The change in the prevalence of HHD

At the global level, the prevalence of HHD increased by 137.91% from 7.82 million in 1990 to 19.60 million in 2019 (Fig.1A, Table S1). The prevalence rate went up year by year, while the ASPR was relatively stable (Fig. 1C). The ASPR was 233.77 (95% UI=170.52312.9) per 100,000 population in 2019, which increased slightly compared with that in 1990 with an EAPC of 0.17 (95% UI=0.150.18) (Fig. 1C, Tables S2 and S3). Compared with the ASPR trend of the female subjects (EAPC, 0.28, 95% UI=0.260.30), the trend of the male subjects was more stable during the study period (EAPC, 0.02, 95% UI=0.000.04, Table S3).

HHD occurred mostly in people aged over 65 (Fig. S1A). We also found that the ASPR increased with age growth for both men and women in 1990 and 2019. The female prevalence rate was much higher than male in people aged over 80 during 2019, yet there was a similar prevalence rate for aged men and women in 1990 (Fig.2).

Among 25 GBD regions, top three regions with the highest prevalence cases were Asia, East Asia, and America. In addition, the three regions with the highest ASPR were East Asia (426.15, 95% UI=306.64574.76), Oceania (344.91, 95% UI=248.54477.87), and Southeast Asia (334.77, 95% UI=244.81451.58) (Table S4). At the national level, China carried the highest HHD prevalence, followed by the United States of America and India (Fig. S2A). The highest ASPR of HHD occurred in Cook Islands, Jordan, Kuwait and Seychelles (Fig. S2C).

A total of 1.16 (95% UI=0.861.28) million people were estimated to experience HHD associated deaths worldwide in 2019, which increased from 0.65 (95% UI=0.530.73) million death cases in 1990 (Table S1). The ASDR in females was 15.05 (95% UI=11.5117.09) per 100,000 population in 2019, which was moderately higher than that in males (14.95, 95% UI=10.3216.75) (Table S2). Although the number of HHD deaths grew up dramatically during 19902019, the trend of death rate was relatively stable and the global ASDR declined with a negative value of EAPC (0.74, 95% UI=-0.92--0.58) (Fig. 1D, E, and F, Table S3). Meanwhile, the male and female ASDR shared a similar trend (EAPC for men, 0.72, 95% UI=-0.95--0.50; EAPC for women, 0.79, 95% UI=-0.93--0.65).

For both men and women, age-specific distribution of death rate remained stable in 1990 and 2019 (Fig. 2). Like HHD prevalence, people aged over 65 were more likely to suffer HHD deaths (Fig. S1B).

At the regional level, Central Sub-Saharan Africa, Eastern Sub-Saharan Africa, North Africa and Middle East had the highest ASDR; Australasia, high-income Asia Pacific and Eastern Europe were the three regions with the lowest ASDR (Table S5). At the national level, China carried the highest HHD death burden, followed by India and the Untied States of America (Fig. S2D). Bulgaria, Afghanistan, and Central African Republic were the three countries with highest ASDR (Fig. S2F).

A total of 21.50 (95% UI=16.4023.90) million DALYs were estimated on a global scale in 2019, and 13.94 (95% UI=11.3115.65) DALYs in 1990 (Table S1). There was a consistent rise in DALY number (Fig. 1G). However, DALY rate declined between 1990 and 2005, then ascended during 20062019 (Fig. 1H). In addition, it shown a persistent decline for the age-standardized DALY rate over the 30years (Fig. 1I).

The age-standardized DALY rate in men was 277.86 (95% UI=199.58311.14) per 100,000 population in 2019, which was higher than that in women (256.81, 95% UI=205.22291.98) (Table S2). The DALY rate distribution for males and females in 2019 was similar to that in 1990 (Fig. 2). In 2019, the age-specific trends of DALY rate attributed to HHD were similar for both sexes.

On the observation of the regions scale, Central Sub-Saharan Africa, Eastern Sub-Saharan Africa, and Oceania were the three regions with the highest age-standardized DALY rates (Table S5). It revealed a considerable national disparity in the burden of HHD. DALY numbers varied more than 10-fold between countries (Fig.3A). China had the highest HHD DALY number, followed by India and Indonesia (Fig. 3D). After adjusting population, Bulgaria, Estonia, and Cook Islands were the three countries with the highest rate of DALYs (Fig. 3B and E). After adjusting for age and population, Afghanistan, Cook Islands, and Central African Republic had the highest age-standardized DALY rates (Fig. 3C and F).

The drift of HHD-related ASPR, ASDR, and age-standardized DALYs rate among five SDI quintiles were presented in Fig.4. The ASPR of HHD was highest in the middle SDI region, and the lowest in the high SDI region between 1990 and 2019 (Fig. 4A). It was interesting to note that, as opposed to the regions with other SDI, the middle SDI region presented a descending trend of ASPR (EAPC, 0.24, 95% UI=-0.2--0.20) (Table S3). ASDR and age-standardized DALY rate decreased the fastest in the middle SDI region (EAPC, 1.58, 95% UI=-1.98--1.20 for ASDR; EAPC, 1.74, 95% UI=-2.11--1.41 for age-standardized DALY rate) (Table S3, Fig. 4B and C). In the middle SDI region, the trend of ASDR and age-standardized DALY rate presented undulating curves (Fig. 4B and C). Compared with a downward trend for females (EAPC, 0.28, 95% UI=-0.4--0.11), male age-standardized DALY rate showed an upward tendency in the high SDI region (EAPC, 0.34, 95% UI=0.110.57).

The age-standardized prevalence, death, and DALY rate for hypertensive heart disease by different SDI regions, 19902019. ASPR, age-standardized prevalence rate; ASDR, age-standardized death rate; DALY, disability adjusted life-year; SDI, socio-demographic index

ASPR, ASDR, and age-standardized DALY rate of HHD stratified by SDI were shown in Fig.5. ASPR of HHD rose before SDI value of 0.4 and then start to decrease (Fig. 5A). There was a negative and significant Pearsons correlation between HHD disease burden and SDI (r=0.74, 95% CI=-0.77--0.70, p<0.001, for age-standardized DALY rate; r=0.70, 95% CI=-0.74--0.66, p<0.001, for ASDR) (Fig. 5C). The univariate linear regression indicated that many socioeconomic variables (HDI, IHDI, SDI, HAQ, population with at least some secondary education, life expectancy, and physicians per 10,000 people) had a significantly negative correlation with age-standardized DALY rate (all p<0.001, Table1).
