ItemThe Cumulative Effect of Multilevel Factors on Myopia Prevalence, Incidence, and Progression Among Children and Adolescents in China During the COVID-19 PandemicDong, Y ; Jan, C ; Chen, L ; Ma, T ; Liu, J ; Zhang, Y ; Ma, Q ; Zhong, P ; Song, Y ; Ma, J ; Patton, GC ; Sawyer, SM (ASSOC RESEARCH VISION OPHTHALMOLOGY INC, 2022-12)PURPOSE: To estimate the effects of school closures and associated lifestyle changes on myopia in Chinese children and adolescents during the coronavirus disease 2019 (COVID-19) pandemic. METHODS: Two cross-sectional surveys recruited 14,296 Chinese students aged 7 to 18 years in November 2019 and June 2020 from which an open cohort study (nested queue design) was derived and used to assess myopia prevalence, incidence, and progression rates (defined as students with progression in myopia severity at the second survey wave among those with myopia at baseline). The severity of myopia was determined by measurements of visual acuity (<5.0) and noncycloplegic refraction (spherical equivalent <-0.50 diopters). Twenty-three myopia-influencing factors were divided into three categories: eye-use habits, lifestyle, and family and subjective factors. Responses to each of these 23 factors were labeled as either positive or negative options and then combined to generate a comprehensive score. RESULTS: Boys and girls were equally represented (50%) and had the same average age (11.5 years) at each wave. The myopia prevalence increased from 48.2% to 60.0%, with 27.1% myopia incidence and 13.2% myopia progression rates for Chinese children and adolescents. Each of the 23 factors was associated with myopia prevalence but had no significant effect on myopia incidence or progression. However, these 23 factors had a cumulative effect on myopia risks; higher scores were associated with more positive factors and lower risk ratios of myopia and vice versa. Except for the progression rate, the myopia prevalence and incidence and risk ratios decreased with higher comprehensive scores. CONCLUSIONS: School closures during the COVID-19 pandemic increased the risk of myopia in Chinese children and adolescents due to the accumulation of poor eyesight habits, unhealthy lifestyles, and excessive screen time. TRANSLATIONAL RELEVANCE: Rather than focusing on single risk factors for myopia, future myopia prevention strategies should focus on integrating multiple comprehensive approaches across schools, families, and communities.

ItemMapping age- and sex-specific HIV prevalence in adults in sub-Saharan Africa, 2000-2018.Haeuser, E ; Serfes, AL ; Cork, MA ; Yang, M ; Abbastabar, H ; Abhilash, ES ; Adabi, M ; Adebayo, OM ; Adekanmbi, V ; Adeyinka, DA ; Afzal, S ; Ahinkorah, BO ; Ahmadi, K ; Ahmed, MB ; Akalu, Y ; Akinyemi, RO ; Akunna, CJ ; Alahdab, F ; Alanezi, FM ; Alanzi, TM ; Alene, KA ; Alhassan, RK ; Alipour, V ; Almasi-Hashiani, A ; Alvis-Guzman, N ; Ameyaw, EK ; Amini, S ; Amugsi, DA ; Ancuceanu, R ; Anvari, D ; Appiah, SCY ; Arabloo, J ; Aremu, O ; Asemahagn, MA ; Jafarabadi, MA ; Awedew, AF ; Quintanilla, BPA ; Ayanore, MA ; Aynalem, YA ; Azari, S ; Azene, ZN ; Darshan, BB ; Babalola, TK ; Baig, AA ; Banach, M ; Bärnighausen, TW ; Bell, AW ; Bhagavathula, AS ; Bhardwaj, N ; Bhardwaj, P ; Bhattacharyya, K ; Bijani, A ; Bitew, ZW ; Bohlouli, S ; Bolarinwa, OA ; Boloor, A ; Bozicevic, I ; Butt, ZA ; Cárdenas, R ; Carvalho, F ; Charan, J ; Chattu, VK ; Chowdhury, MAK ; Chu, D-T ; Cowden, RG ; Dahlawi, SMA ; Damiani, G ; Darteh, EKM ; Darwesh, AM ; das Neves, J ; Weaver, ND ; De Leo, D ; De Neve, J-W ; Deribe, K ; Deuba, K ; Dharmaratne, S ; Dianatinasab, M ; Diaz, D ; Didarloo, A ; Djalalinia, S ; Dorostkar, F ; Dubljanin, E ; Duko, B ; El Tantawi, M ; El-Jaafary, SI ; Eshrati, B ; Eskandarieh, S ; Eyawo, O ; Ezeonwumelu, IJ ; Ezzikouri, S ; Farzadfar, F ; Fattahi, N ; Fauk, NK ; Fernandes, E ; Filip, I ; Fischer, F ; Foigt, NA ; Foroutan, M ; Fukumoto, T ; Gad, MM ; Gaidhane, AM ; Gebregiorgis, BG ; Gebremedhin, KB ; Getacher, L ; Ghadiri, K ; Ghashghaee, A ; Golechha, M ; Gubari, MIM ; Gugnani, HC ; Guimarães, RA ; Haider, MR ; Haj-Mirzaian, A ; Hamidi, S ; Hashi, A ; Hassanipour, S ; Hassankhani, H ; Hayat, K ; Herteliu, C ; Ho, HC ; Holla, R ; Hosseini, M ; Hosseinzadeh, M ; Hwang, B-F ; Ibitoye, SE ; Ilesanmi, OS ; Ilic, IM ; Ilic, MD ; Islam, RM ; Iwu, CCD ; Jakovljevic, M ; Jha, RP ; Ji, JS ; Johnson, KB ; Joseph, N ; Joshua, V ; Joukar, F ; Jozwiak, JJ ; Kalankesh, LR ; Kalhor, R ; Kamyari, N ; Kanchan, T ; Matin, BK ; Karimi, SE ; Kayode, GA ; Karyani, AK ; Keramati, M ; Khan, EA ; Khan, G ; Khan, MN ; Khatab, K ; Khubchandani, J ; Kim, YJ ; Kisa, A ; Kisa, S ; Kopec, JA ; Kosen, S ; Laxminarayana, SLK ; Koyanagi, A ; Krishan, K ; Defo, BK ; Kugbey, N ; Kulkarni, V ; Kumar, M ; Kumar, N ; Kusuma, D ; La Vecchia, C ; Lal, DK ; Landires, I ; Larson, HJ ; Lasrado, S ; Lee, PH ; Li, S ; Liu, X ; Maleki, A ; Malik, P ; Mansournia, MA ; Martins-Melo, FR ; Mendoza, W ; Menezes, RG ; Mengesha, EW ; Meretoja, TJ ; Mestrovic, T ; Mirica, A ; Moazen, B ; Mohamad, O ; Mohammad, Y ; Mohammadian-Hafshejani, A ; Mohammadpourhodki, R ; Mohammed, S ; Mohammed, S ; Mokdad, AH ; Moradi, M ; Moraga, P ; Mubarik, S ; Mulu, GBB ; Mwanri, L ; Nagarajan, AJ ; Naimzada, MD ; Naveed, M ; Nazari, J ; Ndejjo, R ; Negoi, I ; Ngalesoni, FN ; Nguefack-Tsague, G ; Ngunjiri, JW ; Nguyen, CT ; Nguyen, HLT ; Nnaji, CA ; Noubiap, JJ ; Nuñez-Samudio, V ; Nwatah, VE ; Oancea, B ; Odukoya, OO ; Olagunju, AT ; Olakunde, BO ; Olusanya, BO ; Olusanya, JO ; Bali, AO ; Onwujekwe, OE ; Orisakwe, OE ; Otstavnov, N ; Otstavnov, SS ; Owolabi, MO ; Mahesh, PA ; Padubidri, JR ; Pana, A ; Pandey, A ; Pandi-Perumal, SR ; Kan, FP ; Patton, GC ; Pawar, S ; Peprah, EK ; Postma, MJ ; Preotescu, L ; Syed, ZQ ; Rabiee, N ; Radfar, A ; Rafiei, A ; Rahim, F ; Rahimi-Movaghar, V ; Rahmani, AM ; Ramezanzadeh, K ; Rana, J ; Ranabhat, CL ; Rao, SJ ; Rawaf, DL ; Rawaf, S ; Rawassizadeh, R ; Regassa, LD ; Rezaei, N ; Rezapour, A ; Riaz, MA ; Ribeiro, AI ; Ross, JM ; Rubagotti, E ; Rumisha, SF ; Rwegerera, GM ; Moghaddam, SS ; Sagar, R ; Sahiledengle, B ; Sahu, M ; Salem, MR ; Kafil, HS ; Samy, AM ; Sartorius, B ; Sathian, B ; Seidu, A-A ; Shaheen, AA ; Shaikh, MA ; Shamsizadeh, M ; Shiferaw, WS ; Shin, JI ; Shrestha, R ; Singh, JA ; Skryabin, VY ; Skryabina, AA ; Soltani, S ; Sufiyan, MB ; Tabuchi, T ; Tadesse, EG ; Taveira, N ; Tesfay, FH ; Thapar, R ; Tovani-Palone, MR ; Tsegaye, GW ; Umeokonkwo, CD ; Unnikrishnan, B ; Villafañe, JH ; Violante, FS ; Vo, B ; Vu, GT ; Wado, YD ; Waheed, Y ; Wamai, RG ; Wang, Y ; Ward, P ; Wickramasinghe, ND ; Wilson, K ; Yaya, S ; Yip, P ; Yonemoto, N ; Yu, C ; Zastrozhin, MS ; Zhang, Y ; Zhang, Z-J ; Hay, SI ; Dwyer-Lindgren, L ; Local Burden of Disease sub-Saharan Africa HIV Prevalence Collaborators, (Springer Science and Business Media LLC, 2022-12-19)BACKGROUND: Human immunodeficiency virus and acquired immune deficiency syndrome (HIV/AIDS) is still among the leading causes of disease burden and mortality in sub-Saharan Africa (SSA), and the world is not on track to meet targets set for ending the epidemic by the Joint United Nations Programme on HIV/AIDS (UNAIDS) and the United Nations Sustainable Development Goals (SDGs). Precise HIV burden information is critical for effective geographic and epidemiological targeting of prevention and treatment interventions. Age- and sex-specific HIV prevalence estimates are widely available at the national level, and region-wide local estimates were recently published for adults overall. We add further dimensionality to previous analyses by estimating HIV prevalence at local scales, stratified into sex-specific 5-year age groups for adults ages 15-59 years across SSA. METHODS: We analyzed data from 91 seroprevalence surveys and sentinel surveillance among antenatal care clinic (ANC) attendees using model-based geostatistical methods to produce estimates of HIV prevalence across 43 countries in SSA, from years 2000 to 2018, at a 5 × 5-km resolution and presented among second administrative level (typically districts or counties) units. RESULTS: We found substantial variation in HIV prevalence across localities, ages, and sexes that have been masked in earlier analyses. Within-country variation in prevalence in 2018 was a median 3.5 times greater across ages and sexes, compared to for all adults combined. We note large within-district prevalence differences between age groups: for men, 50% of districts displayed at least a 14-fold difference between age groups with the highest and lowest prevalence, and at least a 9-fold difference for women. Prevalence trends also varied over time; between 2000 and 2018, 70% of all districts saw a reduction in prevalence greater than five percentage points in at least one sex and age group. Meanwhile, over 30% of all districts saw at least a five percentage point prevalence increase in one or more sex and age group. CONCLUSIONS: As the HIV epidemic persists and evolves in SSA, geographic and demographic shifts in prevention and treatment efforts are necessary. These estimates offer epidemiologically informative detail to better guide more targeted interventions, vital for combating HIV in SSA.

