Men Have Grown Twice As Much As Women Over Past Century, Study Shows 103
According to a new study published in the journal Biology Letters, men around the world have gained height and weight twice as fast as women over the past century. The Guardian reports: "We're seeing insights into how sexual selection has shaped the male and female body and how improved environments, in terms of food and a lower burden of disease, have freed us from our shackles," said Prof Lewis Halsey at the University of Roehampton. Halsey and his colleagues used data from the World Health Organization, overseas authorities and UK records to see how height and weight have changed with living conditions. The latter was measured by the human development index (HDI), a score based on life expectancy, time in education and per capita income, which ranges from zero to one.
Analysis of records from dozens of countries found that for every 0.2 point increase in HDI, women were on average 1.7cm taller and 2.7kg heavier, while men were 4cm taller and 6.5kg heavier. This suggests that as living conditions improve, both height and weight increase, but more than twice as fast in men than women. To see whether similar trends played out within countries, the researchers delved into historical height records in the UK where HDI rose from 0.8 in 1900 to 0.94 in 2022. During the first half of the century, average female height increased 1.9% from 159cm to 162cm, while average male height rose 4% from 170cm to 177cm. "To put this in perspective, about one in four women born in 1905 was taller than the average man born in 1905, but this dropped to about one in eight women for those born in 1958," Halsey said.
Writing in Biology Letters in a study titled "The sexy and formidable male body: men's height and weight are condition-dependent, sexually selected traits," the scientists speculate that women's sexual preferences may have fueled a trend for taller, more muscular men -- although in an age of obesity, heavy does not necessarily mean muscular. Stature and physique are prime indicators of health and vitality, Halsey said, while sexual selection also favors men who are better able to protect and defend their partners and offspring against others. "Women can find men's height attractive because, potentially, it makes them more formidable, but also because being taller suggests they are well-made," said Halsey. "As they've grown up, they haven't been affected by the slings and arrows of a bad environment, so they've reached more of their height potential. It's an indicator that they're well-made."

At first glance there seem to be (at least) two drivers for this IMHO:
Less men die so women have a larger pool of men to select from. Since evolution has them tend towards bigger stronger men, they get the boost.
Likewise women die less too, enlargening the pool of women to select from. Since men tend to choose women smaller / more petite than themselves, this is another evolutionary driver that solidifies the height gap.
A third point would be nutrition. Early plentiful nutrition is proven to enhance body mass and height. Nutrition has improved over most of the last century also causing this.

Also, IMHO, most straight men really overestimate how much of attraction is appearance-focused, and if they have trouble getting a date, obsess over things like working out rather than becoming a more appealing human being. I know straight men tend to be heavily appearance focused when it comes to women, but things like confidence are hugely important factors in how attractive men come across. It's a mix of factors. Also, whether the guy has enough of a brain to not do things that are a total turnoff. Like, if she doesn't smoke, and you do, maybe try not to smell like an ashtray? If she doesn't drink and you do, maybe don't insist on meeting in a bar?

The CDC publishes survey data for the size of Americans. I was looking through the data a few days back purely out of idle curiosity.
From CDC 1960-1962 [cdc.gov], for ages 18-64 the 50-th percentile man was 68.6 inches (174 cm) and 157 pounds (71 kg). While the 50-th percentile woman was 63.9 inches (162 cm) and 126 pounds (57 kg).
From CDC 2015-2018 [cdc.gov], for ages 20+ the 50-th percentile man was 69.1 inches (175 cm) and 193 pounds (87.4 kg). While the 50-th percentile woman was 63.5 inches (161 cm) and 161 pounds (73.1 kg).
So, over that time median American men grew half an inch and 36 pounds and American women shrank by a bit under half an inch and gained 35 pounds. Clearly something is going on. I haven't seen more recent data than 2018, but I expect the trend to continue.
Dammit! I read from the wrong column for 1960-1962 data. The correct values are:
For 1960-1962 ages 18-79 (tables 1 and 2): 50th percentile male height is 68.3 inches (173.5 cm) and 166 pounds (75.5 kg). The 50th percentile female height is 62.9 inches (160cm) and 137 pounds (62.3 kg)
So the change in 50th percentile from 1960-1962 to 2015-2018 is +0.8 inches and +27 pounds for men and +0.6 inches and +24 pounds for women.

So I'll ask the obvious question:
Have the gains in height and weight been offset anywhere?
For example in intelligence and related voting behaviors? Where oh where could I find an interesting example?

This trend is purely the result of infanticide of babies who are unlikely to become NBA stars.
