STUDY QUESTION Is the mode of conception (natural, subfertility and non-IVF, and IVF) associated with the risk of Type 1 diabetes mellitus among offspring? SUMMARY ANSWER The risk of Type 1 diabetes in offspring does not differ among natural, subfertility and non-IVF, and IVF conceptions. WHAT IS KNOWN ALREADY Evidence has shown that children born through IVF have an increased risk of impaired metabolic function. STUDY DESIGN, SIZE, DURATION A population-based, nested case–control study was carried out, including 769 children with and 3110 children without Type 1 diabetes mellitus within the prospective cohort of 2 228 073 eligible parent-child triads between 1 January 2004 and 31 December 2017. PARTICIPANTS/MATERIALS, SETTING, METHODS Using registry data from Taiwan, the mode of conception was divided into three categories: natural conception, subfertility, and non-IVF (indicating infertility diagnosis but no IVF-facilitated conception), and IVF conception. The diagnosis of Type 1 diabetes mellitus was determined according to the International Classification of Diseases, 9th or 10th Revision, Clinical Modification. Each case was matched to four controls randomly selected after matching for child age and sex, residential township, and calendar date of Type 1 diabetes mellitus occurrence. MAIN RESULTS AND THE ROLE OF CHANCE Based on 14.3 million person-years of follow-up (median, 10 years), the incidence rates of Type 1 diabetes were 5.33, 5.61, and 4.74 per 100 000 person-years for natural, subfertility and non-IVF, and IVF conceptions, respectively. Compared with natural conception, no significant differences in the risk of Type 1 diabetes were observed for subfertility and non-IVF conception (adjusted odds ratio, 1.04 [95% CI, 0.85–1.27]) and IVF conception (adjusted odds ratio, 1.00 [95% CI, 0.50–2.03]). In addition, there were no significant differences in the risk of Type 1 diabetes according to infertility source (male/female/both) and embryo type (fresh/frozen). LIMITATIONS, REASONS FOR CAUTION Although the population-level data from Taiwanese registries was used, a limited number of exposed cases was included. We showed risk of Type 1 diabetes was not associated with infertility source or embryo type; however, caution with interpretation is required owing to the limited number of exposed events after the stratification. The exclusion criterion regarding parents' history of diabetes mellitus was only applicable after 1997, and this might have caused residual confounding. WIDER IMPLICATIONS OF THE FINDINGS It has been reported that children born to parents who conceived through IVF had worse metabolic profiles than those who conceived naturally. Considering the findings of the present and previous studies, poor metabolic profiles may not be sufficient to develop Type 1 diabetes mellitus during childhood.

Objectives American Institute of Medicine (IOM) recommends different ranges of gestational weight gain (GWG) based on pre-pregnancy body mass index (BMI). In Taiwan, IOM guidelines are implemented concurrently with the local recommendation for GWG (10-14 kg). This study compared between the two sets of guidelines in relation to adverse perinatal outcomes. Methods We analyzed 31,653 primiparas with singletons from 2011 to 2016 annual National Breastfeeding Surveys. Logistic regressions for preterm birth, small for gestational age (SGA), large for gestational age (LGA), cesarean section and excessive postpartum weight retention (EPWR) were fitted separately for GWG categorized according to IOM and Taiwan ranges. Areas under the receiver-operator curves (AUC) and the predicted probabilities for each outcome were compared in each BMI group. Results AUC for both guidelines ranged within 0.51-0.73. Compared to Taiwan recommendation, IOM ranges showed lower probabilities of SGA for underweight (0.11-0.15 versus 0.14-0.18), of LGA for obese (0.12-0.15 versus 0.15-0.18), of EPWR for overweight (0.19-0.30 versus 0.27-0.39), and obese (0.15-0.22 versus 0.25-0.36); and higher probabilities of EPWR for underweight (0.17-0.33 versus 0.14-0.22). Conclusions for practice Discriminative performance of IOM and Taiwan recommendations was poor for the five adverse birth outcomes, and no preference for either set of recommendations could be inferred from our results. In the absence of specific GWG guidelines, health care workers may provide inconsistent information to their patients. Future research is needed to explore optimal GWG ranges that can reliably predict locally relevant perinatal outcomes for mother and child., Author(s): Alexander Waits [sup.1] [sup.2] , Chao-Yu Guo [sup.1] , Li-Yin Chien [sup.3] Author Affiliations: (1) grid.260539.b, 0000 0001 2059 7017, Institute of Public Health, National Yang Ming Chiao Tung [...]

