ABSTRACT

OBJECTIVES: The present study aimed to improve breast cancer (BC) awareness and practices using Information, Education and Communication (IEC) modules and health educational sessions for women and primary healthcare providers in low socioeconomic community of Mumbai. DESIGN: Pre-post quasi-experimental design. SETTING: The study was conducted in a lower socioeconomic area of G-South ward of Mumbai, Maharashtra. The baseline and endline survey was conducted using structured interview schedules. PARTICIPANTS: 410 women were selected, aged between 18 and 55 years who were not pregnant, lactating or diagnosed with BC. INTERVENTION: A health education-based intervention module was developed to educate women through group and individual sessions. OUTCOMES: Summative indices were constructed to understand the net mean difference in knowledge of signs, symptoms and risk factors. Analysis of variance (ANOVA) and paired t-test were used to check the significant improvement of intervention. RESULTS: Our results showed statistical significance in difference in mean knowledge scores for both signs and symptoms (mean difference (MD) 4.09, SD 4.05, p<0.00)) and risk factors of BC knowledge (MD 5.64, SD 4.00, p<0.00) among women after intervention. There was a marked improvement in the knowledge of BC among women with low education category. A significant improvement in knowledge of symptoms and risk factors among health workers was also observed. Our interventions resulted in positive change in breast examination practices. The breast self-examination (BSE) practices improved from around 3% to 65% and around 41% additional women went for clinical breast examination after intervention. CONCLUSIONS: This study found a significant improvement in knowledge of BC signs and symptoms, risk factors and BSE practices among study participants following our health education interventions among these subpopulations. This evidence calls for inclusion of similar interventions through health education and capacity building of primary healthcare providers in national programmes.

ABSTRACT

BACKGROUND: Breast cancer (BC) is leading cancer among women in India accounting for 27% of all cancers among women. Factors that make the policymakers and public health system worried are rising incidence of breast cancer in India and more importantly high death rates among breast cancer patients. One of the leading causes of high breast cancer deaths is lack of awareness and screening leading to the late presentation at an advanced stage. Therefore, the current research aimed to understand the knowledge of breast cancer symptoms and risk factors among women in a low socio-economic area of Mumbai. METHODS: A cross-sectional study was conducted at Prabhadevi, Mumbai and primary data was collected from 480 women aged 18-55 years. Structured questionnaire was used to collect quantitative data pertaining to awareness, signs and symptoms of breast cancer. Bivariate and multivariate regression techniques were used for understanding of the socio-demographic differentials in breast cancer awareness among women. RESULTS: The study found that around half (49%) of the women were aware of breast cancer. The women who were aware of breast cancer considered lump in breast (75%), change in shape and size of breast (57%), lump under armpit (56%), pain in one breast (56%) as the important and common symptoms. Less than one-fifth of the women who were aware of breast cancer reported early menstruation (5.6%), late menopause (10%), hormone therapy (13%), late pregnancy (15%) and obesity (19%) as the risk factors for breast cancer. The multivariate regression analysis showed women who had more than 10 years of schooling (Adjusted Odds Ratio: 3.93, CI: 2.57-6.02, P < 0.01) were about 4 times more likely to be aware of breast cancer than women who had less than 10 years of schooling. CONCLUSION: In conclusion, knowledge of danger signs and risk factors of breast cancer were low among women in the community. This may lead to late detection of breast cancer among women in the community. Therefore, the study calls for advocacy and larger intervention to enhance knowledge of breast cancer among women in the particular region with a special reference to women with low education.

ABSTRACT

Husbands' alcohol use has been associated with family-level stress and intimate partner violence (IPV) against women in India. Joint family systems are common in India and IPV often co-occurs with non-violent family maltreatment of wives (e.g., nutritional deprivation, deprivation of sleep, blocking access to health care). Alcohol use increases for some parents following the birth of a child. This study examined 1,038 postpartum women's reports of their husbands' alcohol use and their own experiences of IPV (by husband) and non-violent maltreatment from husbands and/or in-laws. We analyzed cross-sectional, quantitative data collected in 2008, from women (ages 15-35) seeking immunizations for their infants <6 months at three large urban health centers in Mumbai, India. Crude and adjusted logistic regression models estimated associations between the independent variable (husbands' past month use of alcohol) and two dependent variables (postpartum IPV and maltreatment). Overall, 15% of husbands used alcohol, ranging from daily drinkers (10%) to those who drank one to two times per week (54%). Prevalence of postpartum IPV and family maltreatment was 18% and 42%, respectively. Prevalence of IPV among women married to alcohol users was 27%. Most abused women's husbands always (27%) or sometimes (37%) drank during violent episodes. Risk for IPV increased with a man's increasing frequency of consumption. Women who lived with a husband who drank alcohol, relative to non-drinkers, were more likely to report postpartum IPV, aOR = 2.0, 95% confidence interval (CI) = [1.3, 3.1]. Husbands' drinking was marginally associated with increased risk for family maltreatment, aOR = 1.4, 95% CI = [1.0, 2.1]. Our findings suggest that men's alcohol use is an important risk factor for postpartum IPV and maltreatment. Targeted services for Indian women contending with these issues are implicated. Postpartum care offers an ideal opportunity to screen for IPV, household maltreatment, and other health risks, such as husband's use of alcohol. There is need to scale up proven successful interventions for reducing men's alcohol use and design strategies that provide at-risk women protection from alcohol-related IPV.

