disease. Nevertheless, perceived stress, usually elevated during pregnancy, was lower in women pregnant during the pandemic in comparison to those pregnant before, as a positive consequence of being on lockdown and diminishing the exposure to daily stressful situations. CONCLUSIONS: Knowing the struggles these women go through during each trimester of pregnancy can be the key to a better health professional-patient relationship, consequently having a positive impact on their mental and physical health.

RESUMEN

This paper serves as a call to action for increased focus on emotion regulation during pregnancy. We make this case by summarizing the limited research to date on this topic, which has demonstrated that emotion regulation in pregnant people has important mental health, caregiving, and developmental correlates throughout the perinatal period. Given its crosscutting and modifiable nature, bolstering emotion regulation during pregnancy has the potential for considerable intergenerational consequences, and it is critical to further investigate this construct.

RESUMEN

Cannabis is still the most widely used illicit drug around the world. While its use has always been prevalent among adolescents, recent evidence suggests that its consumption is also increasing among other population groups, such as pregnant women and aged people. Given the known impact of cannabis on brain development and behavior, it is important to dissect the possible long-term impact of its use across different age groups, especially on measures of cognitive performance. Animal models of cannabinoid exposure have represented a fundamental tool to characterize the long-lasting consequences of cannabinoids on cognitive performance and helped to identify possible factors that could modulate cannabinoids effects in the long term, such as the age of exposure and doses administered. This scoping review was systematically conducted using PubMed and includes papers published from 2015 to December 2021 that examined the effects of cannabinoids, either natural or synthetic, on cognitive performance in animal models where exposure occurred in the prenatal period, during adolescence, or in older animals. Overall, available data clearly point to a crucial role of age in determining the long-term effect of cannabinoid on cognition, highlighting possible detrimental consequences during brain development (prenatal and adolescent exposure) and beneficial outcomes in old age. In contrast, despite the recent advances in the field, it appears difficult to clearly establish a possible role of dosage in the effects of cannabinoids on cognition, especially when the adolescent period is taken into account.

RESUMEN

AIM: This study was conducted to determine the experiences of women who encountered loss in the prenatal period. METHOD: This study was a qualitative study conducted using the phenomenological method and was conducted according to the guidelines of the COREQ checklist. A total of 11 women who were experienced loss in the early prenatal period were interviewed. The data were analyzed using the content analysis. RESULTS: Three main themes and eight sub-themes emerged. The themes were light of life (bubble of happiness, journey), dark farewell (silent scream inside, unfinished tale: motherhood, loneliness, family approach) and obscurity (uncertainty about the future, need for support). Women expressed that the loss process had negative effects on their mental health and that they needed help. CONCLUSION: Pregnancy illuminates women's lives, while prenatal loss involves intense and various negative emotions, and women need support in many ways. These results show that women who experienced loss in the prenatal period should be allowed to express their feelings, thoughts and experiences, and the risks in terms of mental health should be reduced by supporting them during the loss and mourning process.

RESUMEN

BACKGROUND: Six liner measurements of constant cranial cervical ganglion (CCG), three inconstant main, first, second middle cervical ganglia (MG, MG1, MG2), and interganglionic branch (IGB) were taken to determine normal foetal growth rates and patterns of cervical sympathetic trunk (CST) components in different gestational ages. MATERIALS AND METHODS: Forty sheep foetuses of both sexes aged from 60 to 140 days were divided into four groups and 80 sides of foetuses were examined under a stereomicroscope using a digital calliper. RESULTS: Following findings were obtained: 1) There was no significant difference for the values between sex and body side among all age groups, although sex and laterality differences in CST length and laterality differences in IGB total length and MG1 width were found regardless of age groups. 2) Correlations between dimensions of CST components and crown-rump length (CRL) were always positive during foetal period and decreased with increasing foetal age. 3) The highest growth rate in CST components in foetal sheep took place in the youngest age group because of rapid growth rates in lengths of IGB and CCG. CONCLUSIONS: Based on these detailed findings, comparative prenatal growth rates and patterns of animal organs and body, embryological and histological data as well as neurovertebral relationships among cervical parts of sympathetic trunk, spinal cord, and vertebral column were discussed and compared with previous studies. Although allometric growth of CST in relation to CRL was constant between foetal sheep and pig, there were specific characteristics in prenatal growth of CST components in foetal sheep which were different from those of foetal pig. It seems that only growth pattern in length of CST in sheep during foetal period follows the same growth pattern of CRL, body weight, and length of cervical parts of spinal cord and vertebral column.

