Objective: This study aimed to explore the experiences of women in the process of formula feeding their infants. The World Health Organization has emphasized the importance of breastfeeding for infant health. After decades of breastfeeding promotions,breastfeeding rates in Hong Kong have been rising consistently; however, the low continuation rate is alarming. This study explores women's experiences with formula feeding their infants, including factors affecting their decision to do so.Methods: A qualitative approach using an interpretative phenomenological analysis(IPA) was adopted as the study design. Data were collected from 2014 to 2015 through individual in-depth unstructured interviews with 16 women, conducted between 3 and 12 months after the birth of their infant. Data were analyzed using IPA.Results: Three main themes emerged as follows:(1) self-struggle, with the subthemes of feeling like a milk cow and feeling trapped;(2) family conflict, with the subtheme of sharing the spotlight; and(3) interpersonal tensions, with the subthemes of embarrassment,staring, and innocence. Many mothers suffered various stressors and frustrations during breastfeeding. These findings suggest a number of pertinent areas that need to be considered in preparing an infant feeding campaign.Conclusions: The findings of this study reinforce our knowledge of women's struggles with multiple sources of pressure, such as career demands, childcare demands, and family life after giving birth. All mothers should be given assistance in making informed decisions about the optimal approach to feeding their babies given their individual situation and be provided with support to pursue their chosen feeding method. 展开更多

Reoccurring symptoms and persistent problems that continue post treatment can be characteristic of the vaginal infections Bacterial Vaginosis (BV) and recurrent vulvovaginal candidiasis (RVVC). The purpose of this study was to describe women’s life experiences in managing the symptoms of bacterial vaginosis and Candida. Sixteen women were recruited and participated in an interview study when they contacted a Swedish gynecology clinic with vaginal complaints that ranged from and included abnormal discharge, irritation itching along with serious malodor. An interpretive phenomenological approach was used with an individual interview to get a more intimate understanding of the women experiencing these problems. The finding of this study shows that managing the recurrent symptoms of the infections remains to be a challenge for women as it has a clearly negative impact on the quality of their lives. Four themes developed: frustration and mood disorders, intimacy changes in the relationship, exposure, hope and relief. The women had high hopes of eliminating the symptoms within the six-month study period. The treatment program, with its well-developed guidelines and continuity of care within the context of the study greatly improved the quality of life of these women. Women had feelings of frustration and anxiety when nothing could cure their problem while they had also a great hope to get rid of the symptoms with a long striking treatment. Well-developed guidelines and continuity of care can help these women to have an improved quality of life. 展开更多

Despite the growing recognition of women’s increasing role in the household and corresponding empowerment programs in sub-Saharan Africa,intensive research on the relationship between women’s influence and household food consumption is minimal.Using the most recent(2017-2018)national household survey data from Tanzania,this study examined the influence of women’s empowerment on household food consumption.First,we compared the monthly consumption of eight food categories between female-headed households(FHHs)and male-headed households(MHHs)using both descriptive statistics and the propensity score matching(PSM)method.Furthermore,we adopted the two-stage Linear Expenditure System and Almost Ideal Demand System model(LES-AIDS)to estimate income and price elasticities for the two household types.The results show that FHHs consume bread and cereals,fish,oils and fats,vegetables,and confectionery(sugar,jam,honey,chocolate,etc.)more than MHHs.Moreover,FHHs have a significantly higher income elasticity of demand for all food groups than MHHs.They are also more price elastic than MHHs in meat,fish,oils,fats,sugar,jam,honey,chocolate,etc. 展开更多