ItemNo Preview AvailableParental history of positive development and child behavior in next generation offspring: A two-cohort prospective intergenerational studyLetcher, P ; Greenwood, CJ ; McAnally, H ; Belsky, J ; Macdonald, JA ; Spry, EA ; Thomson, KC ; O'Connor, M ; Sligo, J ; Youssef, G ; McIntosh, JE ; Iosua, E ; Hutchinson, D ; Cleary, J ; Sanson, A ; Patton, GC ; Hancox, RJ ; Olsson, CA (WILEY, 2023-01)This study examined whether positive development (PD) in adolescence and young adulthood predicts offspring behavior in two Australasian intergenerational cohorts. The Australian Temperament Project Generation 3 Study assessed PD at age 19-28 (years 2002-2010) and behavior in 1165 infants (12-18 months; 608 girls) of 694 Australian-born parents (age 29-35; 2012-2019; 399 mothers). The Dunedin Multidisciplinary Health and Development Parenting Study assessed PD at age 15-18 (years 1987-1991) and behavior in 695 preschoolers (3-5 years; 349 girls) and their New Zealand born parents (age 21-46; 1994-2018; 363 mothers; 89% European ethnicity). In both cohorts, PD before parenthood predicted more positive offspring behavior (βrange = .11-.16) and fewer behavior problems (βrange = -.09 to -.11). Promoting strengths may secure a healthy start to life.

ItemNo Preview AvailableLearning outcomes in primary school children with emotional problems: a prospective cohort studyMundy, LK ; Canterford, L ; Moreno-Betancur, M ; Hoq, M ; Viner, RM ; Bayer, JK ; Lietz, P ; Redmond, G ; Patton, GC (WILEY, 2023-09)BACKGROUND: Academic difficulties are common in adolescents with mental health problems. Although earlier childhood emotional problems, characterised by heightened anxiety and depressive symptoms are common forerunners to adolescent mental health problems, the degree to which mental health problems in childhood may contribute independently to academic difficulties has been little explored. METHODS: Data were drawn from a prospective cohort study of students in Melbourne, Australia (N = 1239). Data were linked with a standardised national assessment of academic performance at baseline (9 years) and wave three (11 years). Depressive and anxiety symptoms were assessed at baseline and wave two (10 years). Regression analyses estimated the association between emotional problems (9 and/or 10 years) and academic performance at 11 years, adjusting for baseline academic performance, sex, age and socioeconomic status, and hyperactivity/inattention symptoms. RESULTS: Students with depressive symptoms at 9 years of age had lost nearly 4 months of numeracy learning two years later after controlling for baseline academic performance and confounders. Results were similar for anxiety symptoms. Regardless of when depressive symptoms occurred there were consistent associations with poorer numeracy performance at 11 years. The association of depressive symptoms with reading performance was weaker than for numeracy if they were present at wave two. Persistent anxiety symptoms across two waves led to nearly a 4 month loss of numeracy learning at 11 years, but the difference was not meaningful for reading. Findings were similar when including hyperactivity/inattention symptoms. CONCLUSIONS: Childhood anxiety and depression are not only forerunners of later mental health problems but predict academic achievement. Partnerships between education and health systems have the potential to not only improve childhood emotional problems but also improve learning.

