  • Worldwide trends in underweight and obesity from 1990 to 2022

    Open AccessNowell H Phelps, Rosie Singleton et al.ARTICLEThe Lancet2024

    BACKGROUND: Underweight and obesity are associated with adverse health outcomes throughout the life course. We estimated the individual and combined prevalence of underweight or thinness and obesity, and their changes, from 1990 to 2022 for adults and school-aged children and adolescents in 200 countries and territories. METHODS: ). For school-aged children and adolescents, we report thinness (BMI 2 SD above the median). FINDINGS: From 1990 to 20…

  • Causes of blindness and vision impairment in 2020 and trends over 30 years, and prevalence of avoidable blindness in relation to Vision 2020

    Open AccessJaimie D Steinmetz, Rupert R A Bourne et al.ARTICLEThe Lancet Global Health2021

    BACKGROUND: Many causes of vision impairment can be prevented or treated. With an ageing global population, the demands for eye health services are increasing. We estimated the prevalence and relative contribution of avoidable causes of blindness and vision impairment globally from 1990 to 2020. We aimed to compare the results with the World Health Assembly Global Action Plan (WHA GAP) target of a 25% global reduction from 2010 to 2019 in avoidab…

  • Worldwide trends in hypertension prevalence and progress in treatment and control from 1990 to 2019

    Open AccessBin Zhou, Rodrigo M Carrillo-Larco et al.ARTICLEThe Lancet2021

    BACKGROUND: Hypertension can be detected at the primary health-care level and low-cost treatments can effectively control hypertension. We aimed to measure the prevalence of hypertension and progress in its detection, treatment, and control from 1990 to 2019 for 200 countries and territories. METHODS: We used data from 1990 to 2019 on people aged 30-79 years from population-representative studies with measurement of blood pressure and data on blo…

  • Trends in prevalence of blindness and distance and near vision impairment over 30 years

    Open AccessRupert Bourne, Jaimie D Steinmetz et al.ARTICLEThe Lancet Global Health2021

    BACKGROUND: To contribute to the WHO initiative, VISION 2020: The Right to Sight, an assessment of global vision impairment in 2020 and temporal change is needed. We aimed to extensively update estimates of global vision loss burden, presenting estimates for 2020, temporal change over three decades between 1990-2020, and forecasts for 2050. METHODS: We did a systematic review and meta-analysis of population-based surveys of eye disease from Janua…

  • Stimulus Change in Extinction of a Blocked Response

    Open AccessL J Martin, Jack I Bradley et al.ARTICLEPsychological Reports1974

    Influences of the partial reinforcement effect due to changes in visual stimuli at the onset of extinction were evaluated. Following blocking of the learned response, changes in stimuli in the apparatus reduced perseveration during extinction. The greatest effect was observed when a single stimulus change occurred. Redundant changes had progressively reduced influence
