Doing the month: rickets and post-partum convalescence in rural China

Prevalence of Traditional Asian Postpartum Practices at a Federally Qualified Health Center

To evaluate the knowledge of, participation in, attitudes towards, and experiences with "doing the month" (DTM), a traditional Chinese and Vietnamese postpartum practice, at a federally qualified health center that serves predominantly Asian immigrants. DTM practices revolve around the balance between yin and yang and include practices such as the mother remaining on bed rest for as long as possible, restricting diet to certain foods, and avoiding visitors and social activities. A cross-sectional survey in Chinese, Vietnamese, and English was developed to determine the prevalence of women who have heard of and participated in DTM. 154 respondents participated. The mean age of respondents was 40.1 years. Without prompting of what DTM was, 58 (37.7%) responded that they had heard of DTM. After an explanatory paragraph, this increased to 117 (76.6%) participants. Out of 107 patients who have children, 65 (60.7%) "did the month" after giving birth. Participation rates were highest for women who identified as Chinese or Vietnamese. Likert-type scale questions showed that respondents believed DTM was stressful but enjoyable and helpful for recovery from childbirth. In conclusion, DTM is a common practice that health providers should be aware of.

Natural sunlight plus vitamin D supplementation ameliorate delayed early motor development in newborn infants from maternal perinatal depression

BACKGROUND

Increased cortisol has been shown to be negatively correlated with infant motor development. Sunlight help decrease the level of cortisol. Vitamin D is associated with infant motor development. The present study aimed to determine whether natural sunlight exposure plus vitamin D supplements could ameliorate delayed early motor development in little infants from maternal perinatal depression.

METHODS

The term pregnant women waiting for delivery from the department of gynecology and obstetrics were assessed depressive symptoms by Hamilton Rating Scale for Depression (HAMD). 120 normal and 229 depressed subjects were recruited. During 2 days postpartum, infant motor development were assessed by Neonatal Behavioral Assessment Scale (NBAS). Infants of 2-day-old in maternal depression group were divided into four groups: control group, conventional vitamin D supplements (400IU/d) group, high dose of vitamin D supplements group (1000IU/d), sunlight plus conventional vitamin D supplement group (400IU/d). Serum and hair cortisol (HairF) in mothers and infants were measured.

RESULTS

The infants of perinatal depressed mothers displayed early motor developmental delay accompanied by increased cortisol. Sunlight plus conventional vitamin D supplement (400IU/d) were better than exclusive vitamin D supplements for the amelioration delayed early motor development in infants (p < 0.05). The infants exposure to sunlight 7-14 h/week plus conventional vitamin D supplement reached the best scores of motor development and the lowest HairF (p < 0.05).

LIMITATIONS

We should have measured the serum 25OH-vitamin D concentrations.

CONCLUSIONS

Sunlight plus vitamin D supplements could ameliorate delayed early motor development in little infants by decreasing cortisol from perinatal depression.

"Doing the month" and postpartum depression among Chinese women: A Shanghai prospective cohort study

BACKGROUND

The Chinese postpartum custom of "doing the month" characterized by generous social support available through the traditional cultural practices was considered to protect women from postpartum depression in early puerperium.

METHODS

This study used data from the Shanghai Birth Cohort, a study of 2615 postpartum women from Shanghai, China, that was conducted between 2013 and 2016. Detailed information on the traditional "doing the month" practices and the on the Edinburgh Postnatal Depression Scale scores was collected from questionnaires administered on the 42nd day after childbirth. Logistic regression models were used to examine the association between the adopting traditional puerperium practices and postpartum depression.

RESULTS

The estimated prevalence of postpartum depression in women from the Shanghai area in China was 11.8% (n = 308) at six weeks postpartum. Women who went outside their homes during the first month postpartum showed higher risks of postpartum depression compared with those who never left the house (1-2 times: OR = 1.9, 95% CI = 1.4-2.4; 3-5 times: OR = 2.3, 95% CI = 1.5-3.5; ≥6 times: OR = 2.5, 95% CI = 1.2-5.1). Women with average sleep of 6 h or less per night were more likely to suffer from postpartum depression compared with those who slept 8 h (6 h: OR = 1.7, 95% CI = 1.2-2.4; less than 6 h : OR = 3.3, 95% CI = 2.2-5.0). Women who opened the house windows most of the time exhibited decreased risks of postpartum depression compared to those who never or rarely opened the windows (often: OR = 0.6, 95% CI = 0.4-0.9; always: OR = 0.4, 95% CI = 0.3-0.7).

CONCLUSIONS

Our results suggested that not all the activities of "doing the month" provided protection against developing PPD. This study emphasized the need for flexibility to fit and adjust the ritual into the modern life to enhance the positive effects of traditional practices on maternal health.