ItemNo Preview AvailableEstradiol variability is associated with brain structure in early adolescent femalesZwaan, IS ; Felmingham, K ; Vijayakumar, N ; Patton, G ; Mundy, L ; Byrne, ML ; Simmons, J ; Whittle, S (PERGAMON-ELSEVIER SCIENCE LTD, 2022-12)One-third of adolescents are diagnosed with a psychiatric disorder by age 16, with female adolescents twice as likely to experience an internalizing (i.e., depression or anxiety) disorder as their male peers. Individual differences in pubertal factors may partially underlie this disparity, potentially via the role of pubertal hormones in shaping brain development. While research has examined links between estradiol levels and brain structure, individual variation in estradiol levels has not been considered. Using longitudinal data from 44 female adolescents (baseline age M = 11.7; follow-up age M= 13.3), we examined associations between both average estradiol and estradiol variability, and brain gray matter structure at baseline. We used a hypothesis-driven region of interest (ROI) approach focusing on subcortical and ventromedial prefrontal regions, in addition to an exploratory whole-brain analysis. We also investigated whether brain structure mediated the association between estradiol measures and internalizing (i.e., anxious and depressive) symptoms at follow-up. ROI analyses revealed a significant negative association between estradiol variability and thickness of the right medial orbitofrontal cortex (OFC, β = -0.39, FDR corrected p = .010). There were, however, no significant associations between average estradiol or estradiol variability and internalizing symptoms, nor was there evidence of mediation. Our results indicate that increased variation in estradiol levels across a month is associated with decreased cortical thickness in a brain region implicated in emotion processing, although implications for mental health are unclear. Findings, however, highlight the importance of considering individual variation in estradiol when examining links to brain development.

ItemNo Preview AvailableBetter together: Advancing life course research through multi-cohort analytic approachesO'Connor, M ; Spry, E ; Patton, G ; Moreno-Betancur, M ; Arnup, S ; Downes, M ; Goldfeld, S ; Burgner, D ; Olsson, CA (ELSEVIER SCI LTD, 2022-09)Longitudinal cohorts can provide timely and cost-efficient evidence about the best points of health service and preventive interventions over the life course. Working systematically across cohorts has the potential to further exploit these valuable data assets, such as by improving the precision of estimates, enhancing (or appropriately reducing) confidence in the replicability of findings, and investigating interrelated questions within a broader theoretical model. In this conceptual review, we explore the opportunities and challenges presented by multi-cohort approaches in life course research. Specifically, we: 1) describe key motivations for multi-cohort work and the analytic approaches that are commonly used in each case; 2) flag some of the scientific and pragmatic challenges that arise when adopting these approaches; and 3) outline emerging directions for multi-cohort work in life course research. Harnessing their potential while thoughtfully considering limitations of multi-cohort approaches can contribute to the robust and granular evidence base needed to promote health and wellbeing over the life span.

ItemNo Preview AvailableFrom adolescence to parenthood: a multi-decade study of preconception mental health problems and postpartum parent-infant bondsMacdonald, JA ; Greenwood, C ; Letcher, P ; Spry, EA ; McAnally, HM ; Thomson, K ; Hutchinson, D ; Youssef, GJ ; McIntosh, J ; Hancox, RJ ; Patton, GC ; Olsson, CA (SPRINGER HEIDELBERG, 2022-03)PURPOSE: To examine associations between anxiety and depressive symptoms across adolescence and young adulthood with subsequent maternal- and paternal-infant bonding at 1 year postpartum. METHODS: The data were from a prospective, intergenerational cohort study. Participants (381 mothers of 648 infants; 277 fathers of 421 infants) self-reported depression and anxiety at three adolescent waves (ages 13, 15 and 17 years) and three young adult waves (ages 19, 23 and 27 years). Subsequent parent-infant bonds with infants were reported at 1 year postpartum (parent age 29-35 years). Generalised estimating equations (GEE) separately assessed associations for mothers and fathers. RESULTS: Mean postpartum bonding scores were approximately half a standard deviation lower in parents with a history of persistent adolescent and young adult depressive symptoms (maternal βadj = - 0.45, 95% CI - 0.69, - 0.21; paternal βadj = - 0.55, 95% CI - 0.90, 0.20) or anxiety (maternal βadj = - 0.42, 95% CI - 0.66, - 0.18; paternal βadj = - 0.49, 95% CI - 0.95, 0.03). Associations were still mostly evident, but attenuated after further adjustment for postpartum mental health concurrent with measurement of bonding. CONCLUSIONS: Persistent symptoms of depression or anxiety spanning adolescence and young adulthood predict poorer emotional bonding with infants 1-year postbirth for both mothers and fathers.

