Antenatal depression is a depression occurred during the period of pregnancy of mothers. Depression is the 4th leading causes of disease burden and the largest causes of non- fatal burden accounting for almost 12% of all total years lived with disability worldwide(1).it is one of the most ancient and common diseases of the human race. Depressed patients are at least as heavily disabled as patients affected by other chronic diseases such as hypertension, rheumatoid arthritis and diabetes (2).
Depression is the most prevalence psychiatric disorder during pregnancy. Almost one woman out of four was experience depression at some point in her life, most commonly during the childbearing years(3) . Depressive disorders are not only common and chronic among women throughout the world but also the principal source of disability (1-3).
Antenatal depression often precedes postnatal depression (4) and causes great suffering to the women and her family(3) . On top of that, untreated depression is associated with higher rates of morbidity and mortality. Similarly, discontinuation of antidepressant drug therapy in women with medication responsive illness carries a high risk for relapse and suicide attempts (5). More worryingly, per-natal depression has been found to be linked with infant under nutrition in many low income countries(6).
Negatively and low caregiver responsiveness may contribute to high rates of insecure attachment found among infants of depressed mothers (7). Children of depressed mothers are also at risk for slower cognitive development (8), low activity, difficulty interacting with unfamiliar and adults and unresponsiveness (9). Biomedical consequences including an increased risk for breastfeeding problems (10) , eating and sleep disturbance (11) , and a reduced likelihood of receiving preventative health care (12) or daily vitamin supplementation (13). Depressed mood during pregnancy has also been associated with poor attendance at antenatal clinics, substance misuse, low birth weight, and preterm delivery (7, 8).
Antenatal depression is defined as the occurrence of a depressive episode in women during pregnancy. Prenatal depression is a non- psychotic depressive episode ranging from mild to severe symptoms that occur while a woman is pregnant period(14, 15). The WHO ranked depression as a single largest contributor to global disability in 2015.Depression has been reported more common among female population group as compared to male population group (16).
Depression affects an estimated 10 % to 20% of pregnant women worldwide. Traditionally, pregnancy was viewed as a time protective against developing depression; consequently, the existence and consequences of have received little attention in either obstetrical, psychiatric, family medical practice, or mental health services. Depression is characterized by feeling of low self-worth, loss of interest, feelings of regret, restlessness, loss of appetite, feelings of fatigue, and poor concentration. Prenatal depression is a non-psychotic depressive episode ranging from mild to severe symptoms that occur while a woman is pregnant or during postnatal period.
Depression is one of the top contributors of global burden of diseases, which affects around 322 million people worldwide and is the leading reason for suicide. WHO, Global Health Estimates of 2015 reported that 788,000 people died due to suicide for every person who dies of suicide, 20 additional people attempted suicide. Depressive disorders led to a global total of over 50 million Years Lived with Disability in 2015 throughout the world(1, 2).
The estimated prevalence of depression worldwide is increased by 18.4% from 2005 to 2015 in the world(3).Depression in pregnancy may diminish one’s capacity for self- care including inadequate nutrition, drug or alcohol abuse, and poor antenatal clinic attendance all of which may compromise a women’s physical and mental health and may reduce optimal fetal monitoring or restrict the growth and development of the fetus although nearly 90% of the world’s children live in low and middle income countries (3).
In Ethiopia, depression is the third leading cause of burden of diseases and is also predicted to become the second leading cause of the global disease burden by the year 2020 (4). Depression is an emotional or affective state where a person may feel sad, lonely, or miserable with a “lack of interest” in their usual pleasurable activities (17).
In conclusion enormous numbers of individuals are being affected with general depression and it is responsible for 850,000 deaths per year. Results showed that 15% of the population from high income countries to 11% for low income countries is suffering with this problem. Antenatal depression is one of the ever maternal mental health problems that can be categorized under general depression which affects 10-15% of women before delivery.
The major aim of this study was to determine the prevalence and associated factors of antenatal depression among women attending antenatal care follow up at Michu clinic in ACSH.
Therefore, early identification of maternal depression and the associated factors are potentially an effective strategy for decreasing maternal mortality and morbidity related to antenatal depression so that early screening of antenatal depression would improve the ability to recognize this disorder and enhances care that ensures appropriate health outcomes.
