まとめ
持続的貧困は、特に黒人男性において、前立腺がん死亡率の上昇と関連しています。前立腺がんの予後におけるこれらの格差は、根深い社会経済的および人種的格差を浮き彫りにし、時間の経過とともに持続しています。
科学分野:
- 公衆衛生
- 疫学
- 健康格差
背景:
- 人種的および社会経済的要因は、前立腺がん死亡率に大きく影響します。
- 持続的貧困と人種が前立腺がん死亡率に与える複合的な影響は、十分に研究されていません。
研究 の 目的:
- 持続的貧困と人種が、米国郡における前立腺がん特異的死亡率にどのように関連しているかを調査すること。
- 持続的貧困に関連して、前立腺がん死亡率における人種間格差が時間とともに変化したかどうかを判断すること。
主な方法:
- 年齢調整前立腺がん死亡率について、監視、疫学、および最終結果(SEER)プログラムのデータ(1999-2020年)を利用しました。
- 死亡率データを、米国農務省の郡レベルの持続的貧困分類(30年間で貧困率20%以上)とリンクさせました。
- 地域、都市状況、年を調整した四分位点回帰分析を使用し、貧困、人種、および時間の相互作用項を分析しました。
主要な成果:
- 郡における持続的貧困は、前立腺がん死亡率の上昇と有意に関連していました。
- 黒人男性は、白人男性と比較して、郡レベルでの死亡率が有意に高いことが示されました。
- 持続的貧困と人種との相互作用は有意であり、貧困郡における黒人と白人の死亡率格差を拡大させました。
結論:
- 持続的貧困は、前立腺がん死亡率の増加と人種間格差の拡大に関連しています。
- 前立腺がんにおける人種間の死亡率格差は、全体的な低下にもかかわらず、持続的貧困郡において一貫してより大きいままでした。
- 構造的な社会経済的および人種的格差は、集団レベルの前立腺がんの予後に大きな影響を与えます。

Cancer Survival Analysis
805
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...

The Tumor Microenvironment
8.0K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

Longitudinal Research

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Surveys

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Close Relationships and Culture

Culture shapes how people approach attraction, choose partners, and build long-term relationships. While some preferences in mate selection appear consistent across cultures, such as men valuing physical attractiveness and women emphasizing financial resources, cultural contexts influence how these preferences are expressed and prioritized. Marriage extends beyond romantic ideals in many societies and is deeply embedded in social, economic, and religious frameworks.The Role of Culture in Mate...

Cancer Prevention
8.4K
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.