Experiences of Chinese immigrant women following "Zuo Yue Zi" in British Columbia

AIMS AND OBJECTIVES

To describe Chinese women's experiences with "zuo yue zi" in British Columbia, Canada.

BACKGROUND

Women born in China and Taiwan are increasingly immigrating to westernised countries. Many women choose to follow traditional Chinese postpartum practices, also called "zuo yue zi." Few studies have examined women's use of traditional practices in western countries.

DESIGN

The study used a qualitative descriptive design.

METHODS

We recruited 13 mothers who were: aged 19 or older, immigrants from mainland China, Hong Kong or Taiwan in the last 5 years, and caring for infants born in the previous 6 weeks. Semistructured interviews were conducted in Mandarin, translated into English, transcribed and analysed using inductive content analysis.

RESULTS

The core theme was Chinese women's novel encounters with "zuo yue zi." The women's expectations of "zuo yue zi" were acquired through birth experiences or interactions with family and friends. The participants struggled with implementing traditional practices because social support and formal institutional structures were lacking. They modified their expectations about "zuo yue zi." Factors affecting their practices were catalysts and deterrents. Catalysts included help from Chinese family members, friends and informed healthcare providers. Deterrents included unregulated paid helpers, uninformed care providers, financial constraints and structural limitations in their new environments.

CONCLUSIONS

Chinese immigrant women struggled to modify and implement traditional practices in their adopted country when they encountered financial constraints, unregulated paid helpers and varying support from health care providers.

RELEVANCE TO CLINICAL PRACTICE

Some postpartum women following "zuo yue zi" believed that the practice would prevent chronic illness and strengthen their intrafamily relationships. Immigrant mothers require nursing support to follow traditional postpartum practices. Nurses can advocate on patients' behalf to increase care providers' knowledge about "zuo yue zi" and public awareness for necessary regulated institutional structures.

The care needs of postpartum women taking their first time of doing the month: a qualitative study

BACKGROUND

In contemporary Taiwan, after giving birth, many women undertake a traditional postpartum practice called 'doing the month', which occurs in the medical context of postpartum nursing centres instead of at home. Thus, healthcare workers must identify and address the care needs of new mothers in this setting to improve the care of new mothers and their baby and family.

AIM

To explore new mothers' care needs from their own perspectives during the period of doing the month.

METHODS

A qualitative study was performed. Eligible participants recruited through purposive sampling were interviewed comprehensively.

RESULTS

Twenty-seven primiparous women participated (mean age: 32 years; mean marriage length: 3.4 years). Four themes were identified: the need to increase energy to gain more yang force, the need to internalise mothering, the need to be supported by the family and friends, and the need to be understood.

CONCLUSIONS

For effective care, sufficient support and guidance must be provided to first-time mothers and their families, especially when mother-baby rooming-in is the standard of care.

Eating soup with nails of pig: thematic synthesis of the qualitative literature on cultural practices and beliefs influencing perinatal nutrition in low and middle income countries

BACKGROUND

The perinatal period, i.e. pregnancy, childbirth and early infancy, is a significant transition period where the biological and the social strongly intersect. In low and middle-income countries the disease burden arising from the perinatal period, is still substantial. The perinatal period is also a crucial window of opportunity for reducing undernutrition and its long term adverse effects.

METHODS

We explored qualitative research conducted in low resource settings around the perinatal continuum over the past two decades, with a particular focus on the 'cultural' realm, to identify common themes influencing maternal and infant nutrition. We systematically searched electronic databases from 1990 to 2014, including MEDLINE, EMBASE, PsycINFO, Scopus and Cumulative Index to Nursing and Allied Health Literature, using relevant search terms including traditional beliefs, practices, pregnancy, childbirth, developing countries etc. Adapted Consolidated Criteria for Reporting Qualitative Health Research and Critical Appraisal Skills Programme criteria were used to determine quality of studies. We synthesised the literature thematically, enabled by NVivo 10 software.

RESULTS

Most studies showed cultural support for breastfeeding, although most traditional societies delayed breastfeeding due to colostrum being considered 'dirty'. A range of restrictive practices through pregnancy and the post- partum period were revealed in Asia, Latin America and Africa. There was a strong cultural understanding of the healing power of everyday foods. A wide range of good foods and bad foods continued to have currency through the perinatal continuum, with little consensus between groups of what was beneficial versus harmful. Cross-cutting themes that emerged were 1) the role of the woman/mother/wife as strong and good; 2) poverty restricting women's nutrition choices; 3) change being constant, but the direction of change unpredictable.

CONCLUSIONS

A rich and diverse repertoire of cultural practices and beliefs influenced perinatal nutrition. Results from this synthesis should influence public health policymakers and practitioners, to tailor contextually specific, culturally responsive perinatal nutrition interventions to optimise health and wellbeing of mother-infant dyads. Ideally these interventions should build on culturally sanctioned life affirming behaviours such as breastfeeding, promoting post-partum rest and recovery, while modifying the potentially harmful aspects of other cultural practices in the perinatal period.