The participation of women in legislation is an important aspect and means of safeguarding women’s rights.Feminist theory,based on criticism of both the“citizenship identity theory as rights”and the“citizenship identity theory as responsibilities,”proposes the“citizenship identity theory as subjectivity.”Observing the current practice of women’s participation in legislation in China,two institutional safeguard principles can be summarized:the“minimum proportion”and the“influence evaluation.”However,each of these principles has its inherent limitations.Therefore,it is necessary to supplement them with the principle of“subjective participation”in a reflective manner.This principle requires women to participate substantively in the legislative process as subjects,express women’s needs and demands,input women’s perspectives and experiences,and reconstruct the distribution of rights and responsibilities in the existing legislation.The three principles complement each other and work together to comprehensively constitute the institutional structure of women’s participation in legislation,thereby promoting the reproduction of corresponding action structures. 展开更多

When studying the phenomenon of the induced electromotive force, which originates from Faraday’s unipolar inductor, the contrast between Faraday’s view of the magnetic field dynamic lines and the theory of relativity is revealed. In order to remove this contradiction, this phenomenon was studied in depth, theoretically and experimentally, using an experimental setup similar to Faraday’s. Calculations of the induced electromotive force, based on relativity on the one hand and on Faraday’s view on the other were made with the help of measurements of the magnetic field components. Accurate magnetic field measurements are confirmed by analytical calculations. Precise-induced electromotive force measurements confirmed Faraday’s view and contradicted the theory of relativity. 展开更多

The development of women’s higher education in China can be divided into four stages:emergence(1908-1948);foundation(1949-1976);accelerating development(1977-2008);and the qualitative leap(2009-2020).This work considers the principal institutional mechanisms that contributed to this development.First,flexibly planned parenthood gradually promoted gender equality and openness in society facilitated by systematic“awards,grants,and loans”initiatives to support women’s higher education economically.Second,compulsory education ensured that left-out and migrant children had access to higher education.Third,effective connectivity across different education types bridged education gaps between those with different levels of education.Fourth,China made great efforts to invite and integrate international experiences that promoted the development of women’s higher education.Looking beyond these achievements,we also discuss the future trends of women’s higher education in China. 展开更多

Objectives: The aim of this study was to evaluate how Swedish women describe their emotional state of being during the eighth week through the eleventh week after they have become pregnant again after suffering a previous miscarriage. Method: A qualitative content analysis with an inductive approach has been used to analyze fourteen interviews that served as the data base for this study. The content analysis resulted in the development of five categories which evolved into one primary theme. Findings: The five categories identified were Worry and preoccupation;Distance;managing their feelings;Mourning what is lost;Guarded happiness and expectations. These categories were compiled into a main theme, “Worry consumes a lot of energy, but on the other side lies happiness”. This theme focused on whether the women could feel any happiness about being pregnant again despite their concerns with the previous miscarriage. Conclusions: The emotional states of the women when they get pregnant again are typically characterized by anxiety, worry and concerns about their current pregnancy. The women have a tendency to distance themselves emotionally from their pregnancy but also strive to find the joy of being pregnant again. During the new pregnancy they find themselves in need of support from their family and friends as well as in need of support from the healthcare system. 展开更多

Pregnancy could be associated with an increased risk of GBV. Objective: To determine the experience of, and perception on GBV by pregnant Nigerian women. Methodology: A questionnaire-based cross-sectional study involving 250 pregnant women from six selected health facilities in Anambra, Southeastern Nigeria was conducted to elicit their experience of, and perceptions on gender based violence. Data analysis employed statistical package for social sciences (SPSS) version 22.0. Statistical comparison of variables employed Chi-square test, with significance levels comprising of p Results: Only 80 (32.0%) of the respondents were aware of GBV while 17 (6.8%) and 20 (8.0%) had experienced it in the index and previous pregnancies respectively. Physical violence was the most commonly experienced 18 (58.1%), while marital quarrel and drunkenness were the most commonly perceived causes, 21 (26.3%) apiece. Up to 33.7% of the respondents would report GBV to the law enforcement agencies;22.5% would seek medical attention and only 2.5% would do nothing. The most common source of information on GBV was public lecture (32.5%) followed by media (26.3%). As high as 49 (61.3%) of the respondents that are aware of GBV (N = 80), thought that GBV could be prevented while up to 53 (66.3%) were aware of the strategies for its prevention. Conclusion: Awareness of GBV in this study is low (32.0%) while experience is even lower at 6.8%, and 8.0% for the index and previous pregnancies respectively. Information on prevention strategies for GBV is also low. The need to develop comprehensive reproductive health (RH) policy that incorporates GBV and its management, to be taught in educational institutions is highlighted. The importance of public health lectures and the employment of various media platforms as reproductive right enlightenment modalities, towards creating awareness on the prevention and combat of GBV are also highlighted. 展开更多