RESUMEN

OBJECTIVE: To identify the temporal-spatial expression of B7 family co-inhibitory molecules during lung development, and to explore the roles of B7 family co-inhibitory molecules in the developmental process of pulmonary regional immunity. METHODS: The expression of B7 family co-inhibitory molecules (B7-1, B7-2, B7-H1, B7-DC) in different developmental stages of Rhesus monkey lungs were normalized and calculated by the reads per kilo-base of transcript per million mapped reads (RPKM) method. Immunohistochemical staining was performed to identify the localization and the protein of B7 family co-inhibitory molecules in different developmental phase (canalicular stage, cystic stage, alveolar stage) in mouse. RESULTS: The expression of B7 family co-inhibitory molecules in rhesus monkey were increased during the prenatal period (cystic stage, alveolar stage), the expressions of B7-2 and B7-H1 mRNA were significantly increased in alveolar stage (P<0.05). The results of immuno-histochemistry indicated that B7 family co-inhibitory molecules were mainly expressed in airway epithelial cells, and their protein levels were increased during the prenatal period. The expressions of B7-2, B7-H1 and B7-DC were significantly increased from canalicular stage (P<0.05). The protein of B7-2 was higher in airway than that in bronchus (P<0.05). CONCLUSIONS: B7 family co-inhibitory molecules are mainly expressed in airway epithelial cells, and the expressions are increased during the prenatal period, which suggests that B7 family co-inhibitory molecules are involved possibly in the development of pulmonary regional immunity.

RESUMEN

AIMS/HYPOTHESIS: Limited studies have compared the effect of prenatal or postnatal exposure to different severities of famine on the risk of developing diabetes. We aimed to measure the association between diabetes in adulthood and the exposure to different degrees of famine early in life (during the prenatal or postnatal period) during China's Great Famine (1959-1962). METHODS: Data from 3967 individuals were included (a total of 2115 individuals from areas severely affected by famine, 1858 from moderately affected areas, 6 excluded due to missing data). A total of 2335 famine-exposed individuals were further divided into those exposed during the fetal stage, childhood or adolescence/young adulthood. We constructed a difference-in-differences model to compare HbA1c and fasting plasma glucose among the participants exposed to different degrees of famine intensity at different life stages. Logistic analyses were used as measures of the association between diabetes and the different levels of famine severity at different life stages. RESULTS: Individuals who had been exposed to famine during the fetal period, childhood, and adolescence/adulthood and who had lived in a severely affected area had a 0.31%, 0.20% and 0.27% higher HbA1c, respectively, (all p < 0.01) compared with unexposed individuals. After adjusting for age, sex, smoking status, education level and waist circumference, participants exposed to severe famine during the fetal stage (OR 1.90, 95% CI 1.12, 3.21) and childhood (OR 1.44, 95% CI 1.06, 1.97) had significantly higher odds estimates. Unexposed participants living in severely and moderately affected areas had a comparable prevalence of diabetes (OR 1.22, 95% CI 0.80, 1.87). A significant interaction between famine exposure during the fetal and childhood periods and the level of severity in the area of exposure was found (p < 0.05). CONCLUSIONS/INTERPRETATION: Exposure to severe famine in the fetal or childhood period may predict a higher HbA1c and an increased diabetes risk in adulthood. These results from China indicate that both the prenatal and postnatal period may offer critical time windows for the determination of the risk of diabetes.

