Barriers and facilitators to using ophthalmic clinical health services following school vision screening: a mixed-methods study.

OBJECTIVE: To identify determinants of the utilisation of ophthalmic clinical health services among students who failed school vision screening. METHODS: This study employed a sequential explanatory mixed methods design, underpinned by Andersen's Behavioural Model of Health Service Utilisation. Data were initially gathered through interviews with 27 stakeholders-comprising 5 ophthalmologists, 7 community doctors, 7 public health professionals and 8 teachers. The qualitative insights informed the construction of a questionnaire, which subsequently garnered responses from 6215 participants. Qualitative data underwent thematic analysis with NVivo V.12, while quantitative data were analysed using multivariable multinomial logistic regression in SAS V.9.4. Data integration was performed using the Pillar Integration Process for a deductive, evidence-based synthesis of findings. RESULTS: The research revealed that students attending vision demonstration schools and receiving encouragement from schools or communities to access clinical ophthalmic services demonstrated higher adherence to referral (OR=1.66, 95% CI 1.30 to 2.12; OR=1.54, 95% CI 1.33 to 1.80). Conversely, older students and those from higher-income families exhibited lower adherence rates (OR=0.31, 95% CI 0.23 to 0.44; OR=0.34, 95% CI 0.25 to 0.46). Moreover, students with less urgent medical needs were more likely to adhere to referrals compared with those needing immediate referrals (OR=1.24, 95% CI 1.06 to 1.45).Four pillars emerged: (a) adherence decreased with age, (b) financial constraints did not pose an obstacle, (c) public health services played a critical role, (d) referral urgency did not linearly correlate with adherence. CONCLUSION: The utilisation of ophthalmic clinical health services following vision screening failure in students is significantly influenced by public health services provided by schools or communities, such as prompting those with abnormal screening results to access ophthalmic clinical health services.

Effects of school myopia management measures on myopia onset and progression among Chinese primary school students.

BACKGROUND: Schools play an organizational role in managing myopia-related behavioral habits among students. We evaluated the effects of school myopia management measures on myopia onset and progression in a school-based prospective 1-year observational study. METHODS: In total, 8319 children from 26 elementary schools were included. Online questionnaire completed by a parent, in which school myopia management experience including outdoor activities in recess or physical education class, teachers' supervision, and teaching facilities. Variables were defined as implemented well or poorly, according to the Comprehensive Plan to Prevent Myopia among Children and Teenagers. Children underwent ophthalmic examinations, and the incidence and progression of myopia from 2019 to 2020 were estimated. Multilevel logistic regression models were constructed to analyze the association between school management measures and myopia development in 8,9 years and 10,11 years students. RESULTS: From 2019 to 2020, the incidence of myopia among primary school students was 36.49%; the mean difference of spherical equivalent in myopic children was - 0.29 ± 1.22 diopters. The risk of incident myopia was reduced by 20% in 8,9 years participants with well-implemented class recess compared with those with poorly implemented class recess (adjusted odds ratio [aOR]: 0.80, p = 0.032). PE outdoor time was significantly associated with myopia incidence in 10,11 years students (aOR: 0.76, p = 0.043). Compared with poorly implemented reading and writing posture, desk and chair height, 10,11 participants with well-implemented desk and chair height were less likely to have rapid myopic progression (p = 0.029, p = 0.022). CONCLUSION: In Shanghai, children's myopia is associated with better implementation of school myopia management measures. The present findings suggest that outdoor activities during class recess or PE class, providing suitable desks and chairs, and adequate instruction in reading and writing postures might protect against pathological eye growth. An age-specific myopia prevention and control programs in school is of primary importance.

Parenting and parenting resources among Chinese parents with children under three years of age: rural and urban differences.

BACKGROUND: Parenting is essential for children's development and preventing child abuse and neglect. Providing parenting services within the primary health care settings demonstrated effectiveness in improving parenting quality. However, little is known about the status of parenting and parenting resources in rural areas and whether they differ between rural and urban areas in Mainland China. OBJECTIVE: This study aimed to examine the rural-urban differences in parenting and availability of, utilization of, and need for parenting resources among Chinese parents with children under three years of age. PARTICIPANTS AND SETTING: A total of 425 parents of children under three years of age participated in an online survey between March and May 2020. METHODS: The Parenting and Family Adjustment Scale and Child Adjustment and Parenting Efficacy Scale were used to assess parenting, family adjustment, and parenting efficacy. The availability of, utilization of, and need for parenting resources were measured using self-developed questions based on literature. Chi-square tests, t tests, and Wilcoxon rank-sum test were used to examine the differences in responses between parents in rural and urban areas. RESULTS: Compared with their urban counterparts, rural parents reported a higher level of negative parenting and more limited parenting resources. Both rural and urban parents reported low availability and utilization of parenting resources as well as a great need for parenting support services. CONCLUSIONS: Rural parents faced more parenting challenges and limited parenting resources compared with urban parents. Both rural and urban parents with children under three years of age reported great needs for parenting resources. These findings highlight the potential of delivering accessible, sustainable, and cost-effective parenting programs via the primary health care system for public welfare in both urban and rural areas, with more attention paid to rural parents to help them improve their parenting.

