Background
Japan’s ‘Health Japan 21’ initiative targets a reduction in adult smoking prevalence to 12% by 2032. This study evaluates the probability of meeting this target at both national and prefectural levels by estimating and comparing prevalence trends.
Method
Using crude smoking prevalence data from 2001 to 2022 for the whole nation and acro...
While male breast cancer (MBC) remains a rare and understudied disease, comparatively little is known about its prognosis in contrast to female breast cancer (FBC). There is a paucity of large population‐based studies comparing the prognosis of MBC patients to FBC patients in Japan. This study analyzed 181,540 breast cancer cases, 1058 (0.6%) males...
Importance
Although evaluation of geographic area inequities in vaccination is crucial to identify areas that need community-based interventions, knowledge of disparities in human papillomavirus (HPV) vaccination uptake remains limited in Japan.
Objective
To investigate the association of female cumulative HPV vaccination uptake with neighborhood-...
Adult primary brain and central nervous system (CNS) cancers, though comprising only about 4% of new cancer diagnoses, significantly impact morbidity and mortality due to their low survival rates. Globally, brain and CNS tumor incidence varies considerably, with the United States exhibiting one of the highest rates and Japan among the lowest worldw...
Despite the importance of genetic testing for risk assessment and treatment in breast cancer, the prognostic impact of germline pathogenic variants (PVs), especially in Asian populations, is unclear. We assessed the impact of germline PVs in patients with early‐stage breast cancer. This study included 7278 Japanese multihospital registry patients....

Background
The Japanese 2020 cervical screening guidelines recommend conventional cervical cytology screening every 2-years for women aged 20–69 years. The nonavalent human papillomavirus (HPV) vaccine has also recently been approved in Japan. We therefore evaluated the cost-effectiveness of cervical cancer screening strategies alongside universal...
Background
Due to the lack of a national mortality inequality monitoring framework, the overall picture in Japan remains unclear. Here, we investigated educational inequalities in mortality and their cause-specific contribution in Japan.

Introduction
In Japan, heated tobacco products (HTPs) are promoted by the tobacco industry as reduced-risk tobacco products despite the lack of evidence for this claim. This study determined the distribution of HTP-harmfulness perception and identify the explanatory factors associated with the perception of HTP as less harmful than conventional cig...
"Tobacco harm reduction" is defined as a method to minimize harm and risk of death and disease without eliminating tobacco and nicotine use. In Japan, where heated tobacco products (HTPs) are prevalent, the tobacco industry is progressively endorsing the concept of "tobacco harm reduction." Therefore, stakeholders in tobacco control must urgently s...
Advances in diagnostic techniques and treatment modalities have impacted head and neck cancer (HNC) prognosis, but their effects on subsite‐specific prognosis remain unclear. This study aimed to assess subsite‐specific trends in mid‐ and long‐term survival for HNC patients diagnosed from 1993 to 2011 using data from population‐based cancer registri...

Objective:
Although there is increasing evidence to suggest the cost-effectiveness of aspirin use to prevent colorectal cancer (CRC) in the general population, no study has assessed cost-effectiveness in patients with familial adenomatous polyposis (FAP), who are at high risk of developing CRC. We examined the cost-effectiveness of preventive use...
Background: Hyogo Prefecture has managed smoking ban legislation with partial restrictions in public places (Hyogo-L) since 2013. Previous studies have reported a significant decrease in admissions for acute coronary syndrome (ACS) in Kobe-city, but not in other districts of Hyogo Prefecture in the 2 years after Hyogo-L. The aim of the present stud...
Characterizing trends in mortality rates with consideration of trends in incidence rates at the population level could help identify unmet needs in public health and provide essential indicators of cancer control. In the late 20th century, the arrival of the first molecular targeted agent, rituximab, for non-Hodgkin lymphoma (NHL) led to a paradigm...
Cancer in children, adolescents, and young adults (AYAs) although rare, is the leading disease-specific cause of death in Japan. This study aims to investigate cancer incidence and type of treatment hospital among children and AYAs in Japan.

In most high-resource countries with organized screening programs, the incidence and mortality of cervical cancer is decreasing. Recent statistics have also revealed a reduction in invasive cervical cancer incidence as a result of national vaccination programs. Paradoxically, cervical cancer incidence has increased in Japan, particularly amongst wo...
Objectives
Promoting smoke-free policies is a key intervention for reducing secondhand smoke (SHS) exposure. During the COVID-19 pandemic in Japan, many indoor smoking spaces in workplaces were closed. This study aimed to reveal the association between a workplace smoke-free policy and SHS exposure among non-smoking employees, distinguishing betwee...
Continued decrease in smoking prevalence and increasing use of sensitive diagnostic procedures necessitate updated monitoring of trends in lung cancer incidence in Japan. We analyzed histology‐ and stage‐specific trends in 1993 to 2015 using data from 62 870 diagnosed cases from the Monitoring of Cancer Incidence in Japan project. After applying a...

Questions
Questions (2)
I want to conduct path analysis with logistic regression model.
Exposure variables are continuous (body weights at different time points), and mediator variables are also continuous (age etc.).
Outcome is dichotomous variable (existence of a disease).
My interests are the direct and indirect effects of exposure variables on the outcome. So I am trying to do path analysis with logistic regression model.
I use SAS, but I could not find how to apply logistic model with PROC CALIS.
Are there any options to select logistic model? or some other procedures?
This may be done by conducting several regression analyses and re-calculating the output coefficients, but I want to avoid self calculation.
Some websites say it can be done by Mplus. Is it an easier way to use Mplus?
I am looking for a standard way to calculate risk-factor-specific incidence rate from overall population incidence rate. The available data are overall population incidence rate of a disease, prevalence of a risk factor, and relative risk of that disease according to the risk factor. What I want to do is to estimate the incidence rate of people with or without that risk factor. My image is to allocate the overall incidence rate into two groups (risk factor holders and non-holders), keeping consistency with the overall incidence rate. Are there any good references?
