Abstract Background A variety of public health measures have been implemented during the COVID-19 pandemic in Canada to reduce contact between individuals. The objective of this study was to provide empirical contact pattern data to evaluate the impact of public health measures, the degree to which social contacts rebounded to normal levels, as well as direct public health efforts toward age- and location-specific settings. Methods Four population-based cross-sectional surveys were administered to members of a paid panel representative of Canadian adults by age, gender, official language, and region of residence during May (Survey 1), July (Survey 2), September (Survey 3), and December (Survey 4) 2020. A total of 4981 (Survey 1), 2493 (Survey 2), 2495 (Survey 3), and 2491 (Survey 4) respondents provided information about the age and setting for each direct contact made in a 24-h period. Contact matrices were constructed and contacts for those under the age of 18 years imputed. The next generation matrix approach was used to estimate the reproduction number (Rt) for each survey. Respondents with children under 18 years estimated the number of contacts their children made in school and extracurricular settings. Results Estimated Rt values were 0.49 (95% CI: 0.29–0.69) for May, 0.48 (95% CI: 0.29–0.68) for July, 1.06 (95% CI: 0.63–1.52) for September, and 0.81 (0.47–1.17) for December. The highest proportion of reported contacts occurred within the home (51.3% in May), in ‘other’ locations (49.2% in July) and at work (66.3 and 65.4% in September and December). Respondents with children reported an average of 22.7 (95% CI: 21.1–24.3) (September) and 19.0 (95% CI 17.7–20.4) (December) contacts at school per day per child in attendance. Conclusion The skewed distribution of reported contacts toward workplace settings in September and December combined with the number of reported school-related contacts suggest that these settings represent important opportunities for transmission emphasizing the need to support and ensure infection control procedures in both workplaces and schools.

The Impact

Background As a result of the novel coronavirus disease 2019 (COVID-19), there have been widespread changes in healthcare access. We conducted a retrospective population-based study in Alberta, Canada (population 4.4 million), where there have been approximately 1550 hospital admissions for COVID-19, to determine the impact of COVID-19 on hospital admissions and emergency department (ED visits), following initiation of a public health emergency act on March 15, 2020. Methods We used multivariable negative binomial regression models to compare daily numbers of medical/surgical hospital admissions via the ED between March 16-September 23, 2019 (pre COVID-19) and March 16-September 23, 2020 (post COVID-19 public health measures). We compared the most frequent diagnoses for hospital admissions pre/post COVID-19 public health measures. A similar analysis was completed for numbers of daily ED visits for any reason with a particular focus on ambulatory care sensitive conditions (ACSC). Findings There was a significant reduction in both daily medical (incident rate ratio (IRR) 0.86, p<0.001) and surgical (IRR 0.82, p<0.001) admissions through the ED in Alberta post COVID-19 public health measures. There was a significant decline in daily ED visits (IRR 0.65, p<0.001) including ACSC (IRR 0.75, p<0.001). The most common medical/surgical diagnoses for hospital admissions did not vary substantially pre and post COVID-19 public health measures, though there was a significant reduction in admissions for chronic obstructive pulmonary disease and a significant increase in admissions for mental and behavioral disorders due to use of alcohol. Conclusions Despite a relatively low volume of COVID-19 hospital admissions in Alberta, there was an extensive impact on our healthcare system with fewer admissions to hospital and ED visits. This work generates hypotheses around causes for reduced hospital admissions and ED visits which warrant further investigation. As most publicly funded health systems struggle with health-system capacity routinely, understanding how these reductions can be safely sustained will be critical.

Objective The objective of this research was to evaluate the impact of federal, public health and social support programs on national suicide rates in Canada. Design Cross-sectional study. Setting Canadian National Database (i.e., Statistics Canada) and Statista. Participants Population-level data, and economic and consumer market data. Main Outcome Measures Suicide mortality data, population data and unemployment data were obtained from available statistical databases (e.g. Statistics Canada). We quantified suicide rate by dividing the total number of suicide deaths by the national population expressed as a rate per 100,000 population. Results Overall suicide mortality rate decreased in Canada from 10.82 deaths per 100,000 in the March 2019 - February 2020 period to 7.34 per 100,000 (i.e. absolute difference of 1300 deaths) in the March 2020 - February 2021 period. The overall Canadian unemployment rate changed from an average monthly rate of 5.7% in 2019 to 9.5% in 2020. Conclusion Our results indicate that for the first post-pandemic interval evaluated (i.e., March 2020 - February 2021), suicide rates in Canada decreased against a background of extraordinary public health measures intended to mitigate community spread of COVID-19. An externality of public health measures was a significant rise in national unemployment rates in population measures of distress. Our results suggest that government interventions that broadly aim to reduce measures of insecurity (i.e., economic, housing, health), and timely psychiatric services, should be prioritised as part of a national suicide reduction strategy, not only during but after termination of the COVID-19 pandemic.