The evidence from this study would assist policy makers and program planners to take action to reduce the mortality and morbidity of mothers would able to take appropriate measurement.
Additionally, this study would provide relevant information for health workers to assess the magnitude and associated factors of antenatal depression which leads them to provide intensive professionally based antenatal support, to remain alert for associated factors of antenatal depression and would implement psychosocial support during the antenatal period and at the last it would be as an initial for other researchers for additional investigation.
Worldwide depression is the 4th leading of diseases burden and the largest causes of non-fatal burden accounting almost 12% of all years lived with disability worldwide(1). AD precedes post-natal depression(4). Most of the core maternal symptoms of prenatal depression such as sleep disturbance and fatigue are frequently attributed to normal response of motherhood, which lowers the detection of prenatal depression (18).
One of the main components of sustainable development goal is improving maternal health and the vitality of mental health is stated through the theme “no health without mental health.” In developing countries, one in three to one in five pregnant and postpartum mothers have mental illness(14) . To realize sustainable development goals, efforts must include procedures to avert and manage the issue of maternal mental health during pregnancy and following birth of a baby(15) . Prenatal depression’s even milder symptoms impose a considerable health, social, and economic impact on the woman, her family, and her country at large (19, 20) .
Prevalence of antenatal depression
Epidemiological data suggests that 15% of women are depressed at any one time throughout the world(21). The prevalence of AD varies across different countries. For instance, the prevalence of AD ranges from 7 to 15% in high-income countries throughout the world (22). The prevalence of AD is also twofold higher among women from low- and middle-income countries (20%) as compared to women from high-income countries in the world (10%),(15, 18).
Some researchers suggest that mothers of young children may have high rate of depression than general population of women in the world (23). The prevalence of AD ranges from 19 to 25% in low-and middle-income countries worldwide(24).
The prevalence of AD in Asia among 543 pregnant women attending antenatal care with beck depression inventory was used to assess the individual’s depression condition and the prevalence was 15%-28% (8-11). In Pakistan 28%-57% among 312 pregnant women attending ANC follow up at public health center with BDI (I) (12) and 35%-50% in Latin America among 234 pregnant mothers attending ANC follow up by BDI (I), (13).
A cohort study of women attending a district hospital antenatal clinic in Goa a specific place in china with study participants of 453, and community based study from Tamil Nadu, India with a total pregnant women of 387reported a prevalence of 23% and 19% respectively where BDI (I) was used to assess the individuals depression condition (25, 26).
Another community cohort study from Pakistan reported a prevalence of 28% (27). A meta-analysis shows a prevalence of AD is also high ranging from 0.5% to 51% in Pakistan (10) . The prevalence of maternal depression is estimated to 15%-28% in Africa among 256 pregnant mothers attending ANC by BDI (II), (13) .
The prevalence of AD in South Africa is as high as 30-50% in one cross sectional study conducted in rural area of South Africa among 500 pregnant women attending ANC follows up in public health center(13) .
In Ethiopia very few published studies are their concerning AD. These published researches show the prevalence of depression among pregnant women generally ranging from 4.4 % to 12% (28-30). The prevalence of antenatal depression is reported to be 31.2% in Adama Hospital among 345 pregnant mothers attending ANC at public health center by using BDI II (31), 31.1 % in Maichew among 209 women attending antenatal care of the total women attending ANC follow up out of the source population of 600 pregnant mothers in public health centers using beck depression inventory to assess individual’s depression condition with a cutoff point greater or equals to 14 (32), 29.5% in Sodo district of Gurage Zone among 254 pregnant mothers with BDI I with a cutoff point greater or equals to 14 (33) .
24.9%inAddis Ababa Public Health Centers among 542 pregnant mothers attending ANC follow up at public health center by using BDI I with a cutoff point greater or equals to 14 (34).23% in Gondar University Hospital among 388 pregnant mothers attending ANC follow up at Gonder University Hospital with BDI (35, 36) and a recent study in Dubti hospital located 10 Km from Samara which is the capital city of Afar Regional state with prevalence of 17.9% and the sample size was 363 among a total of 4560 women following antenatal care per one year and the research was conducted with Beck depression inventory II with a cutoff point > or equals to 17 to assess the individual’s depression condition(37).