ItemModelling timing and tempo of adrenarche in a prospective cohort studyDashti, SG ; Mundy, L ; Goddings, A-L ; Canterford, L ; Viner, RM ; Carlin, JB ; Patton, G ; Moreno-Betancur, M ; Acar, S (PUBLIC LIBRARY SCIENCE, 2022-12-15)To better understand how health risk processes are linked to adrenarche, measures of adrenarcheal timing and tempo are needed. Our objective was to describe and classify adrenal trajectories, in terms of timing and tempo, in a population of children transitioning to adolescence with repeated measurements of salivary dehydroepiandrosterone (DHEA), DHEA-sulphate, and testosterone. We analysed data from the Childhood to Adolescence Transition Study (CATS), a longitudinal study of 1239 participants, recruited at 8-9 years old and followed up annually. Saliva samples were assayed for adrenal hormones. Linear mixed-effect models with subject-specific random intercepts and slopes were used to model longitudinal hormone trajectories by sex and derive measures of adrenarcheal timing and tempo. The median values for all hormones were higher at each consecutive study wave for both sexes, and higher for females than males. For all hormones, between-individual variation in hormone levels at age 9 (timing) was moderately large and similar for females and males. Between-individual variation in hormone progression over time (tempo) was of moderate magnitude compared with the population average age-slope, which itself was small compared with overall hormone level at each age. This suggests that between-individual variation in tempo was less important for modelling hormone trajectories. Between-individual variation in timing was more important for determining relative adrenal hormonal level in childhood than tempo. This finding suggests that adrenal hormonal levels at age 8-9 years can be used to predict relative levels in early adolescence (up to 13 years).

ItemThe role of school connectedness in the prevention of youth depression and anxiety: a systematic review with youth consultationRaniti, M ; Rakesh, D ; Patton, GC ; Sawyer, SM (BMC, 2022-11-25)BACKGROUND: School connectedness reflects the quality of students' engagement with peers, teachers, and learning in the school environment. It has attracted attention from both the health and education sectors as a potentially modifiable protective factor for common mental health problems. However, the extent to which school connectedness may prevent the onset of youth depression or anxiety or promote their remission is unclear. This systematic review examined evidence for prospective relationships between school connectedness and depression and anxiety, and the effect of interventions to improve school connectedness on depression and anxiety. METHODS: We searched MEDLINE, PsycINFO, PubMed, and ERIC electronic databases for peer-reviewed quantitative longitudinal, or intervention studies published from 2011-21 in English examining relationships between school connectedness and anxiety and/or depression. Participants were 14-24 years old when depression and anxiety outcomes were assessed in any education setting in any country. We partnered with five youth advisers (aged 16-21 years) with lived experience of mental health problems and/or the schooling system in Australia, Indonesia, and the Philippines to ensure that youth perspectives informed the review. RESULTS: Our search identified 3552 unique records from which 34 longitudinal and 2 intervention studies were ultimately included. Studies were primarily from the United States of America (69.4%). Depression and anxiety outcomes were first measured at 14 years old, on average. Most studies found a significant protective relationship between higher levels of school connectedness and depressive and/or anxiety symptoms; more measured depression than anxiety. A few studies found a non-significant relationship. Both intervention studies designed to increase school connectedness improved depression, one through improvements in self-esteem and one through improvements in relationships at school. CONCLUSIONS: These findings suggest that school connectedness may be a novel target for the prevention of depression and anxiety. We were not able to determine whether improving school connectedness promotes remission in young people already experiencing depression and anxiety. More studies examining anxiety, diagnostic outcomes, and beyond North America are warranted, as well as intervention trials. TRIAL REGISTRATION: PROSPERO 2021 CRD42021270967.