Introduction: Covid-19 was declared a pandemic in March 2020. Since then, governments have implemented unprecedented public health measures to contain the virus. This study will provide evidence to inform responses to the pandemic by: i) estimating population prevalence and trends of self-reported symptoms of Covid-19 and the proportions of symptomatic individuals and household contacts testing positive for Covid-19; ii) describing acceptance and compliance with physical-distancing measures, explore effects of public health measures on physical, mental and social wellbeing; iii) developing a mathematical network model to inform decisions on the optimal levels of physical distancing measures. Methods: Two cross-sectional nationally-representative telephone surveys will be conducted in Ireland using random digit-dialling, with response rates estimates based on proportion of non-operational and non-answering numbers. The first survey with four waves in May and June will address adherence to social distancing measures and whether the respondent or other household members are or have been unwell during the preceding two weeks with one or more symptoms of Covid-19. The second survey with three waves in June, July and September will address knowledge, attitudes, and compliance towards physical-distancing measures and physical, mental and social wellbeing. The mathematical network model will be developed for all-Ireland (on various levels of spatial granularity including the scale of counties and electoral divisions) based on outputs from both cross-sectional surveys and relevant publicly available data to inform decisions on optimal levels and duration of physical distancing measures. Discussion: This study will contribute to our understanding of the impact and sustainability of public health measures of the Covid-19 pandemic. Findings will have long-lasting benefits, informing decision-making on the best levels, and duration of physical-distancing measures, balancing a range of factors including capacity of the health service with the effects on individuals’ wellbeing and economic disruption. Findings will be shared with key policy-makers.

Abstract Background Summary statistics comparing the stage at diagnosis of geographically defined populations of cancer patients are increasingly used in public reporting to monitor geographical inequalities but may be confounded by patient case mix. We explore the impact of case-mix adjustment on a publicly reported measure of early stage at diagnosis in England. Methods We analyzed data used for publicly reported statistics about the stage of patients diagnosed with 1 of 11 solid tumours in 2015 in England, including information on cancer site (bladder, breast, colon, rectum, kidney, lung, melanoma, non-Hodgkin lymphoma, ovarian, prostate, endometrial), age, gender, income deprivation and population-based commissioning organization. We investigated how cancer site and other patient characteristics influence organizational comparisons and attainment of early-stage targets (≥60% of all cases diagnosed in TNM stages I–II). Results Adjusting for patient case mix reduced between-organization variance by more than 50%, resulting in appreciable discordance in organizational ranks (Kendall’s tau = 0.53), with 18% (37/207) of organizations being reclassified as meeting/failing the early-stage target due to case mix. Conclusion Summary statistics on stage of cancer diagnosis for geographical populations currently used as public health surveillance tools to monitor organizational inequalities need to account for patient sociodemographic characteristics and cancer site case mix.

The Impact

During the COVID-19 pandemic, the government in Kuwait implemented public health measures to control the spread of the virus. However, despite the importance of these restrictions, normal activities related to purchasing of groceries, concerns related to food safety, and overall uncertainty may have influenced food behaviors and food consumption. Hence, the study investigates the impact of COVID-19 on food purchasing behaviors, eating behaviors, and the perception of food safety and security among residents in Kuwait. A cross-sectional study was carried out using self-administered questionnaires between 28 July 2020 and 31 August 2020 during the COVID-19 pandemic in Kuwait. A total of 841 respondents participated in the study. The study identified several changes in food purchasing behaviors, eating behaviors, food consumption, and consumers perceptions on food safety during the pandemic. The closures, restrictions, and changes in food purchasing evidently influenced individual’s eating behaviors. Largely, participants were found to (i) change their food purchasing behavior (74%); (ii) opt for online food delivery services (42.8%); (iii) purchase long-shelf-life foods (e.g., canned food and dry staples) (76%); (iv) consume more meals at home (76%); and (v) follow public health measures to reduce the spread of the virus and ensure their safety (98%). This study indicates that individuals during times of uncertainty and stress change their food purchasing behaviors, food consumption habits, and follow guidelines and recommendations. These findings may help public health initiatives to focus on raising awareness about the importance of health, wellbeing, and nutrition during times of crises.