The objective of the current review was to present an over view on the magnitude and associated factors of perinatal depression in Ethiopia.
Determinants of antenatal depression
Different studies conducted so far in different area reported Risk factors can be mentioned like socio-demographic characteristics, social support, obstetrics factors, previous psychiatric history and substances use for depression among pregnant mothers such as being young age was associated with AD in Rawalpindi, Pakistan (11), low income associated with AD in Jamaica (12), lower educational attainment and obstetric factors in Rawalpindi, Pakistan (11) history of depression (11-13), history of miscarriage and pregnancy termination (7), concomitant high anxiety in pregnancy (38), low self-esteem (27) and low social support (37, 39, 40).
Women from a developing country like Ethiopia are usually exposed to risk factors for the development of AD like poor socioeconomic status, unintended pregnancy, and gender-based violence and history of childhood sexual abuse in Ethiopia (28, 41).
Socio-demographic characteristics, Pregnancy planning, social support, previous psychiatric history, obstetric factors and marital conflict were significantly associated with AD, a cross sectional study conducted in Northern Ethiopia at Dubti Hospital (37).
Bivariable logistic regression analysis showed that maternal education, average family monthly income, history of complication in previous pregnancy, and previous history of depression were statistically associated with antenatal depression in Northern Ethiopia Dubti Hospital (37).
In multivariable logistic regression analysis marital conflict, pregnancy planning, and social support were found to be significantly associated with AD. Those women who had marital conflict were about six times more likely to have AD as compared to those who had no marital conflict (37). Women who had planned their current pregnancy were 96% less likely to have antenatal depression as compared to women who had no planned pregnancy compared to women who had low social support, women who had medium social support less likely to have antenatal depression (37).
Sociodemographic characters tics of antenatal depression
The incidence of AD is affected by different contributing factors among these socio demographic characteristics is one of the leading factors for AD. This has been revealed by different studies.
Firstly, when we see age, Young mothers were found to be at increased risk of AD than mothers of older age in British(14) (35).In contrast, a cross sectional study which was conducted in Turkish women revealed that the prevalence of AD was higher in older women than younger (14). Beside a study in China tells the absence of association between AD and maternal age (5). But in Ethiopia it has been revealed by different studies that Young mothers were found to be at increased risk of AD than mothers of older age(27) .
Secondly, there is also evidence on the difference in the incidence of AD between educated and non-educated mothers with the higher prevalence of AD in uneducated in developed country like Harvard University(27). But this result is in opposite with other findings where educational status of the mother did not associate with AD in the Rural developing world (5). Another cross sectional study in Qatar tells women who are educated are more vulnerable for the problem (22).In Ethiopia specifically Northern part in Dubti hospital reveled that Non-educated women have higher prevalence than educated women in a cross sectional study(37).
Thirdly, single mothers appear to have greater risk of AD in one study in rural South Africa (21).But in Ethiopia majority of participants were married and the prevalence is higher in married than women who does not married in a cross sectional study in Northern Ethiopia particularly Dubti Hospital (37).
Fourthly women who are in low economic status are also at high risk for AD in one cross sectional study in Harvard University (27) and in South Africa(25). Another study conducted in middle and low income countries in North East Africa with a systemic review study showed similar finding that women who are in low economic status have higher prevalence (15, 22, 37, 39) and a study conducted in Ethiopia revealed similar finding that women with low income status were found to have higher prevalence of AD. Almost 90 percent of study participants had reported that they earn an average family monthly income of more than500 Ethiopian Birr (the minimum Ethiopian wage during that time and Young mothers were found to be at increased risk of AD than mothers of older age(37).
Fifthly, a Socio cultural factor ritual is among the list of factor which contributed for the incidence of AD in one cross sectional study in British (14) but there is no conducted result about socio cultural factor in Ethiopia.
Sixthly, In different researches it has been mentioned that mothers who are working are also affected with the problem a cohort study in South Africa (25, 39), comparatively mothers who are unemployed are more at risk to develop AD than employed in a cross sectional study in Ethiopia (15, 29).
