Achieving global targets on breastfeeding in Thailand: gap analysis and solutions

Mothers' needs and wishes for breastfeeding support in workplaces in Thailand: a qualitative study

BACKGROUND

Returning to work is a barrier to breastfeeding. Although the Department of Labour Protection and Welfare (DLPW) in Thailand encourages employers to initiate a breastfeeding corner - a designated area where mothers can express their breastmilk privately and comfortably - in their workplace to support lactating employees, little is known about what kind of support mothers would like to continue breastfeeding after returning to work. This research aimed to explore mothers' needs and wishes for breastfeeding support in the workplace.

METHODS

This qualitative study used focus group discussions to collect data from female employees who had a child aged 6 - 24 months in factories that had initiated a breastfeeding corner between 1 October 2021 and 30 September 2022. The focus group discussions were held between June and July 2023. We employed semi-structured questions relating to breastfeeding support in their workplaces (e.g., a breastfeeding corner, lactation break, providing information or knowledge), baby food marketing in workplaces, and recommendations to improve breastfeeding support for working mothers. We applied thematic analysis to analyse the data.

RESULTS

Nineteen mothers from five factories located in Bangkok and surrounding provinces participated in the study. All participating factories had a breastfeeding corner in a first aid room, and no lactation breaks were given. Therefore, lactating employees spent time during their breaks pumping breastmilk. Furthermore, the lactating employees did not acquire any information or education about breastfeeding from the workplace during pregnancy or after delivery but rather obtained this from health system services and digital platforms. They also received support from family, health professionals, and colleagues when they returned to work after giving birth. Lactating employees would like employers to provide specific lactation breaks. They also wanted credible information or knowledge about breastfeeding to be provided during pregnancy and after giving birth, together with other social support.

CONCLUSIONS

The Department of Labour Protection and Welfare, the Department of Health, and the Thai Breastfeeding Centre Foundation could collaborate with other relevant organisations to support employers in establishing breastfeeding support in their workplace.

A qualitative descriptive study of Thai fathers' experiences in supporting their partners' breastfeeding

Background

The crucial role of fathers in the well-being of mothers and infants is widely acknowledged. This study focuses on the specific context of how Thai fathers support their partners in breastfeeding, with the goal of gaining a deeper understanding of the strategies they employ in providing this support.

Objective

This study aimed to explore the experiences of fathers in supporting their partners in breastfeeding.

Methods

The study used a qualitative descriptive design from December 2018 to February 2020. Nineteen Thai fathers were purposefully selected, each with partners and infants who did not face any complications that would serve as barriers to breastfeeding. Data collection occurred at vaccination clinics and family planning wards in two major hospitals in Chiang Mai province, Thailand. The data were collected through in-depth interviews, and a thematic analysis approach was employed for data analysis.

Results

Four themes emerged: a) Facing barriers to breastfeeding support, b) Believing in the value of breast milk, c) Seeking ways to increase milk supply, and d) Making an effort to support continued breastfeeding.

Conclusion

Thai fathers demonstrated a strong eagerness to support their partners in sustaining breastfeeding. Their willingness highlights the importance of nurses, midwives, and other healthcare providers providing additional education and support to empower them as supportive partners to mothers.

Self-management of type 2 diabetes mellitus in pregnancy and breastfeeding experiences among women in Thailand: Study protocol

Women with type 2 diabetes mellitus are at a higher risk of pregnancy complications. Although traditional beliefs and practices influence diabetes management and breastfeeding, recommendations integrating Thai cultural beliefs in maternal care are lacking. The purpose of this study is to describe diabetes self-management in pregnancy and breastfeeding experiences in women with preexisting type 2 diabetes mellitus from Thailand. A convergent parallel mixed-methods study will be conducted. Data will be collected from 20 pregnant women with preexisting type 2 diabetes mellitus in Thailand who are either primigravida or multigravida, aged 20-44 years old, speak the Thai language, and provide consent. The National Institute on Minority Health and Health Disparities Framework's sociocultural and behavioral domains guides the research aims. Data will be collected two times. The first time is during pregnancy (T1); study participants will complete questionnaires and engage in an interview about diabetes self-management, breastfeeding confidence, and breastfeeding intention. The second time is at 4-6 weeks postpartum (T2); study participants will be interviewed about their breastfeeding experiences. We will review and extract maternal health outcomes including body mass index, gestational weight gain, and glycated hemoglobin for T1 as well as fasting plasma glucose for T2. Qualitative data will be analyzed using directed content analysis. Quantitative data will be analyzed using descriptive statistics. Data sources will be triangulated with relative convergence in the results. This proposed study is significant because the findings will be used as a preliminary guide to developing a culturally tailored approach to enhance health outcomes of Thai women with diabetes in pregnancy and postpartum periods.