Globally, there has been little growth in vaccination coverage, with countries in the Horn of Africa having the lowest vaccination rates. This study investigated factors associated with vaccination status among children under five years old in Somaliland. The 2020 Somaliland Demographic and Health Survey surveyed women aged 15–49 years from randomly selected households. This multilevel analysis included 2673 primary caregivers of children under five. Only 34% of children were ever vaccinated. Childhood vaccination coverage was positively associated with high-budget regions, high healthcare facility density, and children older than 23 months. Vaccination coverage was greater for urban and rural residents than for nomadic people. Children whose mothers could read part of one sentence or one complete sentence were more likely to be vaccinated than illiterate mothers. Children whose mothers received antenatal care (ANC) once, two to three times, or four times or more were more likely to be vaccinated than those whose mothers received no ANC. Childhood vaccination coverage in Somaliland is low. Promoting maternal ANC visits and increasing women's literacy may enhance vaccination coverage. Funds should be allocated to areas with low resources, particularly for nomadic people, to boost vaccination uptake. [ABSTRACT FROM AUTHOR]

Many studies have reported positive contributions of health promotion on the health behavior of nursing staff working in hospitals, including the maintenance of a regular healthy diet, engagement in physical activity, performance of routine screening practices, and participation in a health examination. Despite being considered a role model for healthy lifestyles, little is known about the effect of health-promoting hospital settings on nursing staff. The aim of this study was to perform a nationwide, hospital-based, cross-sectional, survey comparing health practices between full-time nurses of health-promoting hospitals and those of non-health-promoting hospitals in Taiwan. We conducted a nationwide, hospital-based, cross-sectional, survey in 100 hospitals from May to July 2011 using a questionnaire as the measurement tool. Nurses aged between 18 and 65 years from certified health-promoting hospitals (n = 14,769) were compared with nurses in non-health-promoting hospitals (n = 11,242). A multiple logistic regression model was conducted to estimate the effect of certified HPH status on the likelihood of performing health behavior, receiving general physical examination, undergoing cancer screening, and participating in hospital-based health-promoting activities. All nurses of HPH hospitals were more likely to perform physical activity, practice cancer screening, receive at least one general physical examination in the past 3 years, and had a higher chance of participating in at least one hospital-based health-promoting activity in the past year (particularly weight-control groups and sports-related clubs) than those of non-HPH hospitals. This study suggests the effectiveness of implementing health promotion on the health behavior of full-time nursing staff in hospitals. [ABSTRACT FROM AUTHOR]

Background: Drug use has been noted among students in Taiwan during the past decade and schools have a role in preventing or delaying students' drug use. We developed and evaluated a school-based, drug-use prevention program integrating the theory of planned behavior (TPB) and life skills for junior high school students. Methods: We recruited 441 seventh graders from randomly selected schools: N = 143 experimental groups, N = 142 conventional groups, and N = 156 control groups. The experimental group received ten 45-minute sessions of theory-based interventions. The conventional group got traditional didactic teaching and drug refusal skills. The control group received no intervention. Results: Compared to the control group, experimental group students showed greater improvement in attitude, subjective norm, perceived behavioral control, life skills, and intention not to use drugs. Compared to the conventional group, the experimental group had significantly higher posttest scores for 4 of the 5 outcomes, including life skills (96.53 vs. 90.92, p less than 0.001), attitude (27.43 vs. 24.40, p = 0.012), subjective norm (29.51 vs. 28.06, p = 0.002), and perceived behavioral control (18.59 vs. 16.81, p less than 0.001). The conventional group scored significantly higher in behavioral intention than did the control group. Conclusion: Study results demonstrated the effectiveness of a drug-use prevention program integrating the TPB and life skills. (Contains 5 tables.)