Association of screen time with psychological and behavioral development problems in children aged 3-6 years / 中国学校卫生

Objective@#To investigate the distribution of various types of screen time and examine the association of screen time with psychological and behavioral development problems in children aged 3-6 years, so as to provide scientific basis for children s screen use and mental health promotion.@*Methods@#A total of 3 875 mother child dyads who completed the follow up in Shanghai Maternal-Child Pairs Cohort were included. The daily usage time of children s tablet, mobile phone, TV, projectors, and other types of screens were obtained in questionnaire survey. Children s psychological and behavioral development problems were evaluated by Age-Stage Questionnaire, Third Edition (ASQ-3) and Strengths and Difficulties Questionnaire (Parent version) (SDQ). The Chi-square test, Mann Whitney U and Kruskal Wallis rank sum test were used to compare the detection rate of psychological and behavioral development problems and screen time in children with different characteristics. Multivariate binary Logistic regression was used to analyze the association of screen time with psychological and behavioral development problems.@*Results@#There were 49.91% of children having screen time more than 1 h/d. Children s TV, tablet and mobile phone screen time were 0.39(0.25, 0.96 ), 0.25(0,0.61) and 0.18(0,0.25) h/d. The detection rates of suspected developmental delay in fine motor, problem solving and personal-social domains and pro social behavior deficiency and externalizing behaviors in boys (8.54%, 6.77%, 5.46%, 30.07 %, 27.39%) were higher than that in girls (4.64%, 4.85%, 2.48%, 22.10%, 22.36%) ( χ 2=23.76, 6.49, 22.37, 31.81, 13.06, P <0.05). There were statistically significant differences in the detection rates of suspected developmental delay in communication, fine motor and problem solving, as well as internalizing behavior and externalizing behavior of children with different parents educational levels ( χ 2=14.37, 15.18, 21.10, 11.66, 9.27; 16.34, 26.75, 32.89, 16.97, 6.37, P <0.05). There were significant differences in the detection rates of suspected developmental delay in problem solving, prosocial behavior deficiency, internalizing behavior and externalizing behavior of children whose mothers had anxiety/depression symptoms during pregnancy ( χ 2= 5.61 , 9.05, 21.90, 7.17; 8.75, 6.06, 12.76 , 5.55, P <0.05). The average total screen time of boys was longer than that of girls (1.07, 1.00 h/d, Z=-2.08, P =0.04). Compared with children with other educational levels of their parents, the total screen time, mobile phone and TV screen time of children whose parents had college education or above were short (father: H =42.01, 44.49 , 21.24, mother: H =42.31, 39.21 , 26.47, P <0.01). Among all types of screen time, mobile phone screen time had the most impact on psychological and behavioral development. More mobile phone screen time increased the risk of suspected developmental delay and abnormal emotional behavior ( P < 0.05). Screen time of tablet, mobile phone and TV were positively correlated with externalizing behavior ( OR=1.36, 1.57, 1.27 , P <0.05).@*Conclusions@#Screen time is related to children s psychological and behavioral development problems and mobile phones affect the most. Parents should limit their children s screen time to avoid excessive screen time affecting their psychological and behavioral development.

The protective role of mindful parenting against child maltreatment and aggressive behavior: an exploratory study among Chinese parent-adolescent dyads.

BACKGROUND: It is well-established that child maltreatment practiced by parents is associated with adolescent aggression. Emerging evidence has suggested that higher levels of mindful parenting are associated with fewer negative parenting practices. However, the relationships among mindful parenting, child maltreatment, and adolescent aggression remain unclear. AIM: To examine the association between mindful parenting, child maltreatment, and adolescent aggressive behavior among Chinese parent-adolescent dyads. METHODS: Survey data from 554 Chinese parent-adolescent dyads were used for the analysis. Parents reported mindful parenting, and adolescents reported three forms of child maltreatment (i.e., physical abuse, psychological aggression, and neglect) by their parents and aggressive behavior. Path models were used to analyze whether higher levels of mindful parenting were associated with decreased likelihood of parent-to-adolescent maltreatment that were further related to lower levels of adolescent aggression. RESULTS: Mindful parenting and its two factors (i.e., interaction with full attention and compassion and acceptance) were associated with lower likelihood of physical abuse and psychological aggression, which were related to decreased levels of adolescent aggressive behavior. Stratified analyses by parent gender showed that the path from interaction with full attention to adolescent aggression through psychological aggression was also significant or marginally significant in both mother-adolescent and father-adolescent dyads. Stratified analyses by adolescent gender demonstrated that the paths from interaction with full attention to physical abuse and psychological aggression were significant, which were also significantly correlated with adolescent aggression among male adolescents, whereas the mindful parenting-child maltreatment-adolescent aggression paths were not significant among female adolescents. CONCLUSIONS: The findings contributed to the existing literature by assessing mindful parenting as a multifaceted construct and exploring the gender differences in the relationships. Gender-tailored interventions to improve mindful parenting, specifically focusing on the parents' ability of interacting with adolescents providing full attention, compassion, and acceptance may work towards preventing child maltreatment and promoting adolescent behavioral health.