Prevalence and Predictive Factors for Exclusive Breastfeeding at Six Months among Thai Adolescent Mothers

Exclusive breastfeeding (EBF) in the first six months of life is the best and the most frequent choice for infants since it has important benefits for the infants and their mothers. However, the exclusive breastfeeding rate in Thailand remains low, especially among adolescent mothers. This predictive correlation study aimed to investigate factors predicting breastfeeding at six months among 253 Thai adolescent mothers from nine hospitals of the Bangkok Metropolitan Administration. Data were collected by using seven questionnaires: the Personal Characteristics, Pregnancy Intention and Breastfeeding Practice, Perceived Benefits of Breastfeeding, Perceived Barriers to Breastfeeding, Breastfeeding Self-Efficacy, Family Support, Maternity Care Practice, and Digital Technology Literacy Questionnaires. Data were analyzed by using descriptive statistics and logistic regression. The findings revealed that the prevalence of EBF at six months among Thai adolescent mothers was only 17.39%, and predictive factors were occupation (work/study) (p = 0.034), digital technology literacy (p < 0.001), family support (p = 0.021), pregnancy intention (p = 0.001), breastfeeding self-efficacy (p = 0.016), and perceived benefits of breastfeeding (p = 0.004). These factors could, together, predict the EBF rate at six months among Thai adolescent mothers in 42.2% (Nagelkerke R2 = 0.422) of the cases. These findings may help health professionals to develop activities and strategies for promoting exclusive breastfeeding by increasing breastfeeding self-efficacy, perceived benefits of breastfeeding, and family support, as well as improving digital technology skill among Thai adolescent mothers, especially student/employed adolescents who have unintended pregnancies.

Social Support for Breastfeeding Practice During the COVID-19 Second Wave in Thailand: A Cross-Sectional Study

BACKGROUND

Since December 2020, the second wave of COVID-19 in Thailand has had a considerable impact, and mothers have struggled to receive breastfeeding support in hospitals. In this situation, there has been limited research that addresses social support for breastfeeding and the influences of support in determining breastfeeding outcomes.

RESEARCH AIMS

(1) To describe the influence of COVID-19 on social support for breastfeeding and breastfeeding practices in the Thai context, and (2) to examine breastfeeding duration with different levels of social support from families and healthcare providers.

METHOD

This descriptive, cross-sectional online survey design was part of a larger multi-methods project about breastfeeding behaviors and experiences among postpartum mothers during the COVID-19 pandemic. Online questionnaires were administered from August to November 2021 to participants (N = 390) who were from three provinces in Thailand and had given birth 6-12 months prior to the survey.

RESULTS

Exclusive breastfeeding for 6 months was observed in less than half of the participants (n = 146, 37.4%). Perceptions of breastfeeding support were generally high overall among both family (Mdn = 45, IQR = 7) and healthcare providers (Mdn = 43, IQR = 7). Participants who perceived more breastfeeding support from families than the median had significantly longer exclusive breastfeeding durations than those who perceived less breastfeeding support than the median (z = -2.246, p = .025). The same pattern was present for breastfeeding support from healthcare providers (z = -2.380, p = 0.017).

CONCLUSIONS

While the exclusive breastfeeding rate was better than the pre-pandemic rate, successful breastfeeding was more common when participants perceived that they had received breastfeeding support. Policymakers should execute breastfeeding support systems along with COVID-19 management.

