Which is the 4th leading risk factor for mortality worldwide, accounting for 6-9% of deaths?

• A. Physical inactivity
• B. Obesity
• C. Tobacco use
• D. High blood pressure

Answer: (A)

Physical inactivity is a major, preventable factor that raises the risk of death from several noncommunicable diseases, including heart disease, stroke, type 2 diabetes, and some cancers. Large global analyses have identified it as the fourth leading risk factor for mortality worldwide, accounting for roughly 6% to 9% of deaths. This spot reflects its wide reach and the fact that many people do not get enough daily movement, even though increasing activity can substantially lower risk. Policies and environments that promote everyday movement—like walking or cycling for transport, stairs over elevators, and active breaks at work—can meaningfully reduce this burden.