RESUMEN

Studies on the impact of micronutrient levels during different pregnancy periods on child psychomotor functions are limited. The aim of this study was to evaluate the association between maternal plasma concentrations of selected micronutrients, such as: copper (Cu), zinc (Zn), selenium (Se), and child neuropsychological development. The study population consisted of 539 mother-child pairs from Polish Mother and Child Cohort (REPRO_PL). The micronutrient levels were measured in each trimester of pregnancy, at delivery and in the cord blood. Psychomotor development was assessed in children at the age of 1 and 2 years using the Bayley Scales of Infant and Toddler Development. The mean plasma Zn, Cu and Se concentrations in the 1st trimester of pregnancy were 0.91±0.27mg/l, 1.98±0.57mg/l and 48.35±10.54µg/l, respectively. There were no statistically significant associations between Cu levels and any of the analyzed domains of child development. A positive association was observed between Se level in the 1st trimester of pregnancy and child language and motor skills (ß=0.18, p=0.03 and ß=0.25, p=0.005, respectively) at one year of age. Motor score among one-year-old children decreased along with increasing Zn levels in the 1st trimester of pregnancy and in the cord blood (ß=-12.07, p=0.003 and ß=-6.51, p=0.03, respectively). A similar pattern was observed for the association between Zn level in the 1st trimester of pregnancy and language abilities at one year of age (ß=-7.37, p=0.05). Prenatal Zn and Se status was associated with lower and higher child psychomotor abilities, respectively, within the first year of life. Further epidemiological and preclinical studies are necessary to confirm the associations between micronutrient levels and child development as well as to elucidate the underlying mechanisms of their effects.

RESUMEN

Estrogen's role in allergic diseases has recently been of considerable interest. The present article seeks to determine the relationship between estrogen-dependent traits and allergic rhinitis. The following traits were considered: digit ratio, age at menarche, regularity of menstrual cycles, and the waist to hip ratio. The study consisted of surveys and measurement data collected from 768 female university undergraduates. One hundred and sixty eight undergraduates (21.9%) had been diagnosed with allergic rhinitis. The results of logistic regression show that in women with a high digit ratio, indicating exposure to a higher estrogen level in the prenatal period, the risk of allergic rhinitis was almost twice as high as that in those with an average value of the ratio. The difference in the digit ratio was greater for the right than left hand. A significantly higher risk of allergic rhinitis was also observed in women who experienced first menstruation at a younger age. No differences in risk of allergic rhinitis were noted due to general obesity, abdominal obesity, or irregularity of menstrual cycles. We conclude that a higher digit ratio is suggestive of a propensity to allergies in adulthood plausibly having to do with greater exposure to estrogen at early stages of ontogenetic development.

RESUMEN

Ethinylestradiol (EE) is an endocrine disruptor (ED) which acts as an oestrogen agonist; this compound is known as an oral contraceptive. Male and female rodents exposed to EE during critical time points of development, such as in the prenatal period, show alterations in their reproductive tract during adulthood. Few studies have placed an emphasis on the effects of EE during ageing. Thus, this study had as it's objective the analysis of the morphological and immunohistochemical effects of exposure to EE in the prenatal period on ventral male prostate and female prostate of gerbils (Meriones unguiculatus) during ageing. The animals were exposed to EE (15 µg/kg/day) during the 18-22th days of prenatal life (EE/PRE group), and the analyses were performed when the male and female reached 12 months of age. Our results showed an increase in the development of prostatic intraepithelial neoplasia (PIN), which was observed in the male and female prostate of EE/PRE groups. Immunohistochemistry showed a rise in prostatic epithelial and basal cells immunoreactivity, respectively, and to AR and p63 in the male EE/PRE. There were alterations in the morphological pattern of the prostatic glands and increase in predisposition to emergence of prostatic lesions of both sexes during ageing. Despite male and female having been exposed to the same doses of EE, the "exposure to EE promoted modifications" more accentuated in the male prostate. Thus the male gland is more sensitive to the action of this synthetic oestrogen than the female prostate.

RESUMEN

Background: Paternal prenatal depression affects not only the fathers but also their spouses and children's future lives. Many socioeconomic and cultural factors affect the probability of paternal depression. Little is known about the prevalence of and factors associated with paternal prenatal depression in the Middle East. Aim: To estimate the prevalence of paternal prenatal depression among fathers visiting a tertiary university hospital, as well as to determine the factors associated with paternal prenatal depression within study participants. Methods: This analytical cross-sectional study included 442 fathers whose wives were pregnant and were undergoing regular assessments at antenatal clinics in a tertiary university hospital in Riyadh, Saudi Arabia. The Edinburgh Postnatal Depression Scale (EPDS) was used to assess paternal depression. Bivariate and multivariate analyses were performed. Results: The prevalence of paternal prenatal depression was 26.9%. It was correlated with smoking (odds ratio (OR)=1.8, p=0.006), maternal depression (OR=4.59, p<0.001), and experiencing isolation (OR=5.34, p<0.001). The odds of paternal prenatal depression decreased with social support from friends and family (OR=0.227 and 0.133, respectively) and p<0.001. Discussion and Conclusion: Paternal prenatal depression was prevalent within the study participants. Notably, experiences of isolation and maternal depression emerged as prominent factors that were significantly associated with the manifestation of paternal depression. Consequently, it becomes imperative to implement systematic depression screenings for expectant fathers and to meticulously consider the array of the factors associated with paternal depression.