Amamentação na primeira hora de vida em município do interior do Rio de Janeiro: fatores associados

Resumo Objetivo analisar a amamentação na primeira hora de vida e os fatores associados em um município do interior do Rio de Janeiro. Método estudo online transversal, realizado entre maio de 2021 e agosto de 2022, com 97 parturientes do município de Rio das Ostras. Na associação entre variáveis, adotaram-se o Teste Qui-Quadrado e regressão logística. Resultados entre as participantes, 77,3% pariram na maternidade pública e 22,7% na maternidade privada. A prevalência da amamentação na primeira hora de vida na sala de parto e no alojamento conjunto foi, respectivamente, de 21,6% e 58,3%, com diferenças significativas entre as maternidades. Puérperas da maternidade pública tiveram mais chances de não amamentar na primeira hora de vida. Ter ensino básico aumentou as chances de o bebê não ser amamentado na sala de parto e não realizar contato pele a pele precoce, além de não ser amamentado no alojamento conjunto. Conclusão e implicações para a prática a amamentação na primeira hora de vida não atingiu níveis preconizados, e distintos fatores associados à sua ocorrência foram identificados, como nível de instrução, local do parto e contato pele a pele. Recomenda-se que maternidades implementem as práticas humanizadas no cuidado ao recém-nascido, para elevar as taxas da amamentação na primeira hora de vida.

Breastfeeding in the first hour of life in a city in the countryside of Rio de Janeiro: associated factors

Abstract Objective to analyze breastfeeding in the first hour of life and associated factors in a city in the countryside of Rio de Janeiro. Method a cross-sectional online study, carried out between May 2021 and August 2022, with 97 parturient women in the municipality of Rio das Ostras. In the association between variables, the chi-square test and logistic regression were used. Results among the participants, 77.3% gave birth in the public maternity hospital and 22.7% in the private maternity hospital. The prevalence of breastfeeding in the first hour of life in the delivery room and in rooming-in was, respectively, 21.6% and 58.3%, with significant differences between maternity hospitals. Postpartum women from the public maternity hospital were more likely to not breastfeed in the first hour of life. Having basic education increased the chances of the baby not being breastfed in the delivery room and not having early skin-to-skin contact and not breastfeeding breastfed in rooming-in. Conclusion and implications for practice breastfeeding in the first hour of life did not reach recommended levels and different factors associated with its occurrence were identified, such as education level, place of childbirth and skin-to-skin contact. It is recommended that maternity hospitals implement humanized practices in newborn care to increase breastfeeding rates in the first hour of life.

Cross-cultural adaptation and content validation of the Infant Feeding Intentions Scale for Thai pregnant women

This study aimed to validate a translated and culturally adapted version of the Infant Feeding Intentions (IFI) Scale for use in Thailand. Prenatal breastfeeding intention is a strong indicator of breastfeeding initiation. The stronger the intention to breastfeed among pregnant women, the more likely breastfeeding will be initiated after childbirth and continue for an extended period. There are currently no IFI scales that have been validated for use in Thailand. The translation of the IFI scale from English to Thai was conducted through a six-stage approach that included initial translation, synthesis of translations, back-translation, expert committee review for content validity, reliability testing, and submission of the translated IFI to notify the scale developers. Both Item and Scale Content Validity Indices equaled 1, scored by five experts, who also validated the content for cross-cultural adaptation. The final Thai IFI (T-IFI) scale demonstrated high content validity. A total of 30 Thai pregnant women participated in the reliability testing. The Cronbach's alpha of the 5-item T-IFI scale was 0.857, which indicated satisfactory internal consistency. The T-IFI scale demonstrated high content validity and was culturally appropriate for use in a Thai-speaking population. It has potential to strengthen assessments of prenatal infant feeding intention among pregnant women in Thailand.

Effect of baby food marketing exposure on infant and young child feeding regimes in Bangkok, Thailand

Background

Baby food marketing undermines breastfeeding by influencing women’s attitudes and decision-making favourably toward commercial baby food. This study aimed to explore the effects of various baby food marketing techniques on Thai mothers’ opinions about commercial milk formulas (CMF) and commercial complementary foods (CCF) and their infant and young child feeding behaviours.

Methods

This study used a cross-sectional survey employing the World Health Organization (WHO) NetCode Toolkit Protocol for Periodic Assessment, and the United Nations International Children’s Emergency Fund (UNICEF) Multiple Indicator Cluster Survey to collect data on mothers’ experience with and their opinion on the various types of marketing of CMF and CCF, and their feeding behaviour. Data collection used structured interviews of mothers with children aged two years or below attending 33 health facilities in Bangkok. Univariable and multivariable regression analysis then investigated links between mothers’ reported exposure to baby food marketing and their infant and young child feeding behaviours, employing a semantic scale and considering key sociodemographic and other variables.

