Background
Childhood obesity has become a major public health concern in China

Overweight and obesity prevalence in older children
› For 7-15 year olds the national
obesity prevalence:
from less than 0.5% in 1985 to
around 13% in 2005 in boys
living in urban settings

Reported associated factors in China
- Low exclusive breastfeeding and ‘any’ breastfeeding, 15.8% and 49.2%
at 6 months, respectively
- Started complementary food too early (before 4 months) or too late
- Imbalanced complementary feeding, higher carbohydrate-based
- Poor infant feeding knowledge and practices
- Others
• Delivery by C-section
• High birth weight of the newborns
• Higher BMI parents, particularly mother's pre-pregnancy BMI

SMS or web-based interventions have proven to be effective in
(mhealth, ehealth):
› Behaviour change
- smoke cessation
- dietary behaviour change
- physical activity and weight management
› Patient management
› patients’ blood pressure and diabetes management
- Adhesion to anti-viral therapy
› Disease surveillance

The project
› Aim: to evaluate the feasibility and effectiveness of SMS in
support of breastfeeding and infant feeding in urban China

Community health centre (CHC) 社区卫生服务中心:
- A pregnant woman is required to register and receives the ‘Pregnant
Women Healthcare Card’ around 12 weeks gestation at the CHC
This is the best time to reach nearly 100% of the pregnant women.
- After giving birth, the new mother is referred back to the CHC in her
household registration area to be followed up by the CHC in the first 6
weeks.
- CHC is also responsible for child growth and development check ups
from 0-6 years: 4 scheduled health checks in the first year (around 2, 4,
6 and 9 months), twice yearly from 1-3 years, and yearly thereafter.

Short message service (SMS):
- The advantages of using SMS to support interventions for
new mothers:
- avoidance of travel to health facilities and waiting time
- flexible program delivery
- messages can be delivered quickly and simultaneously to
a large group of mothers
- communication can be interactive between health
providers and mothers with tailored response
- relatively low cost
13
The Intervention
› We developed a community-based health promotion
program to support new mothers to breastfeed their
babies and to adopt healthy infant feeding practices using
SMS.
› The study was carried out in four Community Health
Centers (CHCs). Two CHCs were assigned to the
intervention group and two other CHCs were assigned as
the control group.
› Communications technologies such as SMS
have enabled us to deliver the innovative
public health program.
15
The pilot study and findings
The participants:
› Total 657 pregnant women recruited
› Mean age 28 years, (range 20-42)
› Education levels: 83% college or above
› Professions: 48% professionals or management jobs
› Intended time to return to work after giving birth: 73% by 6 months

4. Feasibility and acceptability
›Delivering health promotion intervention by SMS appears not only
feasible but is well accepted by new mothers with a high retention
rate of 89% at 12 months
5. Median duration of exclusive breastfeeding
›Compared with the control group, the intervention group had a
significantly longer median duration of EBF at 6 months (11.41
weeks, 95% confidence interval [CI] 10.25 - 12.57 vs 8.87 weeks, 95%
CI 7.84 - 9.89; P<0.001)

Conclusion
• There is a gap in pregnant women and new mothers’ awareness of the
Who breastfeeding guidelines and knowledge on breastfeeding (Jiang et al,
Breastfeeding Medicine, 2012)
• The current health care can not meet the need (Yang et al, Chinese Maternal
and Child healthcare 2011)
• 95 % pregnant mothers in this study use mobile phone, 86% willing to
receive health promotion SMS (Yang et al, Chinese Maternal and Child
healthcare 2011)
• Delivering health promotion intervention by SMS appears not only feasible
but is well accepted by new mothers (Jiang et al, Lancet, 2013)
• SMS health promotion intervention improves median exclusive
breastfeeding duration and rate at 6 months and reduce early introduction
of solid foods (Jiang et al, Lancet, 2013)
