Introduction
Pregnancy is the most beautiful and memorable time in a woman’s life. It is accompanied with a lot of physical, social and psychological changes in a woman. During pregnancy and even after the birth of a child, women are at an increased risk of experiencing psychological problems. This duration is also a time when different types of mental health conditions that a woman may have previously experienced in the past can return or worsen.1 Anxiety, Mood Swings, and depression are among the common psychiatric problems that occur during pregnancy and in the year after childbirth. A pregnant woman’s emotions can affect her health that is her nutritional metabolic, psychological, hormonal and social conditions and can have a direct effect on fetal outcome and the pregnancy. A woman who has previously been suffering from psychiatric illness often does not have the will or the strength to adequately care for herself or her in-utero developing baby.2,3
Studies suggest during antenatal period, psychiatric symptoms not only affect woman’s health and her wellbeing but may also affect the neonate’s intra and extra uterine development There is emerging evidence in role of epi -genetics, as mediator highlighting the importance of long-term adaptation and programming through epigenetic mechanisms in response to environmental factors.4 Perinatal depression is defined as depression occurring in a woman while she is pregnant or within 12 months of delivery.5 The reported prevalence of postpartum depression in India ranges between 15.3% and 23.0% with an incidence of 11.0%. Around 14% of mothers continue to have symptoms of depression till up to 6 months after delivery. Economic and interpersonal relationship issues, partner violence, alcohol use by spouse and gender of the newborn child are among the major determinants of postpartum depression.6
Aim
Screening of antenatal women for risk of psychological problems during antenatal period and follow up of those women during postnatal period for risk assessment of Post Partum Depression.
Materials and Methods
Our study has a prospective longitudinal cohort design. Before initiating study permission was obtained from Institutional Ethics Committee. The study was carried out from November 2016 till Aug 2018. Initially 170 antenatal participants were recruited but 20 patients were excluded as they were lost to follow up. 150 Antenatal women were screened during their antenatal visit between 24 weeks up till 36weeks of pregnancy by semi structured questionnaire to screen high risk women. These women were then followed during Post Natal period between 4-8thday of postnatal period Edinburgh Post Natal Depression Scale(EDPS) was administered for risk assessment of Postnatal Depression. They were further followed between 4 to 8 weeks postnatal period using the EDPS.
A risk assessment questionnaire was utilized in local language after pre validation (crohn back alpha = 0.724) and was found to be reliable. The risk factors identified and included were socio demographic factors, education, place of residence, mother support while growing up, partner support, family Support, physical abuse, emotional abuse, History of mental illness, episode of depression lasting for more than 2 weeks, stress or loss in last 1 year.
EPDS is a commonly used 10-item self-reporting instrument, EPDS is a internationally validated questionnaires for detecting depression.6 We used the translated version of questionnaire.
All the antenatal women visiting the antenatal OPD of department of Obstetrics & Gynecology of People's College of Medical Sciences & Research Centre, Bhopal were explained the importance of screening of psychological problems. Those who agreed to participate were included after taking written informed consent. Those screened as high risk were referred to psychiatry consultation and counselor if required.
Result
150 women were included in the study who were screened as per the study protocol during once antenatal period and postnatal period twice.
Of all the 150 Antenatal women 47 women were screened as high risk (31 %) women. Rest 104 women (69%) were low risk for psychological diseases. (Figure 1)
20% had high EDPS scores (4-8 days) and 8.6% high risk at 4-8weeks. 23 women of 150 antenatal women were screened high risk by all the interventions during antenatal and postnatal period. The proportion of women screened positive were 15.3% (Figure 2)
Different Socio-Demographic profile of these identified high risk women were analyzed. (Table 1)
Age
Most of the antenatal participants in the study were of age group 23 to 28 years (46.7%) in both high risk and low risk group.15 % were in high risk and 31% were in low risk group Association between the age and high risk were found to be statistically non-significant. (X2 value-0.37, p value-0.82)
Education
Maximum number of participants had education between 6th and 10th Standard in both the groups. Association between low education and high risk was found to be statistically significant. (X2 value-10.24, p value-0.037) (Figure 3)
Parity
81.3% of cases were multigravida and rest were primigravidas. No statistical significant difference in risk was found between parity and risk difference between low and high risk groups (X2 value-2.12, p value-0.12).
Locality of residence (Urban /Rural)
In, 47 women who were high risk 60% (28/47) of the women were from rural background. The difference was found to be statistically significant (x2 4.6, P value -0.03). Residential location of participants was found to be statistical significant between the high and low risk groups. The rural antenatal women are found to be more at risk of psychological disorders.

Table 2
EPDS administered at 4 to 8 days of Post Natal Period
20% (30) had high scores of more than 10 rest 80% (120) had low risk scores.
EPDS administered at 4 to 8 weeks of Post Natal Period
8.6% (13) women had high scores 91.3% had low risk scores.