RESUMEN

Objective: To investigate the relationship between maternal folic acid (FA) supplementation during the pre-conceptional and prenatal periods and the subsequent risk of autism spectrum disorder (ASD) in offspring. Methods: A total of 6,049 toddlers aged 16-30 months were recruited from August 2016 to March 2017 for this cross-sectional study conducted in China. The parents of the enrolled toddlers provided information on maternal supplemental FA, socio-demographic information, and related covariates. Standard diagnostic procedures were implemented to identify toddlers with ASD. Results: Among the 6,049 children included in the study, consisting of 3,364 boys with an average age of 22.7 ± 4.1 months, a total of 71 children (1.2%) were diagnosed with ASD. Mothers who did not consume FA supplements during the prenatal period were found to have a significantly increased risk of having offspring with ASD, in comparison to those who were exposed to FA supplements (odds ratio [OR] = 2.47). However, we did not find a similar association during the pre-conceptional period. Compared to mothers who consistently used FA supplements from pre-conception to the prenatal period, those who never used FA supplements were statistically significantly associated with a higher risk of ASD in their offspring (OR = 2.88). Conclusion: This study indicated that providing continuous maternal FA supplementation during the pre-conceptional and prenatal periods may decrease the risk of ASD in offspring. The prenatal period is considered to be the most crucial time for intervention.

RESUMEN

PURPOSE: Investigate associations of maternal social experiences with offspring epigenetic age acceleration (EAA) from birth through mid-childhood among 205 mother-offspring dyads of minoritized racial and ethnic groups. METHODS: We used linear regression to examine associations of maternal experiences of racial bias or discrimination (0 = none, 1-2 = intermediate, or 3+ = high), social support (tertile 1 = low, 2 = intermediate, 3 = high), and socioeconomic status index (tertile 1 = low, 2 = intermediate, 3 = high) during the prenatal period with offspring EAA according to Horvath's Pan-Tissue, Horvath's Skin and Blood, and Intrinsic EAA clocks at birth, 3 years, and 7 years. RESULTS: In comparison to children of women who did not experience any racial bias or discrimination, those whose mothers reported highest levels of racial bias or discrimination had lower Pan-Tissue clock EAA in early (-0.50 years; 90% CI: -0.91, -0.09) and mid-childhood (-0.75 years; -1.41, -0.08). We observed similar associations for the Skin and Blood clock and Intrinsic EAA. Maternal experiences of discrimination were not associated with Pan-Tissue EAA at birth. Neither maternal social support nor socioeconomic status predicted offspring EAA. CONCLUSIONS: Children whose mothers experienced higher racial bias or discrimination exhibited slower EAA. Future studies are warranted to confirm these findings and establish associations of early-life EAA with long-term health outcomes.

RESUMEN

Introduction: Prenatal period is the key time in human development. Many prenatal factors are well-known and increase the risk of developing diseases' after birth. Few studies indicated the link between the prenatal period and the prevalence of migraine in childhood and adolescence so far. We decided to broaden current knowledge and investigate whether the prenatal factors influence the prevalence of migraine in adulthood. The objective of this study is to provide evidence of relationship between in utero environment and risk of migraine. Methods: In total 266 females (136 in the migraine group, 130 in the control group) and 80 males (35 in the migraine group, 45 in the control group), aged 18-65 participated in the study. The quality of prenatal environment was characterized on the basis of mother's and father's education, tobacco smoke exposure, alcohol consumption, and traumatic event during pregnancy, which are considered as prenatal factors and affect on fetal development. Results: Migraine occurrence in adulthood was significantly associated with maternal tobacco smoking during pregnancy (OR 3.42, 95% CI 1.54-7.61, p = 0.036) and traumatic event during pregnancy (OR 2.27, 95% CI 1.24-4.13, p = 0.020). Discussion: Our study suggests that the fetal programming effect of tobacco smoking exposure and maternal trauma is not limited to prenatal life and is suggested as having a role in adulthood. Our findings support evidence that migraine adulthood can be partly influenced by early life conditions.