In many instances, care for the elderly, especially in long-term care institutions, is provided under minimal supervision by caregivers who are lay people. This can lead to poor quality care or neglect of the elderly. The research question was: “How competent are lay caregivers for the elderly in old age homes, who often lack the opportunity for training to improve their knowledge and skills, in delivering care to the elderly? The aims of the study were to explore and describe the experiences of both the caregivers and the elderly in respect of caring for the elderly in old age homes. The objectives of the study were to explore and describe the experiences of the caregivers and the elderly with respect to caring for the elderly and in respect of nursing care they received. A qualitative, explorative, descriptive, contextual and phenomenology design was used to perform this study. In the situational analysis, the experiences and needs of the caregivers were described. Themes in terms of interpersonal relationships that could be positive or negative regarding the elderly were identified. These included lack of regular in-service training sessions for caregivers. Likewise, sub-themes like communication, support and caring for elderly people were revealed. Inadequate knowledge of caregivers in caring procedures, a shortage of staff, equipment and absence of policies which should support and guide the work of caregivers impacts negatively on the care of the elderly. From the experiences of the elderly and caregivers, the competencies under scrutiny emerged and were measured qualitatively by the perceptions of the elderly, in respect of the caring they were exposed to. 展开更多

Aims/Background: Perceived experiences of childbirth are important for mothers as they affect their self-esteem, mother-child interactions, subsequent mother-child bonding, and their desire for another child. This study examined the factor structure and construct validity of Salmon and Drew’s Multidimensional Assessment of Women’s Experience of Childbirth (MAWEC) in Japanese. Design/Methods: This study conducted a questionnaire survey using the Japanese version of the MAWEC and other variables with 759 women with infants in Japan. The participants’ mean (standard deviation [SD], range) age was 31.9 (5.3, 18 - 46) years. A total of 353 (46.5%) participants were primiparous and 384 (50.6%) were multiparous, and 22 (2.9%) did not answer. The data were randomly divided into two groups for exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) and separately analyzed the positive- and negative-worded items. I conducted EFA using the maximum-likelihood method with PROMAX rotation from one-through two- and three-factor structures. Different factor structure models were compared in terms of CFAs using, as indicator of goodness-of-fit, chi-square/df, comparative fit index (CFI), and root mean square of error approximation (RMSEA). Results: This study showed that a bifactor model for the MAWEC with four subscales (positive emotion, positive coping, negative emotion, and negative coping) fit the data the best. These four subscales were associated with demographic, obstetric, neonatal, and feeding characteristics. For example, primiparas were more vulnerable to coping aspects of perceived childbirth experiences, including sense of mastery over the delivery process and ability to enjoy the delivery. Gestational age at birth was associated with emotional aspects of perceived childbirth experiences. Conclusion: The Japanese version of the MAWEC consists of four aspects regarding perceived childbirth experience. Perinatal health professionals may examine women’s childbirth experiences from these four perspectives. . 展开更多