There is changes in scores after pregnancy which reveal that risk of depression reduces by 54 % at 4-8 days after pregnancy. Similarly, at 4-8wks interval risk of depression is further decreased by 57.6% as compared to antenatal time. These differences are significant as suggested by p values. (p<0.05) (Table 3)

Mode of delivery was found to be in positive correlation with risk of postnatal depression that as found to be statistically significant.(X2 – 38.21,p value -.001)
On follow up at 4-8 weeks 29.4% women delivered by cesarean were found to have high Edinburgh post natal depression score where as 70.6% women were now having low scores.
6.0% of women who delivered by vaginal route had high EDPS scores and 94.0% of women who delivered by vaginal route had low EDPS scores. Mode of delivery was found to statistical significant for postnatal depression at 4 -8 weeks.(x2 10.42, p value 0.008)
Association between antenatal risk factors and risk of post-depression 4-8 days after delivery
30.8%of the Cases with history of depression, stress for more than 2 weeks during pregnancy was found to be in positively associated with high risk for postnatal depression at 4 to 8 days which was statistically significant. (x2 5.8, p value 0.02)

Discussion
Ravi Prakash Upadhyay et al in 2017 have reported a systematic review and meta analysis on post partum depression in India.7 The estimated overall pooled prevalence was highest in the southern region of the country 26%; followed by eastern 23%; south-western 23%; 27 and western regions 21%. The northern region of India had the lowest prevalence 15%
The pooled prevalence was higher, for studies conducted in hospital settings 23%; than in community settings 17%. In urban versus rural areas 24% versus 17%. Prevalence was 20% and 21% when studies with mean maternal age of ≤ 25 years and > 25 years were pooled respectively A total of 32 studies reported risk factors for postpartum depression. The risk factors most commonly reported were financial difficulties (in 19 out of 21 studies that included this variable), domestic violence (6/8 studies), past history of psychiatric illness in the mother (8/11 studies), marital conflict (10/14 studies), lack of support from the husband (7/11 studies) and birth of a female baby (16/25 studies). Other commonly reported risk factors were lack of support from the family network (8/14 studies), recent stressful life event (6/11 studies), family history of psychiatric illness (7/13 studies), sick baby or death of the baby (6/13 studies) and substance abuse by the husband (4/9 studies). Preterm or low birth weight baby, high parity, low maternal education, current medical illness, complication in current pregnancy and unwanted or unplanned pregnancy and previous female child, were some of the other reported risk factors.
Bilal UR Rehman et al reported a study from a tertiary hospital of Srinagar.7 They reported in their study" the prevalence of depressive disorder as 26%. They also reported that "depression significantly increased with advancing pregnancy and advancing age, Socio-economic status, Women with bad relationship with in laws. The association between parity and depressive disorder was statistically insignificant"
Sujit D. Rathod et al reported "a study on Characteristics of perinatal depression in rural central, India.8 Which was conducted at Sehore District, Madhya Pradesh between 2013 and 2017. They identified 224 perinatal women from the Community Study and 130 perinatal women from the Facility Study, of whom 8.8% and 18.5% screened positive for depression, respectively. They emphasized that perinatal depression, must be utilized by policy-makers to prioritize mental health services for mothers along with maternal and child health services."
B. Sheeba reported a nested cohort study.9 The proportion of screened positive for prenatal depression was 35.7%. They reported that domestic violence was found to impose a five times higher and highly significant risk of developing prenatal depression among the respondents. Pregnancy related anxiety and a recent history of distressing events were also found to be a positive predictors of prenatal depression.
Veena A. Satyanarayana et al the review of literature on mental health during pregnancy and in the postpartum period and its influence on birth outcomes and child behavior.10 Their review suggested that the prevalence of antenatal depression and/or anxiety ranges from 8% to 30%. They reported in the review that "studies have also suggested a positive association between antenatal distress and birth outcomes and antenatal/postnatal distress on Maternal Fetal Attachment, temperament and cognitive–emotional and behavioral problems in the child. The impact of maternal mental health is also known to have lasting implications on child/adolescent behavior."
Shashi Rai et al reported The prevalence of depression, anxiety, and stress was found to be 25.5%, 63%, and 23%, respectively.11 They Pregnant females have increased biological vulnerability due to the hormonal maladjustment, psychological vulnerability due to apprehension for new life of motherhood, and social vulnerability due to the added demands of family support and care during this critical phase of her life
Avita Rose Johnson and colleagues reported 12 (5.8%) screened positive for antepartum mental morbidities, of which depression was the most common. 3.8% of all women screened positive for depression, with 15.4% showed depressive symptoms.12 They reported " Overall, 82 (39.4%) had the presence of one or more psychological symptoms, including fatigue, irritability, anxiety, and problems with sleep and concentration. Factors associated with the presence of antepartum mental illness included relationships with their spouse is poor, unsatisfactory relationship with siblings or in‑laws, and the desire to have a male child."
our study results mother had 1.3 times lesser risk, partner support had 4.4 times lesser risk, family support had 1.7 times lesser risk of having psychological problems during pregnancy.