Seventhly, in Ethiopia Three hundred forty-five (96.6%) and 205 (57.4%) women were married and had attended formal education, respectively.
Social support
This was evident in different studies. On the study in developed countries which was conducted in 2010-2011 on 285 women by BDI I who gave birth in the Department of Obstetrics, Gynecology and Gynecologic Oncology at the University Hospital in Bydgoszcz has been mentioned that the child birth without the presence of any relatives was mentioned as a factor for AD but another study concluded that there was no association between AD and lack of social support in Jamaica (12, 38, 39).
The incidence of AD Women who have poor husband support were found to be at increased risk of AD in a cohort study in rural population in a developing country worldwide (5), But in one cross sectional study conducted in Northern Ethiopia reveled that marital problem was a contributing factor for maternal depression in which (27.2%) had encountered a conflict with their husbands in the last 12 months preceding the study.
For instance, in Ethiopia at least one in five women reported intimate partner violence(42) and women having history of intimate partner violence are 3 to 5 times likely to develop AD (19, 20, 43, 44). Despite extensive variations in the prevalence and associated factors of AD across different communities of Ethiopia, there is no pooled evidence regarding the overall prevalence and potential associated factors of perinatal depression.
Social support loss and marital conflict had higher prevalence of AD than women who had no conflict with their husband and women who had no social support in a study conducted in Ethiopia(37) .
History of substance use
Substance use particularly alcohol or khat, are not uncommon before or during pregnancy. Multiple addictions are also common, in particular alcohol with tobacco and alcohol with cannabis. A research conducted in University Hospital in Bydgoszcz has been mentioned that women using substance like khat and alcohol are associated with AD(27). On a systematic review of the prevalence of antenatal depression among Women with Substance use, an abuse history, or Chronic illness by including seventeen papers on patient health questionnaire 9 assessing depression between 3 and 36 weeks of antenatal period there were high rates of AD among substance-using women of khat and alcohol and those with current or past experiences of abuse in Southwest Ethiopia (39, 45).
Again another study in Ethiopia revealed that Prevalence of major depression was 12.4% for past-year pregnant women, of these women’s 35.4% had nicotine dependence. Twenty-one (5.9%) of the study participants had used alcohol at least once in the last 30 days but none of the participants had reported current khat chewing(37).
Obstetric factors of antenatal depression
A study conducted in Iran indicated that unwanted pregnancy is not a risk factor for AD(40). A research done on risk factor of depression in rural area of Isfahan province, Iran prime-paresis women were at higher risk for antenatal depression compared with multipara, prime-gravidia, multigravida (29). In one cohort study conducted in Southwest Ethiopia (26, 29, 39, 46) More than three-fourth (76.2%) of pregnant women were in either the second or third trimester during the time of the study. A national survey in Ethiopia conducted in 2013 showed an overall unplanned pregnancy rate of 24%.
Due to the associated higher risk women are at increased risk of having obstetric complications such as preterm labor, preeclampsia, fetal growth restriction, abruption placenta, and associated fetal and maternal complications(18). Women having such problems are usually less likely to seek and get care for themselves as well as their child, which intern leads to pre-term birth, low birth weight, and growth restriction (24, 47-49).
Another research conducted in Northern Ethiopia specific place of Maichew, two hundred eighty-four (79.6%)of the women had planned their current pregnancy, of 221 women who had a history of pregnancy, 55(24.9%) had a history of complication during previous pregnancy among 388 the participants in the study.
Previous psychiatric history
PPD has been found to elevate the risk of AD. A research conducted in developed countries, for example in Brazil there was a cross sectional study on the assessment of prevalence and associated of previous psychiatric disorder with bio-social-demographic factors, family history of psychological disorders was mentioned as a contributing factor for AD(17).
There are also other studies which tell that women with PPD found to be at increased risk of AD, a cohort study conducted in developing countries throughout the world (5).
There are plenty of studies which tell that women with previous history of depression found to be at increased risk of AD, a cohort study conducted on different part of Ethiopia(32, 37). In general the study revealed that women who had PPD especially depression had higher prevalence than women who had no previous psychiatry history and About 97 (27.2%) of the study participants reported a previous history of depression (37).