Screen use behavior before and after COVID-19 among primary and middle school students in Shanghai / 中国学校卫生

Objective@#The current situation and associated factors of primary and middle school students screen time and related eye hygiene in different periods before and after COVID-19 were investigated, so as to provide a scientific basis for taking targeted measures of preventing and controlling myopia among those students.@*Methods@#A total of 11 402 students were selected from 24 primary schools, 18 junior high schools and 16 high schools by multi stage stratified cluster sampling method. And a questionnaire survey was conducted among students and their parents to understand students screen time and screen hygiene behaviors and related factors in different periods before and after the outbreak of COVID-19.@*Results@#The rate of screen overuse was 7.26%, 9.12% and 35.30% during school days, weekends and home study, respectively. The overuse rate of mobile phones and tablets at home increases with the increase of school stage. Totally 16.30% of students use mobile phones for online learning. The screen overuse rate of those who have not been diagnosed with myopia was lower than that of those who have been diagnosed during home study( OR=0.77, P <0.05). The higher the parents educational level was, the lower the screen overuse rate of children during the weekends became( P <0.05). In any period, the high proportion of screens used in homework and poor home screen eye environment increased the risk of screen overuse and poor eye hygiene ( P <0.05). Parental good behavior was conducive to reducing the risk( OR= 0.65-0.97, P <0.05). When the family had regulation on the screen use time, the implementation of laxity would increase the risk of screen overuse ( OR=1.18-2.48, P <0.05).@*Conclusion@#The screen overuse rate of urban primary and middle school students during home study is high, and a certain proportion of students still use mobile phones for online learning. The proportion of screens used in homework, home screen eye environment and screen use management are related to screens overuse. More attention should be paid to those with myopia and low educational level of parents.

Objective@#To determine the influencing factors of electronic screen time of urban preschoolers before and after the COVID-19 outbreak, so as to provide a scientific basis for the control of digital screen use and early prevention of myopia among preschoolers.@*Methods@#Using multi stage cluster random sampling method, a cross sectional survey of 8 244 kindergarten students in a district of Shanghai was implemented, through parent questionnaire collecting the time child spent on various electronic screens before and after the COVID-19 outbreak, estimated the weighting screen time, and emphatically analyzed the relationship between family electronic screen supervision behavior and preschoolers weighting screen time.@*Results@#The proportion of daily over use time on average of mobile phones, computers and TV/projection screens among the surveyed preschool children during COVID-19 was 30.52%, 51.40% and 56.82%, respectively. On school days before the epidemic, the proportion was 21.94%, 41.80% and 47.51% respectively. After controlling for primary covariates, parents frequent control of children s electronic screen use, parents guidance for electronic screen use were significantly associated with lower weighted screen refractive time ( OR =0.60-0.77, P < 0.05 ). The use of electronic screen when parents accompanied their children, the use of electronic screen time by parents but not strictly implemented were significantly associated with higher weighted screen refractive time and increased screen refractive time ( OR =1.18-1.80, P <0.05).@*Conclusion@#Urban preschoolers electronic screen time was high during and before COVID-19. In the control measures of preschool children s electronic screen time, attention should be paid to the management of electronic screen use within the family and parents role model.

[Correlation of fetuin-B concentrations in serum and follicular fluid with outcomes of in vitro fertilization].

OBJECTIVE: To investigate the relationship between serum/follicular fluid fetuin B levels and outcome of in vitro fertilization (IVF). METHODS: Infertility women (28 with low fertilization rates, 44 with normal fertilization rates) receiving IVF in Women's Hospital of Zhejiang University School of Medicine during June and December 2016 were enrolled in the study. Serum/follicular fluid fetuin B levels were measured with ELISA method. Correlations of serum and follicular fetuin B level with fertilization outcome of IVF were analyzed with Pearson correlation coefficient and receiver operating characteristic (ROC) curve. RESULTS: A positive correlation between serum fetuin B and follicular fluid fetuin B levels was observed (r=0.675, P<0.01). Both serum and follicular fluid fetuin B levels in women with low fertilization rates of IVF were lower than those in women with normal fertilization rates[(6.09±1.31) µg/mL vs. (7.13±1.47) µg/mL, t=3.050, P<0.05; (5.13±0.96)µg/mL vs. (6.22±1.33) µg/mL, t=3.755, P<0.01]. ROC analysis showed that the area under curve (AUC) of serum fetuin B level in predicting fertilization rate was 0.832 (95% CI:0.729-0.934, P<0.01), and 6.08 µg/mL could be used as cut-off value. CONCLUSIONS: Serum fetuin B level is correlated with follicular fluid fetuin B level, and it may be used for predicting the fertilization outcome of IVF.