Sun exposure and vitamin D supplementation in relation to vitamin D status of breastfeeding mothers and infants in the global exploration of human milk study

Although vitamin D (vD) deficiency is common in breastfed infants and their mothers during pregnancy and lactation, a standardized global comparison is lacking. We studied the prevalence and risk factors for vD deficiency using a standardized protocol in a cohort of breastfeeding mother-infant pairs, enrolled in the Global Exploration of Human Milk Study, designed to examine longitudinally the effect of environment, diet and culture. Mothers planned to provide breast milk for at least three months post-partum and were enrolled at four weeks postpartum in Shanghai, China (n = 112), Cincinnati, Ohio (n = 119), and Mexico City, Mexico (n = 113). Maternal serum 25(OH)D was measured by radioimmunoassay (<50 nmol/L was categorized as deficient). Serum 25(OH)D was measured in a subset of infants (35 Shanghai, 47 Cincinnati and 45 Mexico City) seen at 26 weeks of age during fall and winter seasons. Data collected prospectively included vD supplementation, season and sun index (sun exposure × body surface area exposed while outdoors). Differences and factors associated with vD deficiency were evaluated using appropriate statistical analysis. vD deficiency in order of magnitude was identified in 62%, 52% and 17% of Mexican, Shanghai and Cincinnati mothers, respectively (p < 0.001). In regression analysis, vD supplementation (p < 0.01), obesity (p = 0.03), season (p = 0.001) and sites (p < 0.001) predicted maternal vD status. vD deficiency in order of  magnitude was found in 62%, 28%, and 6% of Mexican, Cincinnati and Shanghai infants, respectively (p < 0.001). Season (p = 0.022), adding formula feeding (p < 0.001) and a higher sun index (p = 0.085) predicted higher infant vD status. vD deficiency appears to be a global problem in mothers and infants, though the prevalence in diverse populations may depend upon sun exposure behaviors and vD supplementation. Greater attention to maternal and infant vD status starting during pregnancy is warranted worldwide.

Doing the month in a Taiwanese postpartum nursing center: an ethnographic study

Traditionally Chinese and Taiwanese postpartum women conducted postpartum ritual practices, called "doing the month," at home. Today, many Taiwanese women undertake this ritual in postpartum nursing centers. However, little is known about how the traditional practices are being transformed in relation to contemporary health care in Taiwan. In this ethnographic study observations were carried out in a large post-partum center attached to a major hospital in Taipei for nine months, and 27 postpartum women were interviewed. Data were analyzed using ethnographic approaches to extract codes and categories. Doing the month was reshaped by being relocated from the home to a healthcare setting. Midwives took on roles traditionally taken by family members, which had an impact on family roles and relationships. Some postpartum practices were maintained, based on traditional explanations. However, many were modified or challenged, based on explanations from contemporary scientific knowledge. Midwives need to be aware that there could be differences between their culture of care and the cultural values of the women they care for. This study informs culturally appropriate postpartum care and support for women with traditional and contemporary cultural beliefs and attitudes to doing the month in a range of healthcare contexts.

Effect of Postpartum Practices of Doing the Month on Chinese Women’s Physical and Psychological Health

The purpose of the study was to describe Chinese women’s postpartum physiological and psychological health and adherence to “doing-the-month” practices. A descriptive repeated measures design was used, with data collected at 3 days and 6 weeks postpartum. The convenience sample consisted of 198 healthy childbearing women with a term birth. Maternal physical health was measured by the Six-Minute Walk (endurance), Chair Stand test (muscle strength), severity of physical symptoms, and physical health subscales of SF36v2. Maternal psychological health was measured by the Edinburgh Postnatal Depression scale. Adherence was measured by the Adherence to Doing-the-Month Practices questionnaire. Aerobic endurance and lower-body muscle strength improved significantly across time ( p < .001) but remained suboptimal for maternal age. Women who delivered by Cesarean section had significantly poorer physical health than those who had a vaginal delivery. Physical functioning significantly increased, but general health and role limitations due to physical health significantly decreased over time. Postpartum physical symptoms decreased in number and severity. Depression increased over time ( p < .001). Adherence to doing the month was negatively correlated with aerobic endurance and positively correlated with depression at 6 weeks ( p < .05). These findings challenge the assumption that practices of doing the month are healthy for Chinese women’s recovery after childbirth. Research-based evidence needs to be integrated into doing-the-month practices. Education of Chinese women and families, whether living at home or abroad, is needed about the adverse health effects of doing the month. Routine screening for postpartum depression is also advised.

