In the last 150 years - yes, not much.
In the last 150 years, there has been such a trend as acceleration (from the Latin "acceleration"). This term denotes the accelerated development of subsequent generations in comparison with previous ones. Not only growth and body weight increase, but also maturation itself occurs earlier: milk teeth change to permanent ones earlier, puberty occurs earlier.
The reason for this is still unclear, but given that the trend has been observed since the industrial revolution, the main suspects are clear. It is most likely to blame for the improvement in living conditions, nutrition and medical care.