Abstract Objectives The effectiveness of public health interventions for mitigation of the COVID-19 pandemic depends on individual attitudes, compliance, and the level of support available to allow for compliance with these measures. The aim of this study was to describe attitudes and behaviours towards the Canadian COVID-19 public health response, and identify risk-modifying behaviours based on socio-demographic characteristics. Methods A cross-sectional online survey was administered in May 2020 to members of a paid panel representative of the Canadian population by age, gender, official language, and region of residence. A total of 4981 respondents provided responses for indicators of self-reported risk perceptions, attitudes, and behaviours towards COVID-19 public health measures. Results More than 90% of respondents reported confidence in the ability to comply with a variety of public health measures. However, only 51% reported preparedness for illness in terms of expectation to work if sick or access to paid sick days. Risk perceptions, attitudes, and behaviours varied by demographic variables. Men, younger age groups, and those in the paid workforce were less likely to consider public health measures to be effective, and had less confidence in their ability to comply. Approximately 80% of respondents reported that parents provided childcare and 52% reported that parents in the workforce provided childcare while schools were closed. Conclusion Policies to help address issues of public adherence include targeted messaging for men and younger age groups, social supports for those who need to self-isolate, changes in workplace policies to discourage presenteeism, and provincially co-ordinated masking and safe school policies.

ABSTRAKStunting yaitu keadaan gagal tumbuh akibat dari kekurangan gizi kronis. Prevalensi stunting di Kabupaten Tasikmalaya menempati urutan keempat, dimana kecamatan Sukahening menempati urutan pertama tertinggi dengan jumlah 155 balita mengalami stunting. Faktor yang dapat mempengaruhi kejadian stunting yaitu pengasuhan anak yang kurang baik dimana tidak diberikannya ASI secara Ekslusif. Pencegahan stunting yaitu pada 1000 hari kehidupan dimana salah satunya pemberian ASI secara Ekslusif.Penelitian ini bertujuan untuk mengetahui hubungan antara pemberian ASI Ekslusif dengan kejadian stunting pada balita 1-5 tahun di Puskesmas Sukahening Kecamatan Sukahening Kabupaten Tasikmalaya.Jenis Penelitian yang digunakan adalah deskriptif korelasional dengan pendekatan cross-sectional. Populasi total sampling sebanyak 95 responden menggunakan teknik purposive sampling.Hasil Penelitian diperoleh lebih dari setengah responden 51,6% tidak diberikan ASI secara Ekslusif, dan sebagian besar 65,3% balita mengalami stunting. Hasil perhitungan chi-square diperoleh ρ.value (0,000<0,05) maka H0 ditolak sehingga terdapat hubungan antara Pemberian ASI Ekslusif dengan kejadian stunting pada balita 1-5 tahun di Puskesmas Sukahening Kecamatan Sukahening Kabupaten Tasikmalaya.Hasil penelitian ini diharapkan dapat memberi informasi yang bermanfaat dan perlu dilakukan pendidikan kesehatan ulang yang terjadwal terkait nutrisi yang terjangkau dan sehat sehingga dapat meningkatkan cakupan ASI Ekslusif dan dapat menurunkan angka stunting.Kata Kunci : ASI Ekslusif, StuntingDaftar Pustaka : 25 buku (2010-2018)9 jurnal (2013-2019)2 Website (2010-2017) ABSTRACTStunting is a condition of growth failure due to chronic malnutrition. The stunting prevalence in Tasikmalaya Regency was at the fourth place where Sukahening sub-district was at the highest with 155 stunting. Factor that can influence the occurrence of stunting is a poor parenting where exclusive breastfeeding is not given. The best prevention of stunting is on 1000 days of life where exclusive breastfeeding is given. The impact, if the baby is not given exclusive breastfeeding, they will lack of nutrition and also will have an impact on the growth or inappropriate height. This aims of the research is to determine the relationship between exclusive breastfeeding and the incidence of stunting on toddler under 5 years of at Sukahening Public Health Center, Sukahening Sub district, Tasikmalaya Regency. The type of research used is descriptive correlation with a cross-sectional approach. The total samplings were 95 respondents which used purposive sampling technique. The results of the research were obtained more than half of the respondents 51.6% were given exclusive breastfeeding, and most 65.3% of children under five had stunting. The chi-square calculation results obtained that ρ.value (0,000 <0,05) then H0 is rejected so that there is a relationship between exclusive breastfeeding and the incidence of stunting on toddlers under 5 years in Sukahening Public Health Center, Sukahening Sub district, Tasikmalaya Regency. Performed the health education related to affordable and healthy nutrition so that it can increase the coverage of exclusive breastfeeding and can reduce stunting rates.