Results

Three hundred and thirty mothers were surveyed in Bangkok. Around 90% reported experiencing exposure to at least one type of baby food marketing during the previous six months, mostly from electronic media. More than half of the women had positive opinions of CMF. Virtually all children had been breastfed initially, but 74.6% were given CMF and 72.8% stopped breastfeeding before six months. Multivariable analysis showed that mothers who lived in a couple were significantly less likely to favour CMF, and mothers in middle-income households and those who had received advice about CMF from others were more likely to have a favourable opinion. Mothers in formal employment were over six times more likely to feed formula than those not in employment. Women who experienced baby food marketing at health facilities were four times more likely to feed CMF to their children than those not experiencing such marketing.

Conclusions

Specific types of baby food marketing were strongly linked to mothers’ opinions on and use of CMF in Bangkok, Thailand. It is recommended that breastfeeding policies in health facilities and employment are fully implemented and enforced.

Bristol Breastfeeding Assessment Tool-Thai Version: Translation, Validity, and Reliability

BACKGROUND

In 2019, 14.0% of infants in Thailand were exclusively breastfed up to 6 months of age. To increase exclusive breastfeeding, an objective assessment measure would be useful to maternity care providers for appraising the problems encountered by new mothers' experiences with breastfeeding.

RESEARCH AIMS

To translate the Bristol Breastfeeding Assessment Tool from English into Thai; to assess the reliability and validity of the Thai Bristol Breastfeeding Assessment Tool; and to explore the relationship of a mother's self-efficacy to successful breastfeeding.

METHODS

Using a methodological design, we purposively sampled 302 new mothers from two tertiary hospitals in Thailand who had given birth to a single baby with an uncomplicated vaginal birth. The Thai Bristol Breastfeeding Assessment Tool's structure was examined using confirmatory factor analysis. Concurrent and convergent validity were assessed using the Thai LATCH instrument and Thai Breastfeeding Self-Efficacy Scale, respectively.

RESULTS

The inter-item Thai Bristol Breastfeeding Assessment Tool correlation coefficients were positive and strong. The correlation between scores of the Thai Bristol Breastfeeding Assessment Tool and Thai LATCH instrument were positive and strong and had acceptable concurrent validity. The confirmatory factor analysis model fit the Thai Bristol Breastfeeding Assessment Tool data perfectly and the Cronbach's alpha coefficient had acceptable internal reliability.

CONCLUSIONS

The Thai Bristol Breastfeeding Assessment Tool is a cross-culturally translated instrument equivalent to its English version and demonstrated acceptable validity and reliability. The instrument provides a mechanism for an objective assessment and monitoring system of optimal breastfeeding practices in Thai mothers with newborns.

A rapid rise in hormone receptor-positive and HER2-positive breast cancer subtypes in Southern Thai women: A population-based study in Songkhla

The incidence of breast cancer is increasing in low- and middle-income countries, including Thailand. However, its molecular immunohistochemical (M-IHC) subtypes have not been summarized in a population-based cancer registry. Thus, we aimed to estimate the breast cancer incidence and trends based on the hormone receptor and human epidermal growth factor receptor 2 (HER2) status. This cross-sectional study included 2,883 women diagnosed with primary invasive breast cancer between 2009 and 2018 from the Songkhla Cancer Registry. After imputing the missing values of estrogen receptor (ER), progesterone receptor (PR), and HER2 status, the cases were classified into four subtypes: HR+/HER2-, HR+/HER2+, HR-/HER2-, and HR-/HER2+. The age-specific incidence rate of 5-year age groups and age-standardized incidence rate (ASR) were calculated. An age-period-cohort (APC) model was used to describe the effects of age, birth cohort, and period of diagnosis. Finally, the incidence trends were extrapolated to 2030 based on the APC and joinpoint models. The results showed, HR+/HER2- had the highest ASR in breast cancer. The incidence trends of HR+/HER2- and HR+/HER2+ increased with an annual percent change of 5.4% (95%CI: 2.5% to 8.3%) and 10.1% (95%CI: 4.9% to 15.5%), respectively. The rate ratio was high in the younger generation and recent period of diagnosis. The joinpoint and APC model projections showed that the ASR of HR+/HER2- would reach 30.0 and 29.2 cases per 100,000 women, while ASR of the HR+/HER2+ would reach 8.8 and 10.4 cases per 100,000 women in 2030. On the other hand, the incidence trends of the HR-/HER2- and HR-/HER2+ subtypes were stable. The rising trends of HR-positive and a part of HER2-positive breast cancer forecast a dynamicity of the future health care budgeting, resource allocation, and provision of facilities.

