Post-traumatic stress disorder (PTSD) increases the risk of cardiovascular disease and type 2 diabetes. PTSD has been found to associate with reduced cardiac contractility, cardiac ischemia, inflammation, and insulin resistance. Some lifestyle factors, including smoking, alcohol consumption, poor diet, and lack of physical activity, are believed to increase cardiometabolic disease risk in individuals with PTSD.

Dog ownership is known to improve cardiac health in the general population. Evidence suggests that dog ownership might be considered as an alternative intervention for improving PTSD condition. A large-scale study on the Swedish population found an association between dog ownership and reduced cardiovascular mortality risk over a follow-up period of 12 years.

In the current study, scientists have explored the effect of dog or cat ownership on the risk of cardiometabolic disease among US military veterans. Study design

The National Health and Resilience in Veterans Study (NHRVS), which includes multiple online surveys, was initiated in 2011 to evaluate the association between psychological health and successful aging among US military veterans. Data from the most recent cohort (2019 – 2020) of the NHRVS was used in the current study.

A total of 4,069 veterans participated in the first survey in November 2019. The second survey, which included questions about dog and cat ownership, was conducted on 3,078 veterans in November 2020. 

The presence of certain cardiometabolic diseases, including heart disease, heart attack, high cholesterol, hypertension, stroke, and diabetes, was assessed in the surveys. The presence of lifetime PTSD, major depressive disorder, alcohol use disorder, nicotine use disorder, and substance use disorder were also assessed. Regarding lifestyle factors, the weekly frequency of physical exercise was assessed.     Important observations

About 99% of survey participants responded about dog or cat ownership. Specifically, about 39% and 24% of participants responded affirmatively about dog and cat ownership, respectively.

The analysis of non-adjusted self-reported data revealed significantly lower prevalence of heart disease, high blood pressure, diabetes, and high cholesterol among dog owners compared to that among non-dog owners. However, no significant effect of cat ownership was observed on the prevalence of any cardiometabolic conditions.

Dog owners were found to be younger than non-dog owners and were more likely to be female. A higher prevalence of tested psychological disorders and addictive behaviors was observed among dog owners compared to that among non-dog owners. In addition, dog owners were found to be more physically active than non-dog owners.

The analysis of self-reported data after adjustment for age, sex, trauma load, psychological disorders, addictive behaviors, and exercise revealed that dog ownership is significantly associated with a lower risk of high blood pressure and high cholesterol.    

Considering participants’ physical exercise levels, the analysis revealed a reduction in heart disease risk with the induction of habitual exercise among dog owners. Moreover, dog owners showed a significantly lower risk of high blood pressure than non-dog owners, even with more lifetime traumatic events.

Considering the age of participants, the analysis revealed a higher risk of diabetes among dog owners over 80 years compared to age-matched non-dog owners. Similarly, a comparative higher risk of stroke was observed among dog owners aged over 70 years.

Among participants without nicotine use disorder, having a dog was found to reduce the risk of stroke. In contrast, an increased risk of stroke was observed among dog owners who had nicotine use disorder. Study significance

The study reveals that having a dog may reduce the risk of high blood pressure and high cholesterol among US military veterans. However, a negative impact of dog ownership on the risk of diabetes and stroke has been observed among older veterans and those with nicotine use disorder. Future studies are needed to establish these correlations more firmly.

Overall, the study highlights the benefits of having a dog in terms of reducing the risk of PTSD-related cardiometabolic disease. Journal reference: Woodward, S., Baldassarri, S. and Pietrzak, R.

Honda, Hyundai, Ford, Subaru, and Kia EV sales climb in January

Several automakers, including Honda, Hyundai, Ford, and Kia, reported higher EV sales in the US in January. Here’s a look at some of the top-selling EV models (outside of Tesla) last month.

EV sales in the US by model in January 2025

With nearly 133,000 electric vehicles sold in December, EVs accounted for 8.8% of new car sales in the US, a new record.

According to Cox Automotive’s Kelley Blue Book, the strong end-of-year sales helped push total EV sales to 1.3 million in 2024, up 7.3% from 2024.

With Trump reportedly planning to end electric vehicle incentives, like the $7,500 federal tax credit, demand is expected to pick up as buyers look to lock in the savings before they disappear.

Several automakers reported US sales numbers for January, giving us a better idea of how the EV market is playing out.

Ford sold 5,666 EVs last month, up 21% and a new January record. The Mustang Mach-E had its best January with 3,529 models sold, up 173% from January 2024. Last year, the Mach-E was the second best-selling electric SUV behind Tesla’s Model Y. This year, it’s already losing ground.

Despite higher demand for the Mach-E, Ford F-150 Lightning sales slipped 15% to 1,907 units. Ford’s E-Transit electric van sales also fell 80%, with only 230 models sold last month.

Kia sold 1,542 EV6 models sold last month. However, sales of its three-row EV9 were down slightly (1,232 vs 1,408 in January 2023).

Sister company Hyundai notched double-digit sales growth with its popular EV models. As the upgraded 2025 model (with more range and an NACS port for charging at Tesla Superchargers) rolled out, Hyundai IONIQ 5 sales climbed 54%, with 2,250 units sold in January. Although IONIQ 6 sales were up 15% year over year (YOY), only 871 models were sold.

The biggest surprise, again, was Honda. Honda’s electric Prologue continued to take the US by storm with another 3,744 models sold last month.

After delivering the first models last March, the Prologue was the seventh best-selling EV in the US in 2024. Honda sold over 33,000 Prologue’s in the US in 2024, beating out the Chevy Equinox EV (28,874) and Rivian R1S (26,934).

GM doesn’t report monthly US sales numbers, so we’ll have to wait until April for quarterly sales to compare. Several others have yet to report January US sales. Check back for the latest numbers.

Tesla doesn’t report monthly US sales numbers, but earlier today, Electrek reported that the EV maker saw its first annual drop in sales in California last year.

Match appoints Zillow co-founder Spencer Rascoff as CEO

Match Group announced on Tuesday that Zillow co-founder Spencer Rascoff will serve as its new CEO.

Rascoff, who has served as a member of the online dating company’s board since March 2024, will replace Bernard Kim in the role, Match said.

“During his time on the Board, Spencer has demonstrated a strong strategic perspective and deep understanding of Match Group’s brands and opportunities,” said Match Group Chairman Tom McInerney, in a statement. “We are confident in his ability to drive the company’s next phase of innovation and growth.”

Along with the leadership change, Match announced better-than-expected fourth-quarter results but lackluster guidance. Match posted earnings per share of 59 cents on $860 million in revenue. That topped the 54 cents per share in earnings and $859 million in revenue expected by analysts polled by LSEG.

However, the parent of Tinder and Hinge issued disappointing revenue guidance for the first quarter. The company forecast sales of $820 million to $830 million for the quarter, falling short of the $853 million estimate from LSEG.

The shares sank 7% in extended trading after the report.

Rascoff, 49, is best known for his role at Zillow. He co-founded the real estate technology company nearly two decades ago and served in various roles, including CEO, before departing in 2019. The Harvard University graduate also founded online travel website Hotwire, which Expedia bought for nearly $700 million in 2003.

Match was fully spun out of Barry Diller’s IAC Group in 2020, but has had a tough run as an independent public company. Its market cap was about $30 billion at the time of the transaction and has since shrunk below $10 billion, reflecting a dramatic slowdown in revenue growth.

Last month, IAC said its board approved the spinoff of Angi, the home improvement market place the company acquired in 2017.