ABSTRACT

BACKGROUND: Intimate partner violence (IPV) victimization is linked to a broad range of negative maternal health outcomes. However, it is unclear whether IPV is directly related to poor maternal outcomes or whether IPV is a marker for other forms of chronic, mundane maltreatment of women that stem from the culture of gender inequity that also gives rise to IPV. To determine the prevalence of non-violent forms of gender-based household maltreatment by husbands and in-laws (GBHM), and violence from in-laws (ILV) and husbands (IPV) against women during the peripregnancy period (during and in the year prior to pregnancy); to assess relative associations of GBHM, ILV and IPV with maternal health. METHODS: Cross-sectional data were collected from women <6 months postpartum (n = 1,039, ages 15-35 years) seeking child immunization in Mumbai, India. Associations of IPV, ILV and GBHM during the peripregnancy period with maternal health (prenatal care in first trimester, no weight gain, pain during intercourse, high blood pressure, vaginal bleeding, premature rupture of membranes, premature birth) were evaluated. RESULTS: One in three women (34.0 %) reported IPV, 4.8 % reported ILV, and 48.5 % reported GBHM during the peripregnancy period. After adjusting for other forms of abuse, IPV related to pain during intercourse (AOR = 1.79); ILV related to not receiving first trimester antenatal care (AOR = 0.49), and GBHM remained associated with premature rupture of membranes (AOR = 2.28), pain during intercourse (AOR = 1.60), and vaginal bleeding (AOR = 1.80). CONCLUSION: After adjusting for ILV and IPV, peripregnancy GBHM remained significantly associated with multiple forms of maternal morbidity, suggesting that GBHM is a prevalent and reliable indicator of maternal health risk.

ABSTRACT

OBJECTIVES: To determine the prevalence of non-violent, gender-based forms of maltreatment of women by husbands and in-laws [i.e., gender-based household maltreatment (GBHM)] during pregnancy and postpartum; to clarify the role of GBHM in compromising infant health, and whether this role extends beyond that previously observed for intimate partner violence (IPV). METHODS: Cross-sectional, quantitative data were collected from women (ages 15-35) seeking immunizations for their infants <6 months of age (N = 1061) in urban health centers in Mumbai, India. Logistic regression models were constructed to assess associations between maternal abuse (perinatal IPV, in-law violence and GBHM) and recent infant morbidity (diarrhea, respiratory distress, fever, colic and vomiting). RESULTS: More than one in four women (28.4%) reported IPV during their recent pregnancy and/or during the postpartum period, 2.6% reported perinatal violence from in-laws, and 49.0% reported one or more forms of perinatal GBHM. In adjusted regression models that included all forms of family violence and maltreatment, perinatal GBHM remained significantly associated with infant morbidity (AORs 1.4-1.9); perinatal IPV and in-law violence ceased to predict infant morbidity in models including GBHM. CONCLUSIONS: Findings indicate that non-violent expressions of gender inequity (e.g., nutritional deprivation, deprivation of sleep, blocking access to health care during pregnancy) are more strongly associated with poor infant health than physical or sexual violence from husbands or in-laws in urban India. These results strongly suggest the need to expand the conception of gender inequities beyond IPV to include non-violent forms of gendered mistreatment in considering their impact on infant health.

