How’s that New Year’s resolution going?

About one in four Americans planned to set a New Year’s resolution heading into 2022, according to a recent Economist/YouGov poll. The most common themes included: living healthier (23%), personal improvement or happiness (21%), and losing weight (20%). When it comes to follow-through, a majority of people are confident that they will be able to achieve their resolutions. Despite this commitment however, only 55% of resolvers stick to their resolution for a full month, according to a study published in the Journal of Substance Abuse. After 6 months, that figure drops to 40%, and by 24 months, 19% report that they successfully stuck to their resolutions.

This got us wondering—what does Hello Heart data tell us about New Year’s resolutions? So our data science team began analyzing aggregated, anonymized data from 12,329 Hello Heart users from Nov 2020 to March 2021 to look for changes, trends, and improvements in key user metrics. Users were grouped into cohorts based on their age, gender, and area deprivation index (ADI).

Fact: More people die of heart-related causes during the Christmas holidays than any other time of year.

A survey by the National Alliance of Mental Illness (NAMI) showed 63% percent of people report feeling too much pressure during the holiday season. A 2016 study conducted by Journal of the American Heart Association found that 4.2% more people die from cardiac events outside of a hospital between Dec. 25 and Jan. 7 than any other time of year. In fact, this “Christmas holiday effect” is observed in countries worldwide. In 2021, a large-scale Norwegian study found elevated death rates connected to cardiovascular disease during the Christmas holiday period. Similar patterns were reported in Sweden and Canada as well.

Personal health takes a backseat during the holidays

While the Christmas holidays are perhaps the most critical time of the year to monitor one’s heart health, we see a dip from November to December in the number of times Hello Heart users log into the Hello Heart app. The chart below shows the % change in app sessions from one month to the next between November 2020 and March 2021. In December, session volume decreased 10% to 30% depending on age group—presumably a reflection of the unique changes in stress and behavior during the holiday season.

New Year’s resolutions drive sustained increases in Hello Heart usage

While the holidays bring a relaxed focus on health, the New Year ushers in the promise of a fresh start and a renewed commitment to being one’s best self. In the chart above, January saw a 20-80% increase in app sessions compared to December—a statistically significant jump (p<0.01) across all age groups. Users under 35 years-old saw the most substantial increase in app sessions while each older age group saw progressively smaller increases—a real-world confirmation of studies that show younger people are more likely to commit to New Year’s resolutions.

Although some age groups show slight decreases in Hello Heart usage following January, engagement with the Hello Heart app remains higher into February and March compared to pre-January levels.

Socioeconomic status & blood pressure monitoring frequency

Our next chart shows the average number of monthly blood pressure readings for users between November 2020 and March 2021, grouped by Area Deprivation Index (ADI). According to The Center for Health Disparities Research at the University of Wisconsin's School of Medicine & Public Health, ADI “allows for rankings of neighborhoods by socioeconomic disadvantage.” ADI considers factors including income, education, employment, and housing quality, and “can be used to inform health delivery and policy, especially for the most disadvantaged neighborhood groups.”

High ADI corresponds to socioeconomically disadvantaged groups while low ADI signifies groups that are more well off in comparison.

Disadvantaged groups use Hello Heart to monitor blood pressure more than advantaged groups

Similar to the first chart, we see a dip in the number of blood pressure readings from November to December across all but one ADI group. However, in January 2021 all ADI groups surpassed the average number of blood pressure readings from the previous two months. Interestingly, while users recorded about 1 less BP reading in February compared to January, both February and March 2021 saw higher levels of blood pressure monitoring across all groups compared to November and December 2020. Hello Heart data shows that high and High-Mid ADI groups perform more blood pressure readings in most months compared to Low and Low-Mid ADI groups.

But why?

Digital health solutions can help address the “wealth-health” gap

It’s no secret that socioeconomically disadvantaged people face an uphill battle in the US healthcare system—from poor access to high-quality affordable healthcare to a higher prevalence of cardiovascular disease and other heart-related conditions, including hypertension, arrhythmia, and hyperlipidemia according the National Institutes of Health.

Convenient, easy-to-use, and proven-effective solutions like Hello Heart may be helping employers bridge the “wealth-health” gap. It may be the case that users in disadvantaged groups are using Hello Heart to supplement less rich healthcare benefits, like high-deductible health plans, which often pay nothing until the member pays thousands of dollars out of pocket. Because people in high-ADI groups suffer more frequently from cardiovascular-related conditions, it may also be the case that Hello Heart users in these groups rely on Hello Heart to better manage and improve their heart health.

Sex and Physical Activity: Female users outpace men in January

Our final chart looks at the most common New Year’s resolution—”work out more and be more physically active”—comparing female and male Hello Heart users. This chart shows the average number of daily activities tracked via Hello Heart’s integration with Google Fit and Apple Health. Activities can include walks, runs, and more.

Avg. # of daily activities - Male vs. Female

Both male and female users trend in the same direction each month, with a statistically significant (p<0.01) increase in activity in January, followed by a gradual decline in February, and then a much steeper decline in March. (Notably, users still exercised more in March than they did in November or December.) This chart seems to be a strong indicator that users are making resolutions to increase their physical activity, but unlike our measurements of blood pressure readings and app sessions, they are having a more difficult time sticking with it after a month or two. Also worth noting is that female users increased their physical activity by 14% more than their male counterparts between December and January.


While we know that around half of the individuals who make a New Year’s resolution fail to continue that resolution beyond January, Hello Heart’s data shows encouraging signs that our digital heart health program helps users build and maintain healthy habits even if they aren’t always sticking to their lofty New Year’s goals. This is particularly true for blood pressure readings and number of app sessions. The Hello Heart app uses a unique blend of digital coaching, AI, and behavioral science to empower users—in a fun and easy way—to reduce their blood pressure, take control of their heart health, and catch serious heart issues before they occur.

About Hello Heart

Hello Heart is a clinically-based digital therapeutics program that helps people understand, track, and improve their heart health and heart-related chronic conditions, including hypertension and diabetes. Hello Heart’s AI-powered smartphone app and connected bluetooth blood pressure monitor make it fun and easy for users to build healthy habits and improve their overall health. And it works. A recently published 3-year UCSF study of 28,189 Hello Heart users with elevated blood pressure or hypertension showed that Hello Heart caught 11,637 potential hypertensive crises in time. For users with a baseline blood pressure above 140/90, the study also found that 84% sustained a reduction in blood pressure for the duration of the study, and the average reduction in systolic blood pressure for this group was 21mmHg over three years.