Maternal vitamin D status: implications for the development of infantile nutritional rickets

The mother is the major source of circulating 25-OHD concentrations in the young infant. Thus maternal vitamin D status is an important factor in determining the vitamin D status of the infant and their risk of developing vitamin D deficiency and infantile nutritional rickets. As a result, breastfed infants of mothers with vitamin D deficiency who are unsupplemented and who receive little sunlight exposure are at high risk of developing vitamin D deficiency or rickets. Despite food fortification policies in many countries and recommendations for vitamin D supplementation of at-risk groups, vitamin D deficiency and infantile rickets remain major public health challenges in many developed and developing countries. There is evidence that the current supplementation recommendations, particularly for pregnant and lactating women, are inadequate to ensure vitamin D sufficiency in these groups. A widespread and concerted effort is needed to ensure daily supplementation of breastfed and other infants at high risk with vitamin D 400 IU from birth and pregnant women in high risk communities with at least 600 IU; awareness needs to be developed among the public and medical practitioners of the urgent need to improve the vitamin D status of pregnant and lactating mothers and their infants. Further studies are required to determine the optimal doses of vitamin D supplementation in pregnancy and during lactation, and for normalizing vitamin D stores in infancy to reduce the prevalence of infantile nutritional rickets. Operational research studies also need to be conducted to understand the best methods of implementing supplementation programs and the factors that are likely to impede their success.

The Association between Traditional Chinese Dietary and Herbal Therapies and Uterine Involution in Postpartum Women

Background. Traditional Chinese postpartum care is believed to help in the recovery of women after delivery. Objective. This study investigated the association of elements in dietary and herbal therapy with uterine involution. Methods. Indices of uterine involution were measured ultrasonographically in 127 postpartum women between 4-6 weeks after delivery. A self-reported retrospective questionnaire was used to query women about their frequencies of taking herbal medicines and consuming special diets during the first month after delivery. Correlation coefficients were calculated to identify the associations, then the regression models were used to identify the predictors. Result. Among the herbal medicines and diet, consumption of Eucommia ulmoides (E. ulmoides) negatively correlated with the AP diameter of the uterus and the cavity. E. ulmoides was also the only predictor of maximum AP diameter of the uterus, AP diameter of the uterus 5 cm from the fundus, and the maximum AP diameter of the cavity. Moreover, consumption of Sheng-hau-tang was significantly correlated with anteverted uterus and was a predictor of anteverted uterus. Conclusion. E. ulmoides and Sheng-hau-tang positively correlated with the degree of uterine involution after delivery, implying that both therapies might possess the pharmacological efficacy of uterine contraction in postpartum women.

Optimal vitamin A and suboptimal vitamin D status are common in Iranian infants

AIM

Investigation of serum concentrations of vitamins A and D in Iranian infants.

METHODS

A descriptive cross-sectional study, investigating 7112 infants (15-23 months of age) from all regions of Iran, who attended health care centres from May 25 to June 2, 2001. Unequal clusters with unequal household sizes were sampled. Vitamin A and D levels were analysed with high-performance liquid chromatography.

RESULTS

The mean (SD) concentration of vitamin A was 2.09 (0.83) μmol/L. At a national level, 0.7% of the infants had a level indicating deficiency, and 0.5% of the infants had insufficient concentrations of vitamin A, defined as serum concentrations <0.35 and <0.7 μmol/L retinol, respectively. A total of 88% of infants had optimal concentrations (>1.4 μmol/L). The mean (SD) concentration of vitamin D was 61.3 (31.4) nmol/L. Deficiency was found in 2.8% of infants (<25 nmol/L), and insufficiency in 32.9% (<50 nmol/L). Suboptimal and optimal concentrations were found in 44% and 20%, representing 50-75 and >75 nmol/L, respectively. Girls had lower vitamin D concentrations than boys (p = 0.006).

CONCLUSION

As in developed countries, vitamin A deficiency was rare in Iranian infants. Vitamin D deficiency was also rare, but 33% of infants had insufficient levels; this was more common in girls than boys.

Maternal vitamin D status: implications for the development of infantile nutritional rickets

The mother is the major source of circulating 25-hydroxyvitamin D concentration in the young infant. Maternal vitamin D status is an important factor in determining the vitamin D status of the infant and their risk of developing vitamin D deficiency and infantile nutritional rickets. There is evidence that the current supplementation recommendations, particularly for pregnant and lactating women, are inadequate to ensure vitamin D sufficiency in these groups. A widespread and concerted effort is needed to ensure daily supplementation of breastfed and other infants at high risk with vitamin D 400 IU from birth and of pregnant women in high-risk communities with 2000 IU. Future studies are required to determine the optimal doses of vitamin D supplementation in pregnancy and during lactation, and for normalizing vitamin D stores in infancy to reduce the prevalence of infantile nutritional rickets. Operational research studies are needed to understand the best methods of implementing supplementation programs and the factors that are likely to impede their success.
