BACKGROUND Life expectancy in China has been improving markedly but health gains have been uneven and there is inequality in survival chances between regions and in rural as against urban areas. This paper applies a statistical modelling approach to mortality data collected in conjunction with the 2000 Census to formally assess spatial mortality contrasts in China. The modelling approach provid...

Actuaries and demographers have a long tradition of using collateral data to improve mortality estimates. Three main approaches have been used to accomplish the improvement — mortality laws, model life tables, and relational methods. The present paper introduces a regression model that incorporates all of the beneficial principles from each of these approaches. The model is demonstrated on mort...

objective: multiple sclerosis (ms) is a disease with a detrimental effect on functional status. the present study investigated the effect of a sexual therapy program on the quality of life (qol) of women with multiple sclerosis. method: women with multiple sclerosis and sexual dysfunction (n = 30) were selected, and were randomly assigned into the treatment (n = 15), or the control groups (n = ...

BACKGROUND Diagnosing a potentially life-threatening disease may adversely affect patient quality of life (QOL) independent of biologic effects. It is unknown whether the mere diagnosis of Barrett's esophagus (BE) adversely impacts patients' preferences (health-state utility) sufficiently to impair the cost-effectiveness of endoscopic screening for esophageal adenocarcinoma. GOAL To calculate...

model life tables are a key methodological tool for the study of mortality, especially in countries where statistics are incomplete. the tables published by the united nations in 1982 paved the way for considerable progress in this field. now that more complete and reliable data are available, the use and interpretation of these tables can be critically assessed. zhongwei zhao shows here that m...

OBJECTIVES This report presents complete period life tables by Hispanic origin, race for the non-Hispanic white and non-Hispanic black populations, and sex for the United States based on age-specific death rates in 2006. METHODS The methods used to estimate the probability of death for ages 0-80 for the Hispanic population and 0-65 for the non-Hispanic white and non-Hispanic black populations...

aim and background: this study reviewed the effectiveness of self-control training on quality of life in patients with multiple sclerosis (ms). to do so, 40 patients with ms were selected through convenient sampling method among the study subjects with multiple sclerosis recorded in ardabil in 2012 (estimation: n = 350). methods and materials: this was a clinical trial designed as pretest postt...

OBJECTIVE Despite improving healthcare, the gap in mortality between people with serious mental illness (SMI) and general population persists, especially for younger age groups. The electronic database from a large and comprehensive secondary mental healthcare provider in London was utilized to assess the impact of SMI diagnoses on life expectancy at birth. METHOD People who were diagnosed wi...

In this article, the biology and fertility life table parameters of the cabbage aphid, Brevicoryne brassicae (L.) (Hemiptera: Aphididae), were studied on cauliflower leaves, Brassica oleracea var. botrytis (Brassicales: Brassicaceae), of the cultivars Smilla, Snow mystique, White cloud, Buris, Galiblanka, Snow crown, SG, and Tokita. This study was conducted under controlled conditions: 25 ± 2°C...
