To evaluate tuberculosis (TB) incidence rates and trends over a period of 20 years (1991-2010) and assess the impact of the National TB Control Program (NTP) on incidence trends.
This is a retrospective study of TB surveillance data reported by the Ministry of Health. We evaluated TB incidence data by nationality, age, and region of the country and assessed incidence trends over 20 years of study. Chi-squared test was used to assess trend change and its significance.
There were a total of 64,345 reported TB cases over the study period. Of these 48% were Non-Saudis. TB annual incidence rate ranged between 14 and 17/100,000. For Saudis, the rate ranged between 8.6 and 12.2/100,000. Non-Saudis had 2-3 times higher incidence. Disease trend was rising over the first 10 years of the study period then it started to fall slightly. The incidence increased with age, but only people older than 45 years showed a declining trend. Regional variations were observed. Makkah and Jazan regions had the highest incidence rates. Disease trends were rising over the last 10 years in Makkah and Central regions.
TB control seems to be facing some challenges in several regions of the Kingdom. NTP needs to evaluate and improve TB control strategies in order to reduce disease incidence to elimination levels.
评估 20 年来（1991-2010 年）结核病（TB）的发病率和趋势，并评估国家结核病控制规划（NTP）对发病率趋势的影响。
这是一项对卫生部报告的结核病监测数据进行的回顾性研究。我们按国籍、年龄和国家地区评估了结核病发病率数据，并评估了 20 年研究期间的发病率趋势。采用卡方检验评估趋势变化及其意义。
在研究期间，共报告了 64345 例结核病病例。其中 48%是非沙特人。结核病年发病率在 14 至 17/10 万之间。沙特人的发病率在 8.6 至 12.2/10 万之间。非沙特人的发病率是沙特人的 2-3 倍。疾病趋势在研究的前 10 年呈上升趋势，然后开始略有下降。发病率随年龄增长而增加，但只有 45 岁以上的人呈下降趋势。观察到地区差异。麦加和吉赞地区的发病率最高。在过去 10 年中，麦加和中部地区的疾病趋势呈上升趋势。
王国的一些地区的结核病控制似乎面临一些挑战。NTP 需要评估和改进结核病控制策略，以将发病率降低到消除水平。