Tailoring an online breastfeeding course for Southeast Asian paediatric trainees- A qualitative study of user experience from Malaysia and Thailand

BACKGROUND

This study explored the user experiences of paediatric postgraduate trainees in Malaysia and Thailand in using a 2 h and 15 min online module for breastfeeding developed for Southeast Asia, which was adapted from existing European online modules for European and German Continuing Medical Education (CME) credits.

METHODS

A qualitative study using focus group discussions (FGDs) was conducted with paediatric postgraduate trainees who used an online English-language breastfeeding module in two Thai universities (May 2020, done online) and two Malaysian universities (Sept- Nov 2019, in-person). FGDs explored module usability and utility. Sessions were transcribed verbatim and analysed thematically. The process of coding was done collaboratively by Thai and Malaysian researchers.

RESULTS

Twenty Six resident trainees participated (Thai, n = 13; Malaysian, n = 13). Ages ranged from 29-34 years old, with 21 females. Nineteen participants had never used online learning modules prior to this. Participants took between 1 to 5 sessions to complete the breastfeeding module. Four themes emerged from their experience. 1) The online learning module was more engaging and detailed than previous lectures, courses and/or books, but lacked hands-on training. 2) Using an online platform facilitated learning as eased navigation and resource searching, however, problems were encountered navigating the module on some devices. 3) Learners preferred less words and more graphics, as this helped them capture key messages. 4) Regionally tailored content elicited a mixed reaction from participants.

CONCLUSIONS

Users found that the adapted module compared favourably with previous learning experiences. However, online learning modules lack hands-on training, and implementation should ideally incorporate a mix of both. Consideration of device diversity and preferences for how content was adapted for local settings are needed for tailoring.

Exclusive Breastfeeding Experiences of Thai Mothers in Metropolitan Bangkok

Introduction

In 2019, only 14% of mothers in Thailand performed six-month exclusive breastfeeding. This study sought to understand the pathways that mothers in Bangkok Metropolitan took to achieve successful six-month exclusive breastfeeding.

Methods

A total of 50 mothers living in Bangkok with children aged 6–12 months, who achieved and not achieved 6-month exclusive breastfeeding, were recruited for in-depth interviews during February to July 2020. Inductive thematic analysis of participants’ viewpoints was applied for data analysis and interpretation.

Results

Four themes that contributed to six-month exclusive breastfeeding were i)  maternal breastfeeding self-efficacy;  ii)  support provided by family members;  iii)  engagement with and support from healthcare professionals; and iv)  employers’ support and workplace environments. Mothers with strong breastfeeding intentions and “perceived capability” to succeed at breastfeeding tended to prioritize breastfeeding and overcome and cope well with unforeseen breastfeeding challenges. Supportive family members, who were convinced of the benefits of breastfeeding, engaged in maternal decision-making, and provided optimal support, contributed to successful exclusive breastfeeding. Health professionals were key in supporting mothers throughout pregnancy until the postpartum period. Lactating-mother-friendly working conditions, flexible working hours and enabling workplace environments, including the provision of breastfeeding breaks and a dedicate space for breast milk expression, were enabling factors for successful exclusive breastfeeding among working mothers.

Conclusion

We recommend that all mothers and their family members are fully informed and convinced of the benefit from breastfeeding and trained with practical skill during their visit to antenatal care clinics. These interventions aim to develop mothers’ self-efficacy for breastfeeding and to prepare them to manage common breastfeeding challenges. Health professionals should provide regular follow-up and counseling sessions on breastfeeding practices to mothers and families throughout the lactating period, especially working mothers for breastfeeding continuation after resume to work. Enhanced societal collective actions such as breastfeeding-friendly policy in workplace, including breastfeeding break-time and corner, can create enabling environments for successful exclusive breastfeeding.