Associations between breastfeeding intention, duration and post‐natal depression (PND) have been shown in pre‐COVID‐19 studies. However, studies during COVID‐19 have not examined the associations between breastfeeding intention, breastfeeding practices, and PND in an international sample of post‐natal women, taking into consideration COVID‐19 related factors. This is the first study to address this gap as both PND and breastfeeding may be affected by COVID‐19, and have important long‐term effects on women's and infant's health. A cross‐sectional internet‐based survey was conducted with 3253 post‐natal women from five countries: Brazil, South Korea, Taiwan, Thailand, and the United Kingdom from July to November 2021. The results showed that women who intended to breastfeed during pregnancy had lower odds of having PND than women who did not intend to. Women who had no breastfeeding intention but actually breastfed had greater odds (AOR 1.75) of having PND than women who intended to breastfeed and actually breastfed. While there was no statistical significance in expressed breast milk feeding in multivariable logistic regression models, women who had shorter duration of breastfeeding directly on breast than they planned had greater odds (AOR 1.58) of having PND than those who breastfed longer than they planned even after adjusting for covariates including COVID‐19‐related variables. These findings suggested the importance of working with women on their breastfeeding intention. Tailored support is required to ensure women's breastfeeding needs are met and at the same time care for maternal mental health during and beyond the pandemic. Key messages: This study identified independent associations of breastfeeding intention and actual breastfeeding practices with PND after adjustment for COVID‐19‐related covariates.Although women who intended to breastfeed during pregnancy were less likely to have PND, those who did not intend to breastfeed but did breastfeed were more likely to have PND than those who intended to breastfeed and breastfed.Women with shorter (vs. longer) than planned duration of breastfeeding on breast were more likely to have PND.Health care providers and policymakers should ensure tailored support is available for women's infant feeding plans and mental health.

Studies regarding the impact of COVID-19 on breastfeeding have mostly used single- country samples or a qualitative design. The objective of this study was to examine breastfeeding intention during pregnancy and breastfeeding behaviour among postpartum women in five countries during the COVID-19 pandemic and the associated factors. An online questionnaire survey was conducted in Thailand, the United Kingdom, South Korea, Taiwan, and Brazil from July through November 2021. The study participants included 3253 mothers within six months of birth. About 90% of participants intended to breastfeed during pregnancy and 85.7% reported breastfeeding in the past 24 h. More than half reported their breastfeeding duration being as planned or longer despite COVID-19. Multivariate logistic regression models showed that being multiparous, ever tested COVID-19 positive, and having positive breastfeeding beliefs were associated with increased odds for intention to breastfeed during pregnancy. Lower maternal educational level, being primiparous, ever tested COVID-19 positive, and experiencing food insecurity were associated with decreased odds for breastfeeding duration being as planned or longer. Vaginal birth, currently working or on maternity leave, breastfeeding beliefs, breastfeeding support from spouse/partner/friend/relative, online support groups, and in-person or telephone contact with healthcare professionals were associated with increased odds for breastfeeding duration being as planned or longer. Breastfeeding intention and behaviour remained high during the COVID-19 pandemic. Online support groups and telephone contact with health professionals were effective during the pandemic.

Design: This study applied a cross‐sectional, descriptive correlational design. Aims and objectives: The purpose of the study was to examine the relationship between cognitive function and self‐reported antihypertensive medication adherence in middle‐aged and older hypertensive women. Background: Although medication adherence is an essential key for preventing complications from hypertension, poor medication adherence is common among middle‐aged and older hypertensive women. Taking medications involves a cognitive process. Little is known about the contribution of cognitive function to adherence to antihypertensive medication in middle‐aged and older women. Methods: This study used a convenience sample of 137 women aged ≥50 years recruited from a medical centre in southern Taiwan. Participants completed a survey of demographic and clinical information and self‐reported medication adherence, and received cognitive function tests. Hierarchical regression analyses were used to evaluate the association between cognitive function and medication adherence. This study followed the STROBE guidelines. Results: More than one‐fourth of the women (27%) reported poor adherence. Women with poor adherence appeared to have a significantly lower memory than women with good adherence. Memory was positively associated with antihypertensive medication adherence after controlling for age, blood pressure and duration of hypertension. Working memory, executive function and psychomotor speed were not significantly related to antihypertensive medication adherence. Conclusions: Reduced memory function was associated with poorer antihypertensive medication adherence among middle‐aged and older women. Middle‐aged and older women with hypertension and poor memory performance are at risk of poor medication adherence. Future prospective studies examining the causal relationship between cognitive function and antihypertensive medication adherence are warranted. Relevance to clinical practice: Nurses could evaluate the memory of middle‐aged and older hypertensive women when assessing antihypertensive medication adherence in clinical practice and provide relevant interventions.

