Yes. Statural growth acceleration has been reported to occur in the age range 6.5–8.5 years for some individuals (termed the mid-growth

spurt) . Reports on the magnitude of change in statural growth velocity

vary in characterization from “less deceleration” to mild acceleration, and of considerably lower magnitude, compared to pubertal growth acceleration . Mid-growth spurts in facial growth velocity havealso been shown in some individuals.

Yes, other growth accelerations occur before puberty. Notable periods include:

• Infancy: Rapid growth in the first year.
• Early Childhood: Steady growth until about age 4-5.
• Mid-Childhood: A slight growth spurt around ages 6-8.

Adolescent growth spurt is the fast and intense increase in the rate of growth in height and weight that occurs during the adolescent stage of the human life cycle. This growth practically occurs in all of the long bones and most other skeletal elements. No other primate species, including the chimpanzee, is known to have such a global post-pubertal increase in skeletal growth velocity.The pubertal growth spurt begins on average at 9-10.0 years for girls and 11-12.0 for boys, however there is considerable variation between individuals and populations. The peak growth rate as well as the duration of this spurt is greater for boys than for girls, and this accounts for the average difference of 11-13 cm in height between adult males and females. Up to 10% of clinically normally girls, usually those who sexually mature at a late age, experience a reduced or absent growth spurt.Individual adolescents vary in the timing of pubertal onset, its duration or “tempo,” and its termination. Little is known about the “offset” mechanisms of puberty. There are a number of variables that may influence directly or indirectly pubertal growth spurt including, gender, genetics, nutrition, endocrine regulation, physical activity and ethnicity . It is the interaction among several of these variables that may affect pubertal growth and maturation in complex ways. Children with short stature, who enter puberty at normal time, comprise a large portion of the typical pediatric endocrinologist's practice. Possible strategies for increasing adult height include growth hormone treatment alone or together with GnRH analog or with AIs therapy to suppress pubertal development. These approaches are expensive and invasive (requiring repeated injections), and GnRH analog and AIs therapy may result in potentially adverse effects in children whose puberty is occurring at a physiologically normal time. Additional controlled studies for their efficacy and safety are required before this therapy can be routinely recommended to augment adult height.