ABSTRACT

OBJECTIVE: The objective was to examine postpartum contraception utilization among Indian women seeking immunization for their infants in three low-income communities in Mumbai, India. STUDY DESIGN: We conducted a cross-sectional questionnaire of low-income postpartum women seeking immunization for their infants at three large urban health centers in Mumbai. Contraceptive utilization data were collected as part of a larger study focused on the impact of postpartum domestic violence on maternal and infant health. Descriptive, bivariate and multivariate analyses were conducted to describe and identify predictors of postpartum contraceptive utilization. RESULTS: Postpartum women aged 17-45 years (N=1049) completed the survey; 44.5% (n=467) reported resuming sexual relations with their husbands. Among these women, the majority (65.3%; n=305) reported not currently using contraception. In multivariate analyses, women who did not discuss postpartum family planning with their husbands, had not used contraception previous to the recent birth, and had experienced physical violence or forced sex were more likely to not use postpartum contraception (adjusted odds ratios=1.47-1.77). Among the 162 women using contraception, the most common time to initiation of contraception was 5 weeks postpartum, and the most common method used was condoms 77.8% (n=126). CONCLUSION: Contraception nonuse was common among urban, low-income postpartum women in India. This study highlights the importance of developing interventions to increase use of highly effective contraceptive methods postpartum, and that spousal violence and lack of marital communication may present barriers to postpartum contraception utilization. Infant immunization may represent an opportunity for provision of contraceptives and contraceptive counseling. IMPLICATIONS: This original research study is a unique contribution to the literature because it presents data regarding the nonuse of postpartum contraception among women seeking immunizations for their infants in urban centers in a developing country. It also reveals barriers to not using postpartum contraception and provides data for future interventions.

ABSTRACT

The National Family Planning Programme of India had introduced condom as one of the family planning methods in the late 1960s. Condom was promoted as a family planning method through social marketing since its inception. With the increasing prevalence and incidence of sexually transmitted infections (STIs) including HIV/AIDS, condom was also promoted as a dual method for protection against both unintended pregnancies as well as sexually transmitted infections. Despite efforts at various levels, the overall use of condom among couples in India is low. Here we present literature review of studies to understand the condom acceptability among couples in India. Specifically, the paper assesses research and programmes that have been carried out to increase the use of condom among couples; determinants of condom use; reason for not using condom; and perception versus experience of condom failure. The reported problems related to condom use included non acceptance by partner, perceived ineffectiveness, less comfort, lack of sexual satisfaction, husband's alcohol use, depression, and anxiety, and not available at that instant. The role of media in the promotion of condom use was indicated as an important way to increase awareness and use. Multiple strategies would help in acceptance of male condom.

ABSTRACT

This study involved evaluation of the short-term impact of the RHANI Wives HIV intervention among wives at risk for HIV from husbands in Mumbai, India. A two-armed cluster RCT was conducted with 220 women surveyed on marital sex at baseline and 4-5 month follow-up. RHANI Wives was a multisession intervention focused on safer sex, marital communication, gender inequities and violence; control participants received basic HIV prevention education. Generalized linear mixed models were conducted to assess program impact, with cluster as a random effect and with time, treatment group, and the time by treatment interaction as fixed effects. A significant time by treatment effect on proportion of unprotected sex with husband (p = 0.01) was observed, and the rate of unprotected sex for intervention participants was lower than that of control participants at follow-up (RR = 0.83, 95 % CI = 0.75, 0.93). RHANI Wives is a promising model for women at risk for HIV from husbands.

ABSTRACT

BACKGROUND: Women living in slum communities in India too often contend with depression. Local social support in other national contexts has been shown to reduce such risks. Less research in this area has been done in India and specifically with monogamous wives. METHODS: This study involved a household sample of women reporting husband's partner violence or heavy alcohol use (N=220). Participants were assessed on high social support in the community, and number of depressed days in the past 30 day (dichotomized as 10+ vs.<10 day). Logistic regression analyses assessed associations between local social support and depression, adjusting for demographics, spousal violence, and husband risky alcohol use. RESULTS: High local social support was reported by 40% of women; 33% reported never having local social support. Women with high local social support were significantly less likely to report depression (AOR: 0.53, 95% CI: 0.30-0.94), even after adjusting for husbands' recent spousal violence perpetration and his risky alcohol use, both of which were also significantly associated with depression. LIMITATIONS: The data analyzed for this study are vulnerable to self-report and recall biases, as well as issues around social desirability. These analyses are further limited due to the use of single item measures to assess depression and local social support. CONCLUSIONS: Local social support reduces risk for depression among women in Mumbai contending with husbands' spousal violence and risky alcohol use. These findings support the likely utility of community-based social support building to reduce risk for depression among this vulnerable population of women.

ABSTRACT

To assess the awareness of cervical cancer among couples, data were collected from two urban slums community in Mumbai. A total of 1958 married women aged from 18 to 49 and their husbands were selected using simple random sampling. Women (37.7%) were significantly more aware of cervical cancer than husbands (8.7%). A slight agreement (kappa statistics=0.16) was observed between husbands and wives on awareness of cervical cancer. Significantly higher percentages of wives were aware of pap smear test than husbands. Overall, awareness of cervical cancer and pap smear test among couples is low. There is need to educate and motivate both of them to participate in cervical cancer screening program.