RESUMEN

Radon is a carcinogenic factor, but the effects of the potential carcinogenicity of radon progeny on the human body during the prenatal period have not yet been explored. Based on data regarding the half-lives of radon-222 and radon-220 and their progeny, this paper considers their potential effects on the human body in the prenatal period. Radon-220 represents a small fraction of the total radon concentration in the air, but the dose of radon-220 progeny may have a significant effect in the prenatal period, as the precursors of polonium-212 exhibit substantially longer half-lives than the corresponding precursors of polonium-214. Theoretically, it is possible that radon-220 decay products, particularly polonium-212, are the predominant emitters of alpha particles in the prenatal period. Studies aiming to establish a relationship between exposure to radon during pregnancy and the subsequently observed incidence of childhood neoplasms should consider this observation.

RESUMEN

Posterior reversible encephalopathy syndrome (PRES) is a clinical imaging syndrome characterized by vasogenic edema in the posterior cerebral circulation, with severe preeclampsia (PE) and eclampsia as major etiologies. Posterior reversible encephalopathy syndrome lesions are often reversible, but they can be potentially fatal in obstetric crises, causing serious complications such as cerebral hemorrhage, confusion, headache, visual symptoms, and stroke if not treated immediately. Neurological sequelae and even death may occur in a minority of these cases. In this paper, we report the case of a 26-year-old primigravida at 25 weeks of gestation who was irregular with obstetric visits. The patient presented with edema, nausea and vomiting, dizziness, blurry vision, falling down, and a maximum blood pressure of 190/85 mmHg. A brain MRI revealed PRES. Approximately 10 hours after admission, intrauterine fetal death occurred. After treatment, the patient was in stable condition and successfully induced for delivery.

RESUMEN

Background: Generalized anxiety disorder is characterized by excessive and uncontrollable worry about a variety of events. It is critical to ensure a pregnant mother's mental health in order to reduce pregnancy and birth-related problems. The major goal of current study was to identify the factors associated with generalized anxiety disorder among mothers attending perinatal services in the study area during COVID-19 using ordinal logistic regression. Methods: The institution-based cross-sectional study was conducted from July 10th, 2020 to August 10th, 2020 at Kembata Tembaro zone, Southern Ethiopia. The current study included 423 mothers. The GAD-7 scale was used to assess the anxiety level among mothers. An Ordered logit model was used to identify the determinants of GAD. Brant test of the parallel line was utilized to check proportionality assumption. The statistical significance was determined using an adjusted proportional odd ratio with a 95%CI, and a p-value <5%. STATA software version 14 was used to analyze statistical data. Results: Of all 423 mothers attending perinatal service during COVID-19; 134(31.7%), 171(40.4%), 85(20.1%), and 33 (7.8%) had non/minimal to severe generalized anxiety disorder respectively. The results of multivariable proportional odds model (POM) showed that the variables town residents [aPOR = 1.827; 95% CI:1.233-2.708], having alcohol habit [aPOR = 3.437, 95% CI = 1.397-8.454], having occupation [aPOR = 0.509, 95% CI: 0.303-0.857], being health care worker [aPOR = 0.117, 95% CI = 0.044-0.311], having chronic illness [aPOR = 7.685, 95% CI = 3.045-19.39], having family history of anxiety/mood disorder [aPOR = 7.839, 95% CI = 2.656-23.12], fear of contracting COVID-19 [aPOR = 1.704, 95% CI = 1.152-2.521], having moderate social support [aPOR = 0.648, 95% CI = 0.425-0.989], having strong social support [aPOR = 0.495, 95% CI = 0.272-0.901] were significantly associated with generalized anxiety disorder at 5% level of significance. Conclusion: Current findings concluded that the prevalence of GAD among mothers attending perinatal service during COVID-19 was high. The covariates like being town resident, lower-income status, occupation status, having a chronic illness, having a positive family history of anxiety or mood disorder, perceived social support, and fear of the COVID-19 were significantly associated with generalized anxiety disorder among mothers. Mothers who visit perinatal services should be given special consideration to improve health care services and ensure their mental health.