Maternal Mental Health under COVID-19 Pandemic in Thailand

Numerous nations have implemented lockdown measures in response to the COVID-19 pandemic. As a consequence of the lockdown on daily living, social participation, and health service accessibility, vulnerable people, for example, new mothers, may experience an increase in mental health problems. This cross-sectional survey was conducted to investigate the impact of the COVID-19 pandemic lockdown on Thai new mothers and the variables affecting their mental health. The survey data were collected from 903 Thai mothers with infants aged 0-12 months using an online platform and a face-to-face interview questionnaire survey between 17 July and 17 October 2020, during the first nationwide COVID-19 lockdown period. For the final analysis, there were 862 participants who completed all of the questions. The full exploratory analysis was performed by multivariable linear regression to identify the variables influencing maternal mental health. Our study demonstrated that new mothers reported feeling a high extent to some extent of worry (44.9%), increased appetite (40.4%), becoming easily annoyed or irritable (39.1%), and feeling down (33.5%), whereas 82.7% felt able to cope with the first lockdown situation. Practiced relaxation techniques were associated with positive maternal mental health (adjusted β = 1.05, 95% CI 0.57 to 1.52, p < 0.001). The perceived impact of the COVID-19 lockdown was on the household's ability to pay for rent, to make mortgage payments (adjusted β = -1.59, 95% CI -2.87 to -0.36, p = 0.011), the household's ability to pay for other essentials, such as utilities and medication (adjusted β = -1.99, 95% CI -3.16 to -0.81, p = 0.001), household crowding after lockdown (adjusted β = -3.46, 95% CI -4.86 to -2.06, p < 0.001), and not going outside or doing outdoor activities (adjusted β = -2.22, 95% CI -3.35 to -1.08, p < 0.001). These impacts were significantly associated with negative mental health. In conclusion, our results emphasize the critical need for continuous monitoring of maternal mental health and developing an effective response strategy and activity for promoting maternal mental health under the stress of repetitive lockdowns and increased economic pressures.

Factors Associated with the Maintenance of Breastfeeding at One Year among Women in Chiang Mai, Thailand

This study aimed to investigate factors associated with breastfeeding for at least one year among women in Chiang Mai, Thailand. We conducted a cross-sectional study of 451 mothers with children aged between 12 and 24 months who visited the well-baby clinic among women who visited the well-baby clinic in secondary and tertiary hospitals. The data collected included maternal sociodemographic information, employment status, reasons contributing to continued breastfeeding, primary sources of information, and influential people affecting continued breastfeeding. Multivariable logistic regression analysis was used to investigate the relationship between explanatory variables and continued breastfeeding at one year. Reporting "easier to bond with baby" as a reason to continue breastfeeding (AOR 3.118, 95% CI: 2.022, 4.809) and multiparous status (AOR 1.588, 95% CI: 1.042, 2.420) were positive predictors of mothers who had breastfeeding at least one year postpartum while mothers with undergraduate education level (AOR 0.635, 95% CI: 0.404, 0.997) were more likely to discontinue breastfeeding. Our study highlighted that working mothers have lower odds of continued breastfeeding than stay-at-home mothers (SAHMs), which was found for work with day shifts (AOR 0.437, 95% CI: 0.261, 0.731), work with rotational shifts (AOR 0.481, 95% CI: 0.247, 0.934), and work from home jobs with a flexible schedule (AOR 0.439, 95% CI: 0.229, 0.838). These findings showed that both employment outside home and work from home were strong risk factors for discontinuing breastfeeding before 12 months. We suggest that a breastfeeding-friendly workplace policy is essential to enhance the continuance of breastfeeding. Additionally, working at home requires more research to explore breastfeeding barriers and establish more support strategies.

Breastfeeding Practice and Association between Characteristics and Experiences of Mothers Living in Bangkok

Although the benefits of breastfeeding are widely recognized, only 14% of mothers in Thailand exclusively breastfed their children during the first six months of their lives in 2019, which dropped from 23% in 2016. This study aimed to assess the prevalence of exclusive breastfeeding (EBF) up to six months, current breastfeeding patterns, and key determinants that influence six-month EBF among mothers residing in Bangkok, Thailand. A cross-sectional study was conducted using a self-administered questionnaire survey. In total, 676 healthy mothers living in Bangkok, whose most recent child was between 6 and 18 months old, were recruited. Descriptive statistics, univariable analysis by Chi-square test, and multivariable logistic regression were performed to assess the association between six-month EBF and maternal characteristics and experiences of using maternal health services. The prevalence of six-month EBF of infants in Bangkok was 41%. The key determinants that influenced six-month EBF included: maternal age of more than 30 years; higher education level; higher maternal income; multi-parity; exposure to breastfeeding advice during pregnancy; intention to breastfeed for a long duration (≥6 months) during pregnancy; experience of six-month EBF in the previous child. This study draws health professionals' and policy makers' attention to further promote breastfeeding in particular types of mothers.
