Para dokter dan para netter
Yth.
Salam kenal dan salam kasih
selalu,
Saya punya putri berumur
4 bulan, dan karena beberapa alasan, saya berencana
untuk tinggal di rumah orangtua
dimana rumah tersebut dilalui kabel listrik
tegangan tinggi (500KV ?)
di sekitar daerah cawang-kali malang, yang
sekarang dapat terlihat
dari tiang listriknya yang dipasangi lampu
berkelap-kelip oleh PLN.
Nah, pertanyaan saya adalah
apa efek positif / negatif bila saya dan
keluarga pindah ke rumah
tersebut ?
Saya sangat berharap akan
informasi dari rekan-rekan sekalian.
Terima kasih.

Sudah lama ada persangkaan
(effek negatif) bahwa kabel listrik
tegangan tinggi bisa meyebabkan
leukemia (kanker darah) dari anak2 (childhood
leukemia) yang tinggal didekat
kabel listrik itu. Tetapi sampai sekarang
belum terbukti dan juga
belum bisa disangkal tentang "resiko bisa terjadinya
dari leukemia dari anak2
kerena pengaruh dari kabel listrik tegangan
tinggi". Effek positivenya
tidak ada.
Menurut pendapat saya,
kalau ada kemungkinan lain, janganlah pindah
kerumah itu.

OBJECTIVES:
This article uses meta-analysis methodology to examine the
statistical
consistency and importance of random variation among results of
epidemiologic
studies of residential magnetic field exposure and childhood
leukemia.
METHODS: A variety of meta-analytic statistical methods were
applied
to all available studies combined and on sub-groups of studies
chosen
by exposure characteristics. Sample sizes and fail-safe n's were
calculated
to determine the robustness of results and the potential role of
publication
bias. RESULTS: Most studies show elevated but not statistically
significant
odds ratios. Results for exposures assessed by wire codes,
distance,
and/or historically reconstructed fields are relatively
consistent,
homogeneous, and positive, while those for direct magnetic field
measurements
are consistent, homogeneous, and marginally protective. Several
unpublished
studies, or a single unpublished study with several hundred
subjects,
would be needed to nullify the observed data. CONCLUSIONS: The
observed
results identify a consistent risk that cannot be explained by
random
variation. The data supporting magnetic fields as the principal risk
factor
are suggestive but inconsistent. Additional studies using innovative
designs
that focus on highly exposed children offer the most hope of
untangling
this issue.
