Did you know that past smoking behavior can make an older adult nearly twenty times more likely to develop cancer? This study reveals the hidden health crisis in India's North-East. The North-eastern region of India faces a unique challenge with higher rates of substance use compared to other areas.

Understanding how these habits link to non-communicable diseases is critical for creating effective prevention strategies. Globally, non-communicable diseases affect forty-one million people annually and account for seventy-one percent of all deaths. Low and middle-income countries bear the brunt, accounting for eighty-five percent of premature deaths from these conditions.

In India, over two hundred sixty-six million adults use tobacco daily, representing twenty-eight point six percent of the population. The North-eastern area specifically displays the highest prevalence of tobacco use among all states in the country. This research draws data from the Longitudinal Ageing Study in India, Wave One, conducted between two thousand seventeen and eighteen.

The dataset includes thirty-one thousand four hundred sixty-four older adults aged sixty and older across thirty-five Indian states. The specific sample for this study consisted of four thousand one hundred fifty-five individuals from the North-eastern states. Most participants lived in rural areas, and the majority identified as Christian, followed by Hindus.

This figure maps the prevalence of non-communicable diseases among adults aged sixty and above across eight North-Eastern Indian states in 2017–18. The authors report that Sikkim shows a prevalence of sixty-five point eight nine percent, while Nagaland reports twenty-one point two nine percent.

These data points highlight significant regional disparities in disease burden within this specific demographic group. Table 2 presents the prevalence of various non-communicable diseases among older adults in North-eastern India, broken down by background characteristics such as sex, age, and place of residence.

The data reveals that hypertension is a widespread condition across all groups, with rates reaching forty-seven point six eight percent in those aged seventy-five and above. Additionally, the table highlights significant disparities based on location, showing an overall prevalence of sixty-one point four five percent for any NCD in urban areas compared to forty-two point four five percent in rural settings.

Figure 2 presents the proportion of older adults aged sixty and above suffering from various non-communicable diseases who have a history of tobacco consumption. The chart highlights that among these conditions, lung diseases show the highest association at sixty-nine point four nine percent, while high cholesterol shows the lowest at thirty-six point three six percent.

These data points illustrate the significant overlap between past smoking behaviors and specific chronic health outcomes in this demographic. Figure 3 displays the percentage of older adults aged sixty and above who have a history of alcohol consumption across various non-communicable diseases.

The chart highlights that stroke has the highest association with past alcohol use at thirty-six point seven three percent, followed by lung diseases at twenty-seven point one two percent. These findings suggest a notable link between historical drinking behaviors and specific chronic health conditions in this demographic.

Table 3 presents binary logistic regression results examining the association between substance consumption and non-communicable diseases among older adults in North-eastern India. The authors report odds ratios for conditions like hypertension, diabetes, and cancer based on behaviors such as smoking or alcohol use, adjusted for physical activity and socio-economic variables.

For instance, the table indicates an odds ratio of nineteen point seven nine nine for smokers regarding cancer risk compared to non-smokers. These statistics help quantify how specific lifestyle factors correlate with disease prevalence in this demographic.

Perhaps the most striking finding is that the chances of having cancer are nineteen point eight times higher if an individual has past smoking behavior. Additionally, neurological and psychiatric diseases are three point five six times more likely in former smokers compared to non-smokers.

Current smokers face a two point one six times higher odds of suffering from stroke compared to those who do not smoke. Those currently consuming alcohol have a one point eight seven times higher odds of developing heart disease. Socioeconomic factors play a role, as older adults with better economic conditions and more education are less likely to use substances.

Men exhibit a higher likelihood of using nearly all categories of substances compared to women in this demographic. The study concludes that substance use is highly associated with non-communicable diseases in the North-eastern region's older adult population.

High tobacco and alcohol use among people over sixty with chronic diseases like cardiovascular issues is described as alarming. Substance use is a massive driver of chronic disease in this region, with urban areas hit hardest. Preventive strategies targeting tobacco and alcohol are urgently needed to protect aging populations.