Ashlesha Bagadia evidences of literature review suggest to integrate mental health with maternal health care.13 There is sufficient evidence to show that postpartum depression is a strong predictor of parenting stress, negatively impacting mother-infant bonding and leading to cognitive, emotional and behavioral problems in children. Antenatal mental health problems are also associated with poor nutrition, inadequate weight gain and irregular antenatal appointments. Children of mothers who have depression or anxiety are more susceptible to attention deficit hyperactivity disorder (ADHD), conduct disorders and emotional problems.
Vikram Patel found that maternal psychological morbidity was independently associated with low birth weight (odds ratio 1.44,95% CI 1.00- 2.07).14 They concluded that maternal psychological morbidity has an adverse impact on foetal growth. Our study also suggest similar adverse results on neonatal birth weight.
Samantha Meltzer-Brody explained the pathogenesis of perinatal depression15 "female reproductive steroid hormones -estrogen and progesterone in addition to reproductive function exhibits potent neuro-regulatory effects on a range of non reproductive behaviors including mood and cognition."
"In a normal HPA axis, the delivery of CRH from the paraventricular nucleus of the hypothalamus triggers the stimulation of adrenocorticotropic hormone (ACTH) from the anterior pituitary and, consequently, cortisol from the adrenal cortex. This hormonal system is regulated by negative feedback mediated by cortisol receptors in the anterior pituitary, hypothalamus, and hippocampus, as well as ACTH receptors in the anterior pituitary and CRH autoreceptors in the hypothalamus."
"In depressed patients A hallmark feature that characterizes the HPA axis in depression is the altered response to stress and inability to maintain regulation: indeed, hyperactivity of the HPA axis is one of the most robust biological findings in major depression."
"In the first few weeks postpartum, euthymic women demonstrate an HPA axis that remains refractory to external CRH challenge. In contrast, women with PPD have been shown to experience an ongoing blunting of ACTH response to corticotrophin-releasing hormone (CRH) at 6 to 12 weeks postpartum compared with non depressed women, interpreted as reflecting an ongoing hypo reactive HPA axis"
"There are specific sites where a methyl group can attach to DNA via cytosine through an enzymatic reaction called methylation. At a most basic functional level, methylation results in the silencing of the gene, and the bond formed between the DNA cytosine and the methyl group is strong, causing a stable but potentially reversible change in gene expression. However, DNA methylation patterns can remain throughout the life of the cell and may be passed along for multiple generations potentially causing the organism's genes to behave differently, and providing an explanation for how early life experiences can have a long lasting effect on the brainand influence behavior and health in later life."
Lei Cao-Lei4 reported" The NR3C1gene, coding for the glucocorticoid receptor (GR), is the prime candidate gene for epigenetic influence on outcomes as it plays a key regulator role in HPA axis functioning. Results showed that increased maternal depressed mood in the third trimester was associated with increased methylation of the NGFI-Abinding site in NR3C1 in the infants, which then predicted increases in their HPA stress reactivity."
Millennium Development Goal 5 of WHO focus on improve maternal mental health.16 The World Health Organization (WHO) and United Nations Population Fund (UNFPA)had jointly initiated a program to integrate mental health needs into existing maternal and child health policies, plans and activities.
Balaji Bharadwaj reported that The NIMHANS, Bangalore, has started a mother‑baby Unit and a postdoctoral training course in perinatal psychiatry and women’s mental health.17
Rahul Shidhaye et al18 operationalized World Health Organization (WHO) Mental Health Gap Action Plan (mhGAP) guidelines19 by integrating Mental Health Care Plan with primary health care for Sehore district during the period August 2011 to March 2014. Suggested mental healthcare plan (MHCP) a robust policy context for designing and implementing a district-level MHCP that will help rejuvenated DMHP. They also include interventions for maternal depression as it is the second leading cause of disease burden in women worldwide.
Conclusion
The integration of mental health care to maternal health care is indispensible need of today. The importance of antenatal depression has been largely underestimated with the focus of research maintained on postnatal depression. Health care providers working in reproductive and child health should be trained to recognize signs and symptoms suggestive of a psychological problem and to provide counseling to the women about physical changes and stress and as well as provide effective psychological support and interventions if required. High risk suspected cases should be immediately referred to the psychiatrist and proper follow-ups should be done. Special free OPD’s comprising female doctors can be run to address women’s psychological issues. Partner & Family members should be educated of risk factors and long term consequences on child's health. They should be encouraged to provide support, care and healthy environment to the antenatal women. In our institute we have a special OPD at psychiatry department for mental health of women by the name “VYAMM” which is a small positive step towards a big goal.