ABSTRACT

This study aimed to determine the factors influencing the use of spacing contraceptive methods in India, particularly from men's perspective. Data were obtained through a semi-structured interview schedule from 2,687 married men aged between 18 and 40 years from central Mumbai City, India, during 1999. Chi-squared tests and binary logistic regression analysis was carried out to determine the relationship between various variables and the likelihood of a couple using spacing contraceptive methods. Of the 2,687 couples, 1,395 (51.9%) were using one or other method of spacing contraceptives and 1,292 (48.1%) were not using any method at the time of survey. Male participation in contraceptive use was 23% (condom and withdrawal). The results indicate that the use of spacing contraceptive methods was significantly higher among those couples where the men desired one or two children (OR=4.3), had knowledge of five or more contraceptive methods (OR=1.9) and discussed with their wives obtaining family planning information (OR=3.2), spacing (OR=2.7) and permanent (OR=2) contraceptive methods. Age, income, desired number of children, knowledge of a greater number of contraceptive methods, inter-spouse communication regarding obtaining family planning information, spacing and permanent methods were found to be strong predictors of the use of spacing contraceptive methods. The study underlines the importance of intervention programmes aimed at promoting a small family norm, increasing the number of contraceptive choices available and encouraging inter-spouse communication. Hence, policymakers and programme managers should encourage interventions in this direction, targeting couples to enhance the use of spacing contraceptive methods.

ABSTRACT

Since men are the dominant decision makers in India, it is prudent to discover the knowledge, perception, attitudes and contraceptive practices of men to improve their involvement in the reproductive health needs of families. Three thousand and seventy-two married men from a tribal Primary Health Centre (PHC) area in Thane district of Maharashtra State, India were surveyed with special emphasis on investigating the reasons for not accepting male methods. The majority of them not only had no concept of family spacing, but had not even taken any initiative to improve their knowledge or acceptance of condom/ vasectomy. Men who were aware of contraceptive methods had little knowledge of their correct use. Of the men, 53.7% had positive views about their role in family planning while 66.2% of men stressed the need to improve the acceptance of male methods by providing knowledge and information through sources such as radio, television, door-to-door campaigning and interpersonal communications. Thirty per cent emphasized the need to improve the availability and quality of services. This study indicates a pressing need for effective intervention strategies, both at the community and the clinic level, backed with efficient counselling, motivation and provision of services in rural and remote areas.

ABSTRACT

A disease prevalence and immunization coverage survey in a typical slum in Bombay in the year 1988 revealed 93 children with residual poliomyelitis amongst 14,439 children below 9 years of age, indicating high (33.0/100,000 population) annual incidence of poliomyelitis. Only 62 (66.6%) of these 93 lame children sought admission in hospital during the acute phase of illness. The high incidence was attributed to a low immunization (OPV) coverage level in the most vulnerable age group. The immunization coverage for 3 doses of oral polio vaccine below 2 years of age was 43.5%. A large number of children were not commencing their immunization schedule at the right age. The survey indicated a poor "community participation" in the immunization programmes due to a poor "health awareness".

ABSTRACT

In Bombay, the immunization coverage with 3 doses of oral polio vaccine in children below 2 years of age has reached 80%. As a result, the high incidence of over 11/100,000 population prevailing in the 6 year period (1982-1987) has declined to around 6 in 1988 and 1989. The decline was observed both in the slum and in the "non-slum" population. The incidence in the slum population has reduced from over 22/100,000 population to around 11. In the morbidity, a subtle "age shift" to older children was noticed in 1988-1989. Average age-specific incidence (for age group below 1 year) was found to be 1.04/1000 children in 1988-89 as against 2.47 in the preceding 6 years. The proportion of "Non-Immunized" cases gradually declined from 65.8% in 1982 to 49.7% in 1989 and conversely, the proportion of fully immunized cases increased from 14.5% in 1982 to 22.7% in 1989. The attack rates per 1000 children below 1 year of age in the inadequately/"Non-Immunized" and the fully immunized children were found to be 2.822 and 0.224 respectively. The sharp peak in the morbidity observed in the 3rd quarter of an year (July to September) has been replaced by almost even distribution of cases in all the quarters of an year. All the three polioviruses were encountered through out the year. Although, poliovirus type 1 was the most predominant of viruses, its proportion was on decline. The portion of isolation of "Non-Polio" viruses has increased from 6.8% in 1982 to 16.2% in 1989.(ABSTRACT TRUNCATED AT 250 WORDS)