Background: More than half a million women and four million infants are reported to die every year due to complications related to pregnancy and child bearing. The efforts to improve quality maternity care have been on the World Health Organization member countries’ agenda. Zambia has been striving to reduce maternal mortality by ensuring universal access to maternal and child health care services. Our study aimed to explore women’s experience with socio-economic factors associated with perinatal morbidity and mortality in Lusaka and Mumbwa districts, Zambia. Methodology: This hermeneutic phenomenological study was conducted at four health facilities in Mumbwa and Lusaka Districts of Zambia. A purposeful sample of 45 consenting women organized in four groups was selected. Each group comprised of 11 to 12 women. The focus group discussion guide was used to direct the discussion and the Olympus Digital Voice Recorder WS-852 (Olympus Corporation, Shinjuku, Tokyo, Japan) was used to record the discussions. The audio data was manually transcribed and verbatim transcript analyzed using ATLAS.ti 8.0 qualitative data software (ATLAS.ti Scientific Software Development GmbH, Berlin, Germany) to ascertain patterns of relationships between themes and quotations. Results: Money, husbands and family support, adequate health care resources, and good nurses attitude simplify the burden of pregnancy, delivery and child rearing for the health care providers, mothers and society. Conclusion: Having money and all the necessary resources during pregnancy simplifies the burden of pregnancy, delivery and child rearing for the health care providers, mothers and society. Women are still ignorant and believe in myths and need information on the dangers of depending on herbs and God in preparation for labor and care of the new born, but also seek help from qualified medical personnel when labor starts. Nurse’s attitude needs to change to ensure a reduction in women and newborn mortalities. Nurses were mentioned as the cause of mortality among women and newborn. Recommendations: There’s a need for training of nurses and other health care workers on self-awareness of attitudes. Women should be empowered with resources that facilitate labor and delivery. Midwives and health care providers should take responsibility for evaluating and correcting the beliefs and traditional practices of the community. Training should be planned for raising awareness in order to support beneficial practices and prevent harmful ones. 展开更多

Pension funds remain scarce no matter what institutional design is adopted. China has a host of unique issues facing its pension system,issues that must be confronted; for instance,the disappearance of its demographic dividends and legacy costs incurred due to institutional transition. Such features determine that China’s pension system is merely passable at the present time. In this article,Professor Cai Fang offers new and incisive perspectives on this issue,such as the potential stimulus for economic growth by ageing people’s desire to save money for old-age provisions. 展开更多

AIM: To prospectively assess the impact of time of endoscopy and endoscopist's experience on the outcome of non-variceal acute upper gastrointestinal (GI) bleeding patients in a large teaching hospital.METHODS: All patients admitted for non-variceal acute upper GI bleeding for over a 2-year period were potentially eligible for this study. They were managed by a team of seven endoscopists on 24-h call whose experience was categorized into two levels (high and low) according to the number of endoscopic hemostatic procedures undertaken before the study. Endoscopic treatment was standardized according to Forrest classification of lesions as well as the subsequent medical therapy. Time of endoscopy was subdivided into two time periods: routine (8 a.m.-5 p.m.) and on-call (5 p.m.-8 a.m.). For each category of experience and time periods rebleeding rate, transfusion requirement, need for surgery, length of hospital stay and mortality we compared. Multivariate analysis was used to discriminate the impact of different variables on the outcomes that were considered.RESULTS: Study population consisted of 272 patients (mean age 67.3 years) with endoscopic stigmata of hemorrhage. The patients were equally distributed among the endoscopists, whereas only 19% of procedures were done out of working hours. Rockall score and Forrest classification at admission did not differ between time periods and degree of experience.Univariate analysis showed that higher endoscopist's experience was associated with significant reduction in rebleeding rate (14% vs 37%), transfusion requirements (1.8±0.6 vs 3.0±1.7 units) as well as surgery (4% vs 10%), but not associated with the length of hospital stay nor mortality. By contrast, outcomes did not significantly differ between the two time periods of endoscopy.On multivariate analysis, endoscopist's experience was independently associated with rebleeding rate and transfusion requirements. Odds ratios for low experienced endoscopist were 4.47 for rebleeding and 6.90 for need of transfusion after the endoscopy.CONCLUSION: Endoscopist's experience is an important independent prognostic factor for non-variceal acute upper GI bleeding. Urgent endoscopy should be undertaken preferentially by a skilled endoscopist as less expert staff tends to underestimate some risk lesions with a negative influence on hemostasis. 展开更多