Background: Hypertension is prevalent in older women and is associated with increased cognitive impairment. Exercise has demonstrated beneficial effects on cognitive function, but the impact of exercise on older hypertensive women remains unclear. We investigated the effects of an aerobic walking program on memory, subjective cognitive complaints, and brain-derived neurotrophic factor in older hypertensive women. Methods: A quasi-experimental study with a pretest–posttest design was conducted. Older hypertensive women were randomly assigned to the aerobic walking group or a control group with routine care. The intervention group received a 24-week aerobic walking program. Data were collected at baseline and 24 weeks after enrollment. Participants' characteristics, memory, subjective cognitive complaints, and plasma brain-derived neurotrophic factor were analyzed. Results: The aerobic walking group (n = 30) reported improvements in total recall, delayed recall, and subjective cognitive impairment after 24 weeks of aerobic walking. Compared to the control group (n = 28), the aerobic walking group showed significantly greater improvement in delayed recall at 24 weeks. However, aerobic walking had no significant effect on subjective cognitive complaints or brain-derived neurotrophic factor. Conclusion: The aerobic walking training significantly improved memory performance among older women with hypertension. A longer randomized controlled trial with a larger sample is necessary to confirm and further explore the effects of this intervention. [ABSTRACT FROM AUTHOR]

Background: Childbirth may pose many challenges to the psychological well-being of marriage-based immigrant mothers in interracial marriages, who must negotiate bi-dimensional acculturation – adaptation to the host culture and maintenance of her own heritage culture. We examined the temporal relationships between bi-dimensional acculturation and depressive symptoms from pregnancy to 1 year postpartum among marriage-based immigrant mothers in Taiwan using the cross-lagged structural equation modeling. Methods: This study recruited 310 immigrant mothers, who were examined in the second and third trimesters, and again at 1 month, 3 months, 6 months, and 1 year postpartum from March 2013 to December 2015. Depressive symptoms and bi-dimensional acculturation were measured using the Edinburgh Postnatal Depression Scale and Bidimensional Acculturation Scale for Marriage-Based Immigrant Women, respectively. Results: The study found that adaptation to the host culture followed a downward linear trajectory, while maintenance of the mother's own heritage culture followed an upward linear trajectory from pregnancy to 1 year postpartum. All but one cross-lagged path between bi-dimensional acculturation and depressive symptoms was statistically insignificant, though almost all cross-sectional associations were significant. Adaptation to host culture was negatively associated with depressive symptoms at all time points. The association between maintenance of heritage culture and depressive symptoms reversed from positive to negative after 6 months postpartum. Conclusions: Adaptation to the host culture and maintenance of the mother's heritage culture differed in their associations with maternal depressive symptoms. Health professionals should assist immigrant mothers in adapting to the host culture while supporting their heritage culture in the childbearing period. [ABSTRACT FROM AUTHOR]

A significant proportion of cesarean deliveries in Taiwan were without medical indications and/or on maternal request. The purpose of this study was to understand the decision-making process of choosing an elective cesarean delivery (ELCD) among primiparas in Taiwan. This qualitative exploratory study was guided by grounded theory. Data were collected through in-depth interviews with 20 primiparous women, 15 of whom chose ELCD. Verbatim transcriptions were analyzed using constant comparative analysis and methods of open, axial, and selective coding. The core category that describes the process of ELCD decision making among primiparas is 'controlling risks of childbirth and ensuring well-being.' The decision process can be divided into three phases: (1) Pre-decision: risk perception, including two subcategories, negative pre-existing ideas about normal spontaneous delivery (NSD) caused worry, and desire for ELCD as the solution; (2) In-decision: risk assessment. Women proactively collected information about NSD and cesarean delivery, and then weighed the personal risk between NSD and ELCD. Risk assessment focused on seven dimensions including safety, health, comfort, efficiency, feminine charms, time and economy; (3) Post-decision: marching onward fearlessly, including two subcategories, belief in ELCD and stress relief, and persuading stakeholders to agree and gaining the required resources for ELCD. At different phases of decision-making, women revealed different concerns, though the sequence of phases was not necessarily unidirectional. Health care providers should be aware of the decision phase and intervene at appropriate times. It is difficult to change a women's decision to have ELCD in the post-decision phase.
